What Is an IFMGA Guide? Training, Standards and What Climbers Should Know

An IFMGA guide is a mountain guide who has passed a training and assessment programme that meets the standards of the International Federation of Mountain Guides Associations (IFMGA). The certificate covers four areas of mountain work: rock climbing, ice climbing, mountaineering and ski mountaineering. It shows that a guide has been trained and tested for the job. It does not promise a safe trip or a summit, because mountains always carry some risk. This guide explains what IFMGA is, how a guide qualifies, what the training covers, and how that training helps with weather, difficult ground, altitude and emergencies in the Himalaya. It also lists a few questions to ask when you choose a guide, and it ends with a short note on Nepal's own association, NNMGA. IFMGA at a glance Topic Key fact Full name International Federation of Mountain Guides Associations. The French name is UIAGM and the German name is IVBV, so you may see all three on one badge. Started 1965, by mountain guide associations from Austria, France, Italy and Switzerland What it is An umbrella federation of national mountain guide associations. Its training page refers to 28 member associations. Areas covered Rock climbing, ice climbing, mountaineering and ski mountaineering Minimum training At least 94 training days, with at least 84 of them practical work in the mountains Ongoing learning At least one day of continuing professional development every year Proof of status The IFMGA badge and an official IFMGA membership card What does IFMGA mean, and what does the organisation do? IFMGA stands for International Federation of Mountain Guides Associations. It is an internationally recognised organisation that represents professional mountain guiding associations worldwide. The IFMGA promotes high standards of professionalism, technical skills, safety, and ethical practices in mountain guiding. Its recognition is widely respected in the international mountaineering community and reflects a guide's professional qualifications and commitment to safe mountain travel. In simple terms, the federation does these jobs: Sets the minimum training standards that member associations must follow. Sets standards for how guides work and behave. Speaks for the guiding profession to authorities and the public. Protects the IFMGA badge, which only approved guides may use. How does someone become an IFMGA-certified mountain guide? There is no shortcut. IFMGA describes a fixed order of steps, and each country's association runs them: Meet the entry requirements. An applicant must be an adult, which is normally 18. IFMGA also expects wide mountain experience, and its training page mentions a documented record of 55 varied routes. Exact rules can differ by country. Pass an entry exam. Complete the aspirant guide course. This is the basic training, and it includes theory. An aspirant is a trainee guide. Learn in practice under a supervisor. Gain work experience. IFMGA asks for at least 14 days of practical learning under experienced guides. Take the mountain guide course, which includes a theory exam. Pass the final assessment. The minimum training time is split across several areas: Training area Minimum days What it covers Mixed terrain 32 Snow, ice and rock Ski and winter training 32 Ski mountaineering and avalanche safety Rock climbing 20 Technical climbing and rescue Theory 7 Weather, first aid, caring for the environment Country-specific training 3 Local conditions Total 94 At least 84 days are practical These are minimums. Candidates also need experience between courses, so the full path usually takes years. News reports about Nepal describe around five years of training in Nepal and abroad. The real time depends on the country and on the person. What do IFMGA guides learn? Technical skills IFMGA lists avalanche evaluation, navigation, rescue techniques and route planning among the technical skills. Theory lessons cover weather, first aid and caring for the environment. The training scope includes rock and ice climbing, ski mountaineering, trekking and high-altitude expeditions. People skills IFMGA gives equal weight to what it calls soft skills: leadership, communication, coaching and risk management. A guide who climbs well but cannot explain a plan, or cannot lead a nervous client, is only half prepared. Professional standards Every IFMGA guide is expected to follow the Code of Professional Conduct. Guides must also attend at least one day of continuing professional development each year. The badge and membership card are how you can recognise a guide who has completed the full training. A training base, not a finish line Training builds a base. One IFMGA member, the New Zealand Mountain Guides Association, says its courses do not cover every area in depth and names high altitude as one example. For work on big mountains, guides build on the base with extra courses and years of experience. Why mountain judgment matters IFMGA says clearly that the risks of mountaineering cannot be removed. Its guides are trained to reduce and manage risk, and to make decisions in conditions that keep changing. Training and years of experience are meant to work together here. Judgment is not one big decision. It is many small ones through the day. Is the snow stable on this slope? Is the weather changing faster than the forecast said? Is someone in the team slowing down? Is there a safer line? Is it time to turn around? A good guide evaluates all of these and changes the plan when required for the safety of the team and success of the expedition. How guides handle weather, terrain, altitude and emergencies Changing weather Mountain weather can change rapidly, making careful planning essential for the safety of climbers. Guides assess weather forecasts alongside local conditions, including changes in the sky, wind, snow, and temperature, to make informed decisions throughout the expedition. Extra buffer days should always be included in the itinerary to allow flexibility when conditions are unfavourable. These days are especially important because they give the team time to wait for a safe weather window rather than feeling pressured to climb in unsuitable conditions. Difficult terrain On technical terrain, the guide assesses the route, selects the safest line of ascent, and manages ropes and anchors where necessary. In some expeditions, a rope-fixing team installs fixed ropes along sections of the route before climbers arrive. However, fixed ropes do not eliminate the need for technical climbing skills, as climbers must still understand the terrain, use their equipment correctly, and move safely. Ropes provide support but cannot replace climbing ability. In alpine-style ascents, fixed ropes are generally not used. Instead, the guide carefully studies the terrain, evaluates possible routes, and develops a clear mental picture of the line to follow, adapting the approach as conditions and obstacles change. Altitude Low oxygen levels are one of the biggest challenges when climbing Himalayan peaks. As altitude increases, the body needs time to adapt to the reduced oxygen availability, a process known as acclimatization. Climbers usually ascend gradually through a series of camps, spending time at higher elevations before returning to a lower camp to rest and recover. These rotations help the body adjust before moving to greater heights. The guide plans and monitors these rotations, observes each climber's condition, and adjusts the schedule when necessary. Climbers should also communicate any symptoms, such as headaches, nausea, dizziness, or poor sleep, as early as possible so the guide can respond appropriately. For further information, ACE's acclimatization guide summarises recommendations from the US Centers for Disease Control and Prevention (CDC) and the Wilderness Medical Society. This article is intended for general information and does not replace professional medical advice. Consult your doctor before undertaking a high-altitude expedition, particularly if you have any existing health concerns. Emergencies Mountain rescue procedures, emergency response, and first aid are important parts of IFMGA training. However, managing an emergency in the mountains depends on several factors, including the location, weather conditions, terrain, and availability of rescue support. In remote areas, evacuation can take considerable time and may be affected by difficult conditions. Before booking an expedition, make sure you understand the emergency evacuation procedures, insurance requirements, and who has the authority to make decisions about stopping the climb or descending for safety reasons. For expeditions operated by ACE, you can refer to our insurance policy page to understand the coverage and requirements before your trip. What a professional guide is responsible for IFMGA describes a guide's duty to clients as giving a high-quality experience while managing risk in technical terrain. In practice, that covers several things: Before the trip: helping you choose a suitable goal and prepare for it. On the mountain: leading, managing risk, and giving advice and coaching along the way. For the place: working in an environmentally responsible way and respecting the region's mountains and culture. For the team: on larger expeditions, a guide works with Sherpa climbers and other staff, so each person's role should be clear. The IFMGA Guidelines on Treks and Expeditions recognise different expedition styles, each with its own guiding arrangements and responsibilities. In some expeditions, the guide accompanies a small group throughout the climb, providing direct support on the mountain. In others, the guide may remain at Base Camp while experienced climbing Sherpas establish higher camps, fix ropes, and support climbers during their ascent. The guide's level of involvement and responsibilities above Base Camp can vary depending on the expedition structure. Before booking, ask how the expedition is organised, who will accompany you during the climb, and what responsibilities the guide and climbing Sherpas will have. Clients also have an important role in maintaining safety. Be honest about your previous climbing experience, physical fitness, and medical condition when discussing your trip with the guiding team. Follow the guide's instructions, communicate any concerns, and respect decisions made to protect the safety of everyone on the mountain. The role of IFMGA guides in Himalayan mountaineering IFMGA training includes high-altitude mountaineering within its scope. In the Himalaya, an IFMGA-certified guide may lead a small team on a peak, make critical decisions about route selection and turnaround times, and coordinate with Sherpa climbers and support staff. In Nepal, many mountain guides develop their skills and qualifications through the Nepal National Mountain Guide Association (NNMGA), which conducts parts of its training on the country's own mountains. Understanding these qualifications is an important first step when choosing a qualified mountain guide. The following section highlights what climbers should look for when choosing a qualified mountain guide for their expedition and gives a short note on NNMGA. What to know when choosing a qualified mountain guide A certificate is a good place to start, but it is not the whole decision. These questions can help: Who exactly will guide me? Ask for a name, not just a company. Which association certified the guide? For IFMGA guides, look for the IFMGA / UIAGM / IVBV badge and ask to see the official membership card. Is the guide listed? IFMGA's find a guide page explains how to look for one, and national associations often share lists of their members. Websites that use the badge should clearly show which people are IFMGA guides. What will the guide's role be on the mountain? Will the guide climb with you, or be based at base camp? How many climbers will each guide look after? What is the guide's experience on your peak or region? How is acclimatization planned? Look for rest days and spare days in the schedule. What is the plan for bad weather and for turning back? Ask who makes the call. What is the emergency plan? Ask about evacuation, communication and the insurance you must carry. What does the operator expect from you? Good operators ask about your experience and health before they accept you. A short note on NNMGA NNMGA is the Nepal National Mountain Guides Association. It is Nepal's member association in IFMGA, and it trains and certifies Nepali guides to IFMGA standards. According to the American Alpine Club, NNMGA was formed in 2004 and was fully accepted into IFMGA in 2012. The Himalayan Times reports that NNMGA launched its aspirant guide training in 2007 and that the first batch of international mountain guides graduated in 2009. The path in Nepal follows the IFMGA order. The Aspirant Guide Course has three components over about ten months, with 47 training days. The final stage is the mountain guide course. Recent reports describe it as a winter course of about two to three weeks. One report gave 15 training days, and another described a 19-day course in 2026 near Chulu East (6,584 m) for eight aspirant guides. Because course details change from year to year, check NNMGA's current information if you need exact figures. Where to go from here IFMGA certification shows that a guide has completed a long, structured training and works to a shared code. It sits beside other things worth checking: the guide's experience on your mountain, the team plan, the acclimatization schedule and the emergency plan. If you are thinking about a climb in Nepal and want to talk about routes, dates or who would guide you, you can look at ACE's expeditions or write through the contact page. Frequently asked questions What does IFMGA stand for? IFMGA stands for International Federation of Mountain Guides Associations. UIAGM is the French version of the name and IVBV is the German version. How long does it take to become an IFMGA guide? IFMGA sets a minimum of 94 training days, with at least 84 of them practical. Candidates also need experience between courses, so the full path takes years. News reports on Nepal describe around five years. The time varies by country and by person. Does an IFMGA guide guarantee safety or a summit? No. IFMGA itself says the risks of mountaineering cannot be removed. The certificate shows that a guide has been trained and assessed to an international standard. Weather, snow conditions, health and the team's decisions still shape every climb. How can I check if a guide is IFMGA certified? Ask for the guide's name. Look for the IFMGA / UIAGM / IVBV badge and ask to see the official IFMGA membership card. You can also use IFMGA's guide search or the member list of the guide's national association. What does an IFMGA guide do when the weather turns bad? Weather is part of the training. A guide watches forecasts and conditions, and may wait, change the route or turn the team around. ACE's Manaslu 2026 account is one example of a team turning back at due to extreme weather. Are all members of an expedition team IFMGA guides? No. Teams often include IFMGA guides together with Sherpa climbing staff and other support staff, and each role is different. Ask the operator who will be on your trip and what each person does. What is NNMGA? NNMGA is the Nepal National Mountain Guides Association, Nepal's member association in IFMGA. It runs the aspirant guide and mountain guide courses that lead to IFMGA certification in Nepal.

Mountaineering Royalty in Nepal: Fees, Liaison Officers, Garbage Deposit and Insurance

Mountaineering royalty is the fee you pay the Government of Nepal for permission to climb a Nepali peak. The Department of Tourism collects it for each climber. The amount depends on the height of the mountain, the route and the season. Foreign climbers pay in US dollars. Nepali citizens pay a lower fee in Nepali rupees. For a foreign climber, the Department of Tourism table runs from US$175 for a peak of 6,500 metres or lower in autumn, up to US$15,000 for Everest by the normal route in spring. Royalty is only one part of the government cost. Most expeditions also pay a garbage management deposit, cover the cost of a government liaison officer, and buy insurance for the Nepali team and the climbers. This guide explains each of these in plain language. The rates below took effect on 1 September 2025. They are the rates shown on the Department of Tourism website on 1 November 2026. Rules in this area are changing, so please read the section "What may change next" before you plan a trip for 2027. Key facts at a glance Who sets the royalty The Government of Nepal. The Department of Tourism collects it for the peaks in its fee table. Who pays Each climber, per person. Currency US dollars for foreign climbers. Nepali rupees for Nepali citizens. Current rates took effect 1 September 2025 (16 Bhadra 2082 B.S.) What decides the amount The height of the mountain, the route, and the season of the climb. Garbage deposit Paid by the expedition team. The amount depends on the height of the mountain and the mountain range. Liaison officer A government officer who goes with expeditions on the peaks in the Department of Tourism fee table. Insurance The team must insure its Nepali staff. Details of the climber’s own insurance are part of the permit application. How the royalty is worked out Three things decide the fee. • Height. Peaks are grouped by height: above 8,000 m, 7,501 to 8,000 m, 7,001 to 7,500 m, 6,501 to 7,000 m, and 6,500 m or lower. Higher peaks cost more. • Route. Everest is the only mountain with two route categories: the normal route and all other routes. • Season. Spring costs the most on almost every peak. Autumn costs less. Winter and summer share the lowest rate. The government groups the year like this: spring is March to May, summer is June to August, autumn is September to November, and winter is December to February. Two mountains have their own rows in the table. Manaslu is the one 8,000-metre peak where autumn costs more than spring, because autumn is its main climbing season. Ama Dablam has the same fee in spring and autumn. Royalty for foreign climbers All amounts are per person, in US dollars. These are the Department of Tourism rates in force from 1 September 2025. Mountain Spring Autumn Winter and summer Everest, normal route US$15,000 US$7,500 US$3,750 Everest, other routes US$10,000 US$5,000 US$2,500 Other peaks above 8,000 m (not Everest or Manaslu) US$3,000 US$1,500 US$750 Manaslu US$1,500 US$3,000 US$1,500 7,501 m to 7,999 m US$1,000 US$500 US$250 7,001 m to 7,500 m US$800 US$400 US$200 6,501 m to 6,999 m US$500 US$250 US$200 Ama Dablam (6,812 m) US$1,000 US$1,000 US$500 Below 6,500 m US$350 US$175 US$175 The Everest spring fee rose from US$11,000 to US$15,000 in this change. The old figure had stood since January 2015. Royalty for Nepali citizens Nepali citizens pay a separate fee in Nepali rupees (NPR), per person. The same rates took effect in September 2025. Mountain Spring Autumn Winter and summer Everest, normal route NPR 150,000 NPR 75,000 NPR 37,500 Everest, other routes NPR 100,000 NPR 50,000 NPR 25,000 Other peaks above 8,000 m (not Everest) NPR 50,000 NPR 25,000 NPR 12,500 7,501 m to 7,999 m NPR 40,000 NPR 20,000 NPR 10,000 7,001 m to 7,500 m NPR 30,000 NPR 15,000 NPR 7,500 6,501 m to 7,000 m NPR 25,000 NPR 12,500 NPR 6,250 Ama Dablam (6,812 m) NPR 40,000 NPR 20,000 NPR 10,000 Below 6,500 m NPR 20,000 NPR 10,000 NPR 5,000 The Nepali table has no separate Manaslu row. Manaslu falls under "other peaks above 8,000 m". Three quick examples • A foreign climber on a 7,200 m peak pays US$800 in spring or US$400 in autumn. • A foreign climber on Manaslu pays US$3,000 in autumn or US$1,500 in spring. • A Nepali climber on a peak of 6,500 m or lower pays NPR 20,000 in spring. What the royalty does and does not cover Royalty is the government’s permission to climb. It does not pay for the garbage deposit, the liaison officer, insurance, park entry, Nepali staff wages, flights, food or camps. Whether the royalty is already inside a package price depends on the operator, so check the quote. If the quote does not say, ask. Other permits and fees Royalty is the main climbing permit fee, but it is not the only one. Which ones apply depends on where you climb. Climbing permits are applied for through a registered Nepali agency. Climbers cannot apply on their own. Permit or fee Issued by Amount for foreign visitors Applies to NMA trekking peak permit Nepal Mountaineering Association Island Peak, Mera Peak and Lobuche East: US$350 in spring, US$175 in autumn, US$175 in winter and summer. Nepali climbers pay NPR 20,000, NPR 10,000 and NPR 5,000. Peaks managed by the NMA, instead of the royalty table above Restricted area permit Department of Immigration, through an agency Manaslu: US$100 for the first 7 days plus US$15 per extra day (September to November); US$75 plus US$10 per extra day (December to August). Upper Mustang and Upper Dolpo: US$500 for the first 10 days plus US$50 per extra day. Climbs and treks inside restricted areas National park or conservation area fee Park or conservation authority Sagarmatha National Park: NPR 3,000 plus 13% VAT. Manaslu and Annapurna conservation areas: about NPR 3,000 each. Entry to protected areas Local municipality fee Local government Khumbu Pasang Lhamu Rural Municipality: NPR 3,000 for most foreign visitors. Other municipalities set their own fees. Everest region and other local areas Park and local fees are small compared with royalty, and local governments can change them. Your operator should list the ones that apply to your route. Some lower and newly opened peaks carry no royalty at all. The government waived the fee on a number of them to encourage climbers to visit less-used areas. If you are choosing a lower peak, ask whether it has a fee. Garbage management deposit The garbage management deposit is a refundable payment that the expedition team makes to the government before the pre-expedition briefing. The idea is simple: the team gets the money back when it brings its waste down and hands it over as the rules require. The deposit is paid by the team, not by each person, and it can be paid in US dollars or the equivalent in Nepali rupees. The amount depends on the height of the mountain and on the mountain range. Schedule 9 of the mountaineering regulations sets two lists, shown below. Peaks in the Khumbu and Annapurna ranges Mountain Deposit per team Mount Everest US$4,000 Other peaks above 8,000 m US$3,000 7,001 m to 8,000 m, and Ama Dablam US$2,000 6,501 m to 7,000 m US$1,000 Below 6,500 m US$500 Peaks in all other Himalayan ranges Mountain Deposit per team Peaks above 8,000 m US$3,000 Peaks below 8,000 m US$500 Peaks managed by the Nepal Mountaineering Association have their own, smaller deposit, which is paid to the association. We confirm the current amount with you when you book. The Everest 8 kg rule Since 2014, every climber who goes above Everest Base Camp has had to bring back at least 8 kilograms of solid waste, or lose the US$4,000 deposit. Under rules introduced in 2025, Everest climbers must also bring human waste down to base camp and carry biodegradable bags for use higher on the mountain. The deposit is likely to change on Everest In December 2025 the tourism ministry approved a five-year clean-up plan for 2025 to 2029. Officials said the deposit scheme had not solved the waste problem. One reason is that many climbers collected rubbish from the lower camps, while the worst waste sits on the higher camps. The plan proposes to turn the Everest deposit into a non-refundable clean-up fee. Officials said it would most probably stay at US$4,000 per climber, and that the money would pay for mountain rangers and a checkpoint at Camp 2. A change like this needs a new law. The Integrated Tourism Bill includes it. The bill passed the National Assembly in February 2026. In July 2026 it was still under review in a committee of the House of Representatives, where lawmakers had proposed 263 amendments. We have not found confirmation that it has become law, and the Department of Tourism fee page still lists the refundable deposit schedule above. If you plan to climb Everest in 2027, ask your operator whether the amount will be refundable. Liaison officer What a liaison officer is A liaison officer is a Nepali government officer who joins an expedition to represent the government. The Tourism Act of 1978 (2035 B.S.) says that a team with a mountaineering permit must take the liaison officers the government assigns. The same law lets the government name peaks where a liaison officer is not needed. When a liaison officer is needed In practice, a liaison officer is required on the expedition peaks in the Department of Tourism fee table. These are generally the peaks above 6,500 m, such as Everest, Manaslu, Ama Dablam and the 7,000 m and 8,000 m peaks. Trekking peaks managed by the Nepal Mountaineering Association, such as Island Peak and Mera Peak, do not need one. If you are unsure about a particular peak, especially a newly opened one, ask your operator before you plan your budget. What a liaison officer does The regulations give the liaison officer these main jobs: • stay at base camp while the expedition is on the mountain • receive daily updates from the team on its condition and plans • help solve problems the team meets, and help arrange rescue if a team member or staff member is in trouble • pass news and reports from the team to the government • approve any urgent change of route A liaison officer is a government representative. He or she is not a guide and does not replace your climbing guides or Sherpa team. Who pays for the liaison officer The expedition team pays. Since the 2025 amendment, the daily allowance is NPR 1,600 per day, up from NPR 500. The team also provides the officer’s travel, food, lodging and equipment, and insures the officer. The total depends on how long the expedition lasts. One 2026 cost guide for Everest puts it at about US$5,000 per team, and says operators usually include it in their price. Ask your operator whether your quote includes it. Insurance provisions Insurance the team must buy for Nepali staff The regulations require the expedition team to insure its Nepali staff with an insurer the government recognises. The cover must run from the day the team leaves for the expedition until the day it returns. It has two parts. 1. Personal accident insurance. The team must cover the liaison officer, the sirdar (the head Sherpa), mountain guides, high-altitude workers and base camp workers. The minimum amounts are: Role Minimum personal accident cover Liaison officer NPR 1,500,000 Mountain guide and high-altitude worker NPR 2,000,000 Base camp worker NPR 1,500,000 Local worker NPR 500,000 2. Medical insurance for minor injuries. The team must also insure the liaison officer, sirdar, mountain guides, high-altitude workers, base camp workers and local workers for minor injuries in an accident. The sixth amendment to the regulations, published in the Nepal Gazette in February 2025, raised the minimum cover for guides and high-altitude workers. The earlier minimum was far lower. Your own insurance as a climber A copy of the climber’s insurance, together with a map of the expedition area, is now part of the permit application. Before you buy a policy, check these points: • It covers mountaineering, up to the highest altitude of your peak. Many standard travel policies stop at a lower altitude. • It covers emergency evacuation, including by helicopter, and treatment in hospital. • It covers repatriation, and trip cancellation or interruption. The policy wording decides what is covered, so read it or ask the insurer. For how insurance works on our trips, see our Insurance Policy page. Other rules that affect the budget • Guides are required. On peaks above 8,000 m, there must be at least one mountain guide or high-altitude worker for every two climbers. On other peaks, a team must take at least one guide. Solo expeditions on 8,000 m peaks are no longer allowed. • Royalty is not refundable. Under our Terms and Conditions, climbing permit costs cannot be refunded once they are paid. What may change next The Integrated Tourism Bill would bring the mountaineering rules into a single law. As far as we can find, it is not in force. It was not in force for the spring 2026 season, and it was still in the House of Representatives in July 2026. Proposals in the bill include: • a non-refundable garbage fee, paid into a new Environment Protection and Mountaineers’ Welfare Fund • proof of a previous summit above 7,000 m in Nepal before an Everest permit is issued • a health certificate issued within the previous month for every team member • wider insurance, covering personal accident, medical treatment, search and rescue, and the handling of a climber who dies on the mountain • no royalty refund if an expedition is abandoned, except that royalty already paid may be applied to another permit within two years if war, disaster or an epidemic stops the climb Lawmakers have suggested many changes to the bill, so the final law may differ. We will update this page when the situation changes. Frequently asked questions What is mountaineering royalty in Nepal? It is the fee that a climber pays the Government of Nepal for a permit to climb a peak. The Department of Tourism collects it. The amount depends on the height of the mountain, the route and the season. How much is the Everest royalty for foreign climbers? On the normal route, it is US$15,000 in spring, US$7,500 in autumn and US$3,750 in winter and summer. On other routes it is US$10,000, US$5,000 and US$2,500. These rates took effect on 1 September 2025. How much do Nepali citizens pay? Nepali citizens pay in rupees. On the Everest normal route the fee is NPR 150,000 in spring, NPR 75,000 in autumn and NPR 37,500 in winter and summer. For a peak of 6,500 m or lower, it is NPR 20,000, NPR 10,000 and NPR 5,000. Is royalty charged per person or per team? Royalty is charged per person. The garbage management deposit is charged to the expedition team. When do I need a liaison officer? You need one on the expedition peaks in the Department of Tourism fee table, which are generally the peaks above 6,500 m. You do not need one on NMA trekking peaks such as Island Peak and Mera Peak. Who pays for the liaison officer? The expedition team pays for the officer’s daily allowance of NPR 1,600, plus travel, food, lodging, equipment and insurance. Check whether your operator’s quote includes it. Is the garbage deposit refundable? At present, yes. The deposit is returned when the team brings back its waste as the rules require. For Everest, the government plans to replace it with a non-refundable fee, but that change needs a new law, and we have not found confirmation that it has passed. What insurance does an expedition need? The team must insure its Nepali staff for personal accident and for minor medical injuries, for the whole expedition. The minimum personal accident cover is NPR 2,000,000 for guides and high-altitude workers, NPR 1,500,000 for the liaison officer and base camp workers, and NPR 500,000 for local workers. The climber’s own insurance details are part of the permit application, and the climber should have cover for mountaineering, emergency evacuation and repatriation. Can I get my royalty back if I cancel? Not with us. Under the Alpinist Climber Expeditions Terms and Conditions, climbing permit costs cannot be refunded once they are paid. Do Everest Base Camp trekkers pay royalty? No. Royalty is a fee for climbing. Trekkers pay park and local entry fees instead. How often do the rates change? Not often, but the changes can be large. The Everest spring fee stayed at US$11,000 from January 2015 until it rose to US$15,000 in September 2025. Always confirm the current rate before you book. How Alpinist Climber Expeditions handles permits and fees We apply for your climbing permit and the related permits on your behalf. Your quote lists which permits and fees are included and whether the royalty is part of the package price or charged separately. We confirm the exact fees for your mountain, route and season before you book. Our rates summary is on the Mountaineering Royalty page, and our Terms and Conditions explain what happens to permit costs if plans change. If you have a question about a fee or a rule, contact our team at info@alpinistclimberexpeditions.com or on WhatsApp at +977 9843314253. You can also look at our 6,000 m, 7,000 m and 8,000 m expeditions to see which fee category your peak falls under.

Alpinist and Alpinism: Alpine Style Climbing vs Mountaineering

An alpinist is a climber who practises alpinism. That means climbing mountains with a mix of rock, snow and ice skills, usually in a light, fast and self-reliant way. The word comes from the Alps, where this kind of climbing began. Alpine style is one way of doing it. In alpine style, a small team carries everything it needs and climbs from base to summit without fixed ropes, high-altitude porters or a chain of stocked camps. Expedition style is the opposite approach. The team builds camps up the mountain, moves supplies in stages and often fixes ropes on steep ground. On the highest peaks of the Himalayas, this is still the usual way to climb. This guide explains how the two styles differ, how climbers train for each one, and how to decide which suits you. It is written for climbers planning a trip to Nepal, whether it is your first Himalayan peak or your tenth. The short version • Alpinism: the craft of climbing mountains using rock, snow, ice and glacier skills. • Alpine style: a light, fast approach. A small team, everything carried by the climbers, and one continuous push from base to summit. • Expedition style: a slower, supported approach with a series of camps, supplies moved up in stages, and often fixed ropes. • Mountaineering: the wider term that includes both styles. • Main trade-off: alpine style is lighter and quicker but leaves less room to retreat or wait out bad weather. Expedition style gives more backup but takes more time and logistics. What is alpinism, and who is an alpinist? Alpinism began in the European Alps. Today it is practised in the Himalayas, Patagonia and many other remote ranges. An alpinist climbs routes that may combine rock, ice, snow and mixed ground, often over long days. How you climb a route matters as much as reaching the top. Alpinists also tend to choose routes that are well within their technical ability. This is not timidity. Long mountain routes add rockfall, avalanches, changing weather, altitude and tricky navigation, so a margin of skill is a safety tool. Are alpinism and mountaineering the same thing? People often use the two words as if they mean the same. They overlap, but they are not identical. Mountaineering is the broad word for climbing mountains. It covers a walk up a snow slope on a normal route as well as a hard technical ascent. Alpinism usually points to the technical end of that range, where a climber needs rock, ice and glacier skills together. Alpine climbing is generally treated as one type of mountaineering, not a separate activity. Climbers do not all draw the line in the same place, so it helps to look at what a trip actually involves. Rolwaling Multi Pitch Ice Climbing What is alpine style climbing? Alpine style is a light, fast way to climb in which a small team carries all its gear and climbs from base to summit without fixed ropes, high-altitude porters or stocked camps. Expedition style is the slower, supported alternative, with camps, fixed ropes and supplies moved up in stages. Both are forms of mountaineering. Alpine style describes how a climb is done. It does not describe how high or how hard the mountain is. Most definitions include these points: • A small team. • The climbers carry their own food, shelter and equipment. • No fixed ropes put in place for the climb. • No high-altitude porters or support climbers carrying loads up the mountain. • No stocked camps set up in advance on the mountain. • Usually no supplementary oxygen. • One continuous push from the base of the route to the summit and back. Support up to base camp is generally accepted. What matters is what happens on the mountain itself. Climbers still debate how strict the rules should be. Some add more conditions, such as no acclimatising on the route itself and no use of ropes or tracks left by other teams. Others treat alpine style as an ideal to aim for, not a checklist. For that reason, it is fair to ask any company that offers alpine style climbs exactly what they mean by the term. A short history Light, fast climbing started in the Alps, where small teams took on large rock and ice faces. In the Himalayas, many climbers believed the highest peaks could only be climbed by big expeditions. That view began to change in 1975, when Reinhold Messner and Peter Habeler made what is usually named as the first alpine style ascent of an 8,000 m peak: Gasherbrum I, in Pakistan. Lightweight attempts on big mountains had been made before then, but the 1975 climb is the one most often named as the turning point. Alpine style vs expedition-style mountaineering On the biggest Himalayan peaks, "mountaineering" usually means expedition style. So this is the comparison most climbers are really asking about. These are the main differences. Alpine style Expedition style Team Small team Often a larger team, with support staff Camps No stocked camps. The team carries its shelter and moves up together. A series of camps built up the mountain, with supplies moved in stages Fixed ropes Not used Often fixed on steep or exposed ground Porters and support above base camp None Often used, especially on the highest peaks Time on the mountain Shorter. One push once the team is ready. Longer. Big peaks can take weeks, sometimes months. Acclimatisation Done before the main climb, so the team arrives on the route acclimatised Built up gradually by moving between camps Supplementary oxygen Usually not used Sometimes used on the highest peaks Room to retreat Less. No camps or fixed ropes to fall back on. More. Camps and ropes give shelter and a way down. Footprint on the mountain Lighter Heavier, because of the logistics Where it fits best Technical peaks where speed and self-reliance matter The highest peaks, where size, altitude and weather call for more time and support Neither style is better in every case. They suit different mountains, different climbers and different goals. How alpinists train Both styles need a strong engine and good judgement at altitude. The training focus is different. Training for alpine style • Long-day endurance. Alpine days often last 12 to 18 hours, sometimes more. Training builds the ability to keep a steady pace for that long while eating and drinking well. • Strength endurance under load. Hill and stair work with a loaded pack, because on an alpine style climb you carry everything yourself. • Technical skill. Rock, ice and mixed climbing, building anchors, abseiling, rope work on glaciers, and crevasse rescue. These skills are not learned in a gym. They are learned on real terrain, ideally with a qualified instructor or guide. • Speed and efficiency. Moving together on the rope over easier ground, quick transitions, and well-organised gear. • Judgement. Reading weather and snow conditions, knowing your partners' strengths, and being willing to turn around. • Time at altitude. A study discussed by the UIAA Medical Commission linked four days spent above 3,000 m in the two months before a climb with better protection against acute mountain sickness. Training for expedition-style mountaineering • A fitness base for weeks, not days. Expedition climbs include repeated carries between camps and several hard days in a row. • Fixed-rope skills. Using ascenders, abseiling on fixed lines, and moving safely on ropes shared with other teams. • Camp skills in the cold. Managing food, hydration, sleep and warmth in tents at altitude over many days. • Patience and teamwork. The pace is slower, and the schedule depends on weather and acclimatisation. Humde Ice Climbing Training What both styles need Acclimatisation comes first in both. The UIAA Medical Commission notes that up to about 5,000 to 6,000 m, altitude illness mostly results from inadequate acclimatisation, and it treats a sensible, gradual ascent as the best prevention. This is general information, not medical advice. Please speak with a doctor who knows altitude medicine before a high-altitude trip. A fair test of readiness is to climb routes that come close to the demands of your goal, then judge honestly how you coped. A guide or coach who knows alpine climbing can help you make that assessment. How to choose between the two styles Alpine style may suit you if you: • already have solid rock, ice and glacier skills, • are comfortable making decisions with less backup, • prefer small teams and a light footprint on the mountain, • are aiming at a technical peak rather than an 8,000 m giant. Expedition style may suit you if you: • want a slower build-up to high altitude, with camps to retreat to, • are aiming at the highest peaks, where time and support matter more, • want more backup on the mountain while you build experience, • prefer a larger team and a steadier rhythm. Many climbers build up in steps: supported climbs first, then smaller alpine style goals as their skills and confidence grow. If you are not sure where you stand, tell us your experience and we will suggest a sensible next step. Risks to understand before you commit Alpine style has less margin for error. Without fixed ropes or stocked camps, a team that meets a storm or an injury cannot simply sit it out or descend a prepared line. In remote mountain ranges, rescue can take a long time, and sometimes self-rescue is the only practical option. Expedition style has its own risks, including long exposure to altitude and hazards such as avalanches and falling ice. No company can guarantee summit success, good weather or safety. What a good team can do is prepare carefully, match the objective to the climbers, and be ready to turn back. IFMGA Prakash Sherpa Climbng Mt. Malangphulang in Alpine Style Alpine style and mountaineering expeditions with Alpinist Climber Expeditions Alpinist Climber Expeditions (ACE) is a Nepal-based company that has run high-altitude expeditions in the Himalayas since 2021.

Frequently asked questions What is an alpinist? An alpinist is a climber who practises alpinism. That means climbing mountains with a mix of rock, snow, ice and glacier skills, often in a light and self-reliant style. The word comes from the Alps, where this type of climbing began. What is the difference between alpinism and mountaineering? Mountaineering is the wider term for climbing mountains, from simple snow walks to hard technical ascents. Alpinism usually refers to the technical end, where climbers need rock, ice and glacier skills together. Alpine climbing is generally seen as one type of mountaineering, though climbers do not all draw the line in the same place. What is alpine style climbing? Alpine style is a light, fast way of climbing. A small team carries all its food, shelter and gear and climbs from base to summit without fixed ropes, high-altitude porters or stocked camps. Support up to base camp is generally accepted. What is the difference between alpine style and expedition style? In expedition style, a larger team builds a series of camps, moves supplies up in stages and often fixes ropes. It takes longer but gives more backup. In alpine style, the team goes light and climbs in one push. It is quicker, but leaves less room to retreat or wait out bad weather. Is alpine style more dangerous than expedition style? The risks are different. Alpine style has less margin for error because there are no fixed ropes or stocked camps to fall back on. Expedition style means longer exposure to altitude and mountain hazards. The risk on any climb depends on the peak, the route, the conditions and the skill of the team. Can you climb 8,000 m peaks in alpine style? Yes, but it is rare and very demanding. The first alpine style ascent of an 8,000 m peak is usually dated to 1975, on Gasherbrum I. Expedition style is still the usual approach on the 8,000 m peaks. Can I climb alpine style with a guide? Yes. On a guided alpine style climb, a qualified guide leads and makes the safety decisions while the team climbs in the alpine style. Details differ between companies, so ask what support is used and where. ACE alpine style expeditions are led by IFMGA-certified guides and experienced climbing Sherpas. Do I need technical climbing experience for alpine style? In general, yes. Alpine style asks climbers to be comfortable on rock, ice and glaciers and to look after themselves with little backup. Requirements differ by peak. Send us your experience and we will tell you which of our expeditions fit. Does ACE offer alpine style expeditions in Nepal? Yes. ACE has offered dedicated alpine style expeditions since 2021. Our alpine style packages are Kyajo Ri, Cholatse and Malangphulang. You can see them on our alpine style expedition page.

Nepal Visa Requirements 2026: Fees, Forms and Who Can Get a Visa on Arrival

Visa rules can change. Please open the official links in this guide before you travel. Almost every visitor to Nepal needs a tourist visa. The main exception are citizens of India. Most travellers can get the visa when they arrive at Kathmandu airport or at an official land border, or they can apply online before they fly. A tourist visa costs US$30 for 15 days, US$50 for 30 days or US$125 for 90 days. In total, you can stay up to 150 days in one visa year (January to December). This guide explains who needs a visa, what to bring, what it costs, where the official forms are, who gets a free visa and what to do if you need more time. It uses information from Nepal's Department of Immigration, the Nepal Tourism Board and the US State Department. Where these sources do not agree, we tell you. Nepal visa quick facts Question Short answer Do I need a visa? Yes, unless you are a citizen of India. Where can I get one? On arrival at listed airports and land borders, online before you travel, or from a Nepali embassy or consulate. What does it cost? US$30 (15 days), US$50 (30 days), US$125 (90 days). How long can I stay in total? Up to 150 days in one visa year (January to December), including extensions. Passport rules At least 6 months of validity after your arrival date, with a blank page for the visa stamp. How much is an extension? US$45 for the minimum 15 days, then US$3 for each extra day. Fine for staying late US$5 per day. Who gets a free visa? Children under 10 (not US citizens), first-time SAARC visitors for up to 30 days, Chinese nationals, and NRN card holders. Who cannot get a visa on arrival? Citizens of 13 countries, and people travelling on refugee travel documents. See the list below. Who needs a visa to enter Nepal? Every foreign visitor needs a tourist visa to enter Nepal, except citizens of India. This applies if you come to trek, climb, visit family, or just stay a few days. If you come for another reason, such as study or work, you still enter on a tourist visa first. After you arrive, you ask the Department of Immigration to change your visa category. There is more on this in the section on other visa types. Three ways to get a Nepal tourist visa 1. Visa on arrival Most visitors use this route. You can get a visa on arrival at Tribhuvan International Airport in Kathmandu, Pokhara International Airport, Gautam Buddha International Airport in Lumbini, and Nepal's land border entry points. Check which airport your flight lands at before you travel. You fill in a form, pay the fee, and an immigration officer issues the visa. You can complete the form online before you travel and bring the printed receipt, or complete it at the airport. The steps are explained below. 2. Online visa (ETA or eVisa) In 2026, the Department of Immigration added an online option called the Electronic Travel Authorisation (ETA), also called an eVisa. You apply on the official website, upload your passport and photo, pay the fee online, and receive the approved visa by email. You then print it and carry it with you. This system is new. A travel news site reported that a Department of Immigration spokesperson gave 17 August 2026 as the date for the full launch, and the Department's website now has a page for the ETA and eVisa. Reports differ on how long approval takes and on what you must show at the airport. We could not confirm one fixed approval time. Read the instructions on the official page, and apply early. 3. Visa from a Nepali embassy or consulate You can also get a tourist visa before you travel from a Nepali embassy or consulate. If you do, you must enter Nepal within six months of the day the visa was issued. Your stay is counted from the day you enter Nepal, not the day the visa was issued. Citizens of the countries in the restricted list below must use this route. Nepal tourist visa fees in 2026 Visa length Fee 15 days US$30 30 days US$50 90 days US$125 These fees are set by the Department of Immigration. You can pay in US dollars or another convertible currency. The Nepal Tourism Board says international credit cards are accepted, and the US State Department says cards may be accepted at the airport. Card machines can fail, so bring enough US dollars in cash as a backup. If you arrive by land, see the border section below for the cash rules that apply to US citizens. Children under 10 and some other groups get a free visa. See the section on free visas. Is the Nepal tourist visa multiple-entry? The Nepal Tourism Board says tourist visas issued at entry points have a multiple re-entry facility, and it lists the 15, 30 and 90-day fees as multiple-entry. However, the Department of Immigration's fee table also has a separate line for an extra US$25 for multiple re-entry under tourist visas. If you plan to leave Nepal and come back during your trip, for example for a side trip to India or Bhutan, ask the officer to confirm that your visa is multiple-entry before you pay. Which visa length should you choose? Plan for delays. The US State Department says bad weather often disrupts domestic flights in Nepal, and it advises leaving extra time before an international flight. A visa that ends close to your departure day leaves you no room. Extending a visa costs more per day than buying a longer visa at the start, and it means a visit to an immigration office. This table compares total costs for some example stays, using the official fees. Planned stay Cheapest option Total cost 15 days or less 15-day visa US$30 30 days 30-day visa US$50 (15-day visa plus a 15-day extension would be US$75) 45 days 30-day visa plus a 15-day extension US$95 60 days 90-day visa US$125 (30-day visa plus a 30-day extension would be US$140) 90 days 90-day visa US$125 If your trip might run past 30 days, the 90-day visa is often the easier choice. You pay one fee and you do not need to go to the immigration office for an extension. What to bring • Passport. It must be valid for at least 6 months after your arrival date. Keep a blank page free for the visa stamp. • Passport-size photo with a light background. The Nepal Tourism Board lists this as part of the visa requirements. The online form asks for a digital photo. • Completed visa form. This is either your printed online receipt or the form you complete at the airport. • Visa fee in US dollars or another convertible currency. Bring cash as well as a card. • Travel details. The online form asks for your travel information and an address where you will stay in Nepal. • Cash declaration, if needed. If you carry more than US$5,000 into or out of Nepal, you must declare it on a customs form. Travel insurance is not listed as a visa document in the sources we checked. The US State Department strongly recommends it, with cover for medical evacuation, if you plan to trek or climb. Application forms and official links Apply only through official government websites. The Department of Immigration sets the visa fee, so you do not need to pay anyone else to submit a form for you. What Link Use it for NepaliPort (online visa services) nepaliport.immigration.gov.np The official online tourist visa form and other visa services.

Nepal Tourism Board Tourist visa page A plain summary of visa rules for tourists. Ministry of Foreign Affairs mofa.gov.np Find a Nepali embassy or consulate in your country. US State Department Nepal travel page Entry rules, advisories and tips for US travellers. Useful for other nationalities too. How visa on arrival works at Kathmandu airport 1. Fill in the form. Complete the online form before you fly and print the receipt, or complete the form at the airport. 2. Pay the fee. Pay at the payment counter and keep the receipt. 3. Go to the immigration desk. Give the officer your passport, your form receipt and your payment receipt. 4. Collect your passport. The officer issues the visa and your passport is stamped. The US State Department warns that getting a visa on arrival may take several hours. Travel guides report that queues are longest in the main trekking seasons, in spring and autumn. If you fill in the online form before you fly, several guides say the receipt is valid for only 15 days, so do not complete it too early. Visa on arrival at land borders You need a visa to enter Nepal by land too. The US State Department notes that officials at some crossings do not stop every foreign visitor. If you do not get an entry stamp from an immigration officer, you may not be allowed to leave Nepal later and may face other problems. Find the immigration office and complete the process, even if nobody asks you to. The State Department lists these land border points where you can buy a tourist visa on arrival. Immigration offices at official land crossings are open 24 hours. • Kakarvitta, Jhapa District (east) • Biratnagar, Morang District (south-east) • Birgunj, Parsa District (central) • Belahiya, Bhairahawa, Rupandehi District (south) • Gadda Chauki, Mahendranagar, Kanchanpur District (west) • Timure, Rasuwa District (north border) US citizens must pay land border visa fees in US cash. Cards and other currencies are not accepted. Bills must be dated 2003 or later and be in good condition, with no tears or heavy wear. Other travellers should also carry clean US dollars in cash. Important: As of the US State Department advisory dated 4 September 2026, travellers are told not to go to the Rasuwagadhi-Timure-Syafrubesi area of Rasuwa District, including the Nepal-China border crossing, after a major flash flood and landslide on 26 August 2026. Check current conditions before planning a route through this area. Who gets a free (gratis) visa? Group What you get Children under 10 Free visa for all nationalities except US citizens. SAARC citizens (except Afghanistan) Free visa for up to 30 days on a first visit in a visa year. Travel guides list Bangladesh, Bhutan, the Maldives, Pakistan and Sri Lanka. A second visit in the same visa year is not covered. Chinese nationals Free tourist visa for up to 150 days in a visa year. Non-Resident Nepali (NRN) card holders Free visa. The card is issued by the Ministry of Foreign Affairs or Nepali missions abroad. Afghan citizens Free visa on arrival only if the Department of Immigration recommends it. Diplomatic and official passport holders The Department lists a free 30-day entry visa for diplomatic and official visits, with the right paperwork from the diplomatic mission. A free visa still needs a form. You complete the same process, but the fee is zero. The "visa year" runs from January to December, so a first visit in December and another in January fall in different visa years. Indian citizens Citizens of India do not need a visa to enter Nepal. You must carry one of these as proof of identity when you enter and leave: • A valid Indian passport • An Election Commission of India voter card • For travellers over 65: a PAN card, driving licence or ration card that shows a photo and age • For travellers under 18: an identity card issued by the school principal The Nepal Tourism Board says the Aadhaar (UID) card is not accepted as a travel document. A Certificate of Registration from the Embassy of India in Kathmandu is also not accepted. Countries that cannot get a visa on arrival The Nepal Tourism Board lists the nationalities below as having no visa on arrival. People from these countries must get a visa from a Nepali embassy or consulate before they travel. Iran was added on 13 March 2026, which raised the total to 13 countries. People travelling on refugee travel documents must also get a visa in advance. Africa Middle East Asia Cameroon Eswatini (Swaziland) Ethiopia Ghana Liberia Nigeria Somalia Zimbabwe Iran Iraq Palestine Syria Afghanistan News reports on the Iran decision say holders of government and diplomatic passports are treated differently. If you hold an official or diplomatic passport, ask the nearest Nepali embassy what applies to you. Because this list has changed before, check the Department of Immigration notice before you book. How to extend your Nepal tourist visa You can extend a tourist visa inside Nepal. The Nepal Tourism Board names the Department of Immigration in Kathmandu (Kalikasthan) and the immigration office in Pokhara. The US State Department adds that offices in Kakarvitta, Birgunj and Belahiya can also extend tourist visas, but only the Kathmandu office can extend every visa type. • Minimum extension: 15 days, for US$45. • Each extra day after that: US$3. • Maximum total stay: 150 days in one visa year (January to December), counting your first visa and all extensions. • How to pay: at the Department of Immigration in cash, in Nepali rupees or US dollars, according to the US State Department. Example: You have a 30-day visa and want 20 more days. You pay US$45 for the first 15 days, plus 5 extra days at US$3, which is US$15. The total is US$60. Bring your passport and your current visa, and ask the office what other papers it needs. Some guides say the extension form is filled in on the NepaliPort website first, so check the portal before you go. Extend before your visa ends. The immigration office at Tribhuvan International Airport cannot extend visas. The US State Department says travellers who reach the airport with an expired visa are sent to the Kathmandu office to pay, and this can take a couple of days. Government offices close on public holidays, so plan ahead. What happens if you overstay? If you stay after your visa ends, you pay a late fine of US$5 per day, on top of the extension fee. The US State Department says that staying after your visa expires can lead to large fines, arrest and a ban on returning, and that staying more than 150 days on a tourist visa can lead to deportation. A person who is deported must travel straight to their home country at their own cost. One more rule: if you replace your passport in Kathmandu, go to the Department of Immigration to move your visa into the new passport. Do not transfer it yourself. The State Department says doing so is a crime in Nepal. Other visa types The tourist visa is the only entry visa. If you plan to work, study, invest or live in Nepal, you enter on a tourist visa and then apply to change the category. The US State Department advises starting at least two months before your tourist visa ends, and says non-tourist visas can take months. Working or volunteering on a tourist visa is not allowed. The Department of Immigration treats volunteering as work. The US State Department says volunteering on a tourist visa can lead to detention, fines, expulsion and a long ban on returning. Visa type Who it is for Fee listed by the Department Transit visa Passengers changing flights in Nepal, up to 24 hours. Proof of transit, such as an air ticket, is needed. US$5 Work visa Foreign nationals with a job in Nepal. Needs a recommendation, a labour permit and a work agreement. US$30, US$50 or US$75 per month, depending on the employer Study visa Students and researchers. Needs a recommendation from the Ministry of Education. From US$30 per month (degree students). US$75 per month (non-degree) Business visa Investors and business owners. US$35 per month, US$400 per year or US$1,000 for five years for smaller investments. Lower fees apply to investments over NPR 100 million Marriage visa Foreigners married to Nepali citizens. US$15 per month Relation visa Foreigners with a direct relation, or a relation by marriage, to Nepali citizens. US$10 per month (direct relation). US$25 per month (relation by marriage) Press visa Journalists and press representatives. US$15 per month NRN visa Non-Resident Nepali card holders. Free Tourist reciprocity visa (US citizens) A 5-year visa with up to 180 days of stay per year. Needs a bank statement showing at least US$10,000, a health insurance certificate and a police report. US$160 Fees from the Department of Immigration fee table, last updated 2 January 2026. Single and multiple re-entry add-ons (US$20 and US$60) apply to most non-tourist visas. Check the Department before you apply. A visa is not a trekking or climbing permit Your visa lets you enter and stay in Nepal. It does not let you enter a national park or a restricted area. The US State Department says some remote areas and national parks need extra permits and fees, and that foreign trekkers must hire a licensed local guide in national parks and protected areas. Climbing and expedition trips usually have their own permits too. Your trekking or climbing company can tell you which permits apply to your route and when to arrange them. Common mistakes that cause trouble • Passport with less than 6 months left. Check the expiry date before you book flights. • A visa that is too short. Weather delays are common. Choose a few spare days. • Relying only on a card. Card machines can fail. Carry US dollars in cash. • Skipping the stamp at a land border. You may have trouble when you try to leave Nepal. • Torn or old US notes at a land border. US citizens need bills dated 2003 or later in good condition. • Waiting until the visa expires to extend. The airport cannot extend it for you. • Filling in the online arrival form too early. Guides say the receipt is valid for 15 days. • Working or volunteering on a tourist visa. This is not allowed. Frequently asked questions Do I need a visa to visit Nepal? Yes, unless you are a citizen of India. All other foreign visitors need a tourist visa. You can get it on arrival, online, or from a Nepali embassy or consulate. How much does a Nepal visa cost in 2026? The tourist visa costs US$30 for 15 days, US$50 for 30 days and US$125 for 90 days. Children under 10 (except US citizens) and some other groups get a free visa. Can I get a Nepal visa on arrival? Yes, at Kathmandu airport, the other airports named by the Nepal Tourism Board, and official land border points. Citizens of 13 countries and people with refugee travel documents cannot. They must get a visa from a Nepali embassy first. Can I apply for a Nepal visa online? Yes. Use the official NepaliPort site or the Department of Immigration's ETA and eVisa page. You can also fill in the visa-on-arrival form online and bring the printed receipt. How long can I stay in Nepal on a tourist visa? Up to 150 days in one visa year (January to December). This includes your first visa and any extensions. How do I extend my Nepal visa? Go to the Department of Immigration in Kalikasthan, Kathmandu, or the Pokhara immigration office before your visa ends. The minimum extension is 15 days for US$45, then US$3 for each extra day. What is the fine for overstaying? The late fine is US$5 per day on top of the extension fee. Long overstays can lead to arrest, deportation and a ban on returning, according to the US State Department. Is the Nepal tourist visa multiple-entry? The Nepal Tourism Board lists the 15, 30 and 90-day tourist visas as multiple-entry. The Department of Immigration fee table also mentions an extra US$25 for multiple re-entry, so ask the officer to confirm before you pay if you plan to leave and return. Does a tourist visa cover trekking or climbing? No. The visa covers entry and stay only. National parks, restricted areas and climbing routes can need separate permits. Ask your trekking or climbing company which ones you need. Do I need a visa if I am only changing flights in Nepal? Nepal has a transit visa for up to 24 hours, listed at US$5. You need proof of transit, such as an air ticket. Check with your airline or the Department of Immigration whether your connection needs one. Can I work or volunteer on a tourist visa? No. Nepal treats volunteering as work. You need the right non-tourist visa first. Before you travel Do three checks before you book. Make sure your passport has at least 6 months left after your arrival day. Choose a visa length with a few spare days. Use only the official government sites for forms and payments.

Acclimatization Guide: How to Acclimatize Safely at High Altitude

Acclimatization is the process your body goes through to adjust to the thinner air at high altitude. You help it along by climbing slowly, taking rest days, and paying attention to how you feel. The first adjustment at a new height usually takes one to three days. There is no way to rush it, and being fit does not replace it. This guide explains what acclimatization is, what changes inside your body, how long it takes, and the habits that make a real difference on a Himalayan trek or climb. It also covers the warning signs of altitude sickness and what to do about them. It is general information, not medical advice. Talk to your own doctor before a high-altitude trip. Key facts at a glance • Altitude illness is linked with travel above about 2,500 m (8,200 ft). It can sometimes happen lower. • Above 3,000 m (9,800 ft), medical guidelines say to raise your sleeping height by no more than 500 m (1,600 ft) per day. • Take one extra night at the same height for every 1,000 m (3,300 ft) of sleeping height you gain. • The height where you sleep matters more than the highest point you reach during the day. • With mild symptoms, do not go higher until they ease. If symptoms get worse, go down. • Fitness, age and past trips do not reliably protect you. What is acclimatization? Acclimatization is your body’s gradual adjustment to a new environment. At high altitude, that means air that gives you less oxygen with every breath. Over days and weeks, your body changes how it breathes, how your blood carries oxygen, and how your tissues use it. The change is temporary. If you go back to low ground and stay there, it fades. It is also different from adaptation. Adaptation is a change in a whole population over many generations. Acclimatization happens inside one person’s lifetime and is not passed on to children. Acclimatize, acclimatization and acclimation: what is the difference? “Acclimatize” is the verb, as in “give your body time to acclimatize”. “Acclimatization” is the noun for the process. In British English you will often see it spelled “acclimatisation”. The meaning is the same. “Acclimation” is a close cousin. Some scientists use it for a response to a single change, such as temperature, usually in a laboratory. They use “acclimatization” for adjustment to a real, natural environment where many things change at once. Some dictionaries treat the two words as the same. For trekkers and climbers, “acclimatization” is the word to use. It is also the word you will find in medical guidelines and on trek itineraries. Why does high altitude affect your body? The air at high altitude has the same share of oxygen as air at sea level, about 21%. What changes is air pressure. Lower pressure means fewer oxygen molecules in each breath. At around 3,650 m (12,000 ft), a breath holds more than a third fewer oxygen molecules than at sea level. Altitude Relative Oxygen Availability (% of Sea-Level Value) Sea level 100% 1,000 m / 3,281 ft 88% 2,500 m / 8,202 ft 73% 3,000 m / 9,843 ft 68% 3,500 m / 11,483 ft 64% 4,000m / 13,123 ft 60% 4,500 m / 14,764 ft 57% 5,000 m / 18,044 ft 53% 5,500 m / 18,044 ft 50% 6,000 m / 19,685 ft 47% 6,500 m / 21,320 ft 44% 7,000 m / 22,966 ft 41% 8,000 m / 26,247 ft 36% 8,848 m / 29,028 ft 33% As altitude increases, atmospheric pressure decreases, so each breath delivers fewer oxygen molecules to your lungs. This makes it harder for your body to get the oxygen it needs, even though oxygen still makes up about 21% of the air. At extreme elevations, such as those encountered during Himalayan mountaineering, the reduced oxygen availability makes proper acclimatization essential. Your body still needs the same amount of oxygen to walk, think and digest food. So it has to work harder to get it. At high altitude, fluid can also leak out of small blood vessels in some people. When that fluid collects in the lungs or the brain, it causes the most dangerous forms of altitude illness. They are covered later in this guide. What changes in your body as you acclimatize? When What happens Minutes to hours You breathe faster and deeper, and your heart beats faster. This brings in more oxygen. The first day or two Your kidneys release more of a hormone called erythropoietin (EPO). EPO tells your body to make more red blood cells. The fluid part of your blood (plasma) also shrinks, so your blood becomes more concentrated. Days to weeks Your body keeps building red blood cells, and the levels of hemoglobin rise. Hemoglobin is the protein in red blood cells that carries oxygen. The full gains in breathing and hemoglobin take weeks. These changes help a lot, but they do not bring your oxygen levels back to what they are at sea level. There is also a limit. Above about 5,600 m (18,400 ft), most people cannot fully acclimatize, and a long stay at that height can harm health. How long does acclimatization take? It depends on the height and on the person. As a general guide, the first adjustment to a given height takes about one to three days. If you then go higher, the process starts again at the new height. Deeper changes, such as a higher red blood cell count, need weeks. People adjust at different speeds. Two people on the same trek can feel very different on the same day. A group should move at the pace of the person who is adjusting more slowly. How to acclimatize safely: 10 habits that matter These habits follow medical guidelines for altitude travel, including those of the Wilderness Medical Society (WMS) and the US CDC Yellow Book. 1. Count your sleeping height, not your daytime height. Your risk depends more on where you sleep than on the highest point you reach in a day. When you read or compare an itinerary, look at the sleeping height for each night. 2. Keep the climb gentle above 3,000 m. Once you are above 3,000 m (9,800 ft), raise your sleeping height by no more than 500 m (1,600 ft) a day. Some guidance suggests 300 to 500 m a day for extra care. 3. Add a rest night every 1,000 m. For every 1,000 m (3,300 ft) you gain in sleeping height, spend one extra night at the same height. A rest day is not a day in bed. Easy walking is fine. The key point is that you do not sleep higher. 4. Start slowly. Guidelines advise against going from low ground straight to a sleeping height above about 2,750 m (9,000 ft) in one day. A flight to a high airstrip such as Lukla, at roughly 2,800 m, puts you near that level within hours. If you fly or drive to height, keep the first 24 hours easy and do not go higher. 5. Climb high, sleep low. Climbers use this saying. During the day you can go higher than where you will sleep, for example on a hike above your rest-day village. Then you come back down to sleep. It lets your body meet a higher level without the strain of sleeping there. 6. Do not go up with symptoms. If you have mild altitude sickness, stay at the same height until you feel better. If symptoms get worse, go down. 7. Avoid alcohol and sleeping pills. Alcohol and sedatives, such as sleeping tablets, slow your breathing during sleep, when you already breathe less. Smoking adds to the load on your body. Skip all three while you gain height. 8. Drink and eat regularly. Dry air and fast breathing make you lose water, so drink often and keep your urine pale. Drinking far more than you need does not protect you and can cause problems of its own. Your appetite may drop at height, but your body still needs fuel. Carbohydrate-rich foods are a common and sensible choice. 9. Move at an easy pace. Heavy effort when you first arrive at a new height does not help. Light activity during the day is better than sleeping, because your breathing slows when you sleep. 10. Tell your guide early. Mention headache, nausea or poor sleep as soon as you notice them. Small problems are easier to handle early. Do not hide symptoms to keep to the schedule. A worked example of the 500 m rule This example only shows the arithmetic. It is not a route plan, and real itineraries depend on where the villages and camps are. Night Sleeping height Gain Note 1 3,000 m — Start of the high section. 2 3,500 m +500 m Within the 500 m limit. 3 4,000 m +500 m You have now gained 1,000 m in sleeping height. 4 4,000 m 0 m Rest night. Easy walking or a short hike higher, then back down to sleep. 5 4,400 m +400 m A smaller step, which is fine. 6 4,800 m +400 m Another rest night is due after about 1,000 m more of gain. Acclimatization on Himalayan treks and climbs • Starting low gives you more time. Medical guidance says that, if possible, you should walk up from a lower start instead of flying or driving to a high point. If a flight to a high airstrip is part of the plan, treat the first day as a rest day. • Rest days sit in hub villages. Namche Bazaar and Dingboche on the Everest Base Camp route, and Manang on the Annapurna Circuit, are well-known places to spend a rest day and take a short hike higher. • Help can be far away. In remote mountain areas, medical care may be hours or days away. This is one more reason to follow the sleeping-height rules and to report symptoms early. • Aid posts exist. The Himalayan Rescue Association (HRA), a non-profit formed in 1973, has run aid posts in Pheriche, at about 4,250 m, and in Manang. Check the HRA website for current details before you rely on them. • Everyone is at risk. People who live at lower heights, including porters, are as likely to get altitude sickness as visitors. • Climbing peaks adds height and difficulty. The same ideas apply on bigger mountains. Teams usually plan acclimatization climbs before a summit attempt. Ask the operator how this is built into the itinerary. Signs of altitude sickness and what to do Altitude illness has three forms. Acute mountain sickness (AMS) is the mildest and the most common. High-altitude pulmonary edema (HAPE) is fluid in the lungs. High-altitude cerebral edema (HACE) is swelling of the brain. HAPE and HACE are rare but can be deadly, and they can happen on their own or together. Condition Common signs What to do Mild AMS Headache, plus one or more of: nausea, dizziness, tiredness, poor appetite, poor sleep. Often starts within the first day (roughly 6 to 24 hours) after reaching a new height. Stop going up. Rest at the same height. Eat and drink. Paracetamol (acetaminophen) or ibuprofen can ease the headache. Tell your guide. Go down if you get worse. Moderate to severe AMS Headache that pain relief does not ease, repeated vomiting, growing weakness, shortness of breath, or clumsy walking and poor balance. Do not go higher. Go down. Even a few hundred metres lower can help. Get medical help. HAPE (fluid in the lungs) Breathless even at rest, tight chest, cough that may bring up white or frothy fluid, unusual tiredness, sometimes bluish lips. Emergency. Go down at once and get medical care. HACE (swelling of the brain) Headache with confusion, odd behavior, loss of balance and coordination, drowsiness, or seeing things that are not there. Emergency. Go down at once with help and get medical care. Guides sometimes check balance with a simple test: walking in a straight line, heel to toe. A person who cannot do this may have a problem with coordination caused by altitude illness. Treat it as a reason to go down. Never leave a person with serious symptoms alone. Going down is the most important treatment. The only real cures for altitude sickness are more time to acclimatize or descent. Medicine and extra oxygen can buy time, but they do not replace going down. What medicines can and cannot do No pill replaces a slow climb. Some people need medicine, and that is a decision for a doctor. • Acetazolamide (often sold as Diamox) is the one medicine shown to help the body acclimatize. A doctor may suggest it for people at higher risk, such as someone who has had altitude sickness before or whose plan includes a fast ascent. It can cause tingling in the fingers and lips and changes in taste. A doctor will check for allergies and other health conditions first. • Dexamethasone is a steroid. It can prevent and treat altitude sickness, but it does not help you acclimatize. It is used on medical advice, often as an emergency treatment. • Pain relief such as paracetamol (acetaminophen) or ibuprofen can ease an altitude headache. It does not cure the cause. • Extra oxygen can ease symptoms, but descent is still the priority. Do not use medicine to climb faster than the schedule allows. Guidelines treat a gradual ascent as the main way to prevent altitude illness. Common myths about acclimatization • Myth: “I’m fit, so I’ll be fine.” Reality: age, sex and fitness do not reliably predict who gets altitude sickness. Doctors who work in the Himalaya say the same. • Myth: “I was fine last time.” Reality: an easy trip in the past is encouraging, but it does not guarantee the next one. • Myth: “A headache is normal, so I’ll push on.” Reality: a mild headache is common, but it is also the main early sign. It is your signal to stop going up and check how you feel. • Myth: “Medicine lets me skip the rest days.” Reality: medicine can lower risk, but a gradual ascent is still the foundation. Before you go: a short checklist • See your doctor, especially if you have heart or lung conditions, are pregnant, or have had altitude sickness before. Ask whether medicine such as acetazolamide makes sense for you. • Read the itinerary night by night. Note the sleeping height, the rest days, and any flights to high airstrips. • Look for spare days in the plan. Extra days give you room to slow down or rest if you need it. • Check that your travel insurance covers the heights you plan to reach and emergency evacuation. Read the policy wording. • Learn the warning signs in this guide, and agree with your guide on what the plan is if someone becomes unwell. Frequently asked questions What is acclimatization at high altitude? It is the process by which your body adjusts to having less oxygen in each breath. Your breathing, heart rate and blood all change over days and weeks. You support the process by climbing slowly, taking rest nights and sleeping lower than the highest point of the day. How long does it take to acclimatize to altitude? The first adjustment to a new height usually takes about one to three days. If you go higher, you start again at the new height. Deeper changes, such as more red blood cells, take weeks. The speed differs from person to person. At what height does altitude become a concern? Medical guidelines link altitude illness with travel above about 2,500 m (8,200 ft). It is less common below that height, but it can happen. Above 3,000 m (9,800 ft), guidelines set clear limits on how fast to gain sleeping height. What is the 500 m rule? Above 3,000 m, raise your sleeping height by no more than 500 m (1,600 ft) per day, and take one extra night at the same height for every 1,000 m (3,300 ft) you gain. Some guidance suggests 300 to 500 m a day for extra care. What does “climb high, sleep low” mean? It means you can go to a higher point during the day, but you come back down to sleep at a lower height. Sleeping height has a bigger effect on your risk than the highest point you reach in daylight. What are the first signs of altitude sickness? A headache is the usual first sign. Nausea, dizziness, tiredness, poor appetite and poor sleep often come with it. These signs usually start within the first day after reaching a new height. Tell your guide, and do not go higher until you feel better. Should I take Diamox? Only if a doctor advises it. Acetazolamide, sold as Diamox, is the one medicine shown to help the body acclimatize. It is not right for everyone, it has side effects, and it does not replace a slow ascent. Speak to your doctor well before the trip. Why do I wake up gasping for air at night at altitude? Above about 3,000 m, many people breathe in an uneven pattern during sleep: a few shallow breaths, then deeper ones, then a short pause. The pause can wake you with a feeling that you cannot breathe. This pattern is common and is not unusual by itself. If you also have a cough, chest tightness or breathlessness when resting, tell your guide straight away, because these can be signs of fluid in the lungs. Is acclimatization the same as acclimation? In everyday speech, people often use the two words in the same way. Scientists sometimes keep “acclimation” for changes to one factor in a lab, and “acclimatization” for adjustment in the natural world. For altitude, use “acclimatization”. Can altitude sickness be fully prevented? No plan removes the risk completely. A slow ascent is the best protection. Sensible sleeping heights, rest nights and early reporting of symptoms lower the chance of serious illness. If it does develop, going down is the main treatment. Plan your acclimatization before you book When you compare treks and climbs, look past the number of days. Read the sleeping height for each night and see where the rest days fall. A well-paced itinerary gives your body a fair chance, and the days you spend at height are more enjoyable when you feel well.
