Helicopter Evacuation in Nepal: How It Works and What It Costs

A helicopter evacuation in Nepal starts with a phone call and ends with a flight to a Kathmandu hospital, and almost everything in between depends on the weather and on who pays. In practice the guide, lodge or agency calls the helicopter company or the insurer's assistance line, a medical decision confirms that flying is needed, and the aircraft flies when the cloud and wind allow, which can be hours or a day later. The cost depends on the route, the aircraft and the flight time. We publish no figure, because our cost data does not cover rescue flights and we will not guess; the useful number is the limit in your policy. This guide explains the steps, the delays, the money questions and the scams to avoid.

This is general information and not medical advice. For symptoms and the descent rule see HAPE and HACE warning signs and altitude sickness basics. For the policy itself, read travel insurance for high-altitude trekking first, because the best time to learn what your cover pays for is before you fly.

The sequence of a rescue

The sequence is usually the same wherever you are. Someone recognises that a trekker is seriously unwell or injured. The guide, or the lodge owner if there is no guide, contacts the agency or the insurer's emergency line and gives the name, policy number, symptoms, position and the nearest landing site. A doctor, either the insurer's or a clinic's, assesses whether a helicopter is justified. The operator assigns an aircraft, the weather is checked, and the aircraft flies to the pick-up point, picks up the patient and sometimes one companion and flies to a hospital, usually in Kathmandu. Throughout, the patient is kept warm, given oxygen if available, and descended on foot or by pack animal if the helicopter is delayed and descent is safe.

Two details trip people up. First, the pick-up point is often not the lodge. The helicopter needs a flat, clear area, and the guide may have to move the patient to a nearby landing site. Second, the patient may be asked to sign consent or payment papers on the spot. It is reasonable to ask what the form says, but not to delay a life-threatening evacuation to argue about it.

Descent first, helicopter second

The CDC Yellow Book makes descent the main response to severe altitude illness, with oxygen and medicines alongside, and notes that for remote groups a portable pressurisation bag can help while waiting to descend. A helicopter is a fast way to descend, not a separate treatment. If a patient can walk or be carried down 300 to 1,000 m safely and quickly, many cases improve; if they cannot, or if the illness is severe, an evacuation is the right call. The Himalayan Rescue Association aid posts at Manang and Pheriche, described in our clinics guide, can help assess the situation in season, and are often the best first stop between the high villages and the trailhead.

Why helicopters are delayed

Mountain flying needs good visibility, manageable wind and daylight. In the Himalaya, mornings are usually clearer and cloud builds from late morning, so rescue flights are often scheduled for early in the day, and a call in the afternoon may be answered the next morning. A storm can ground aircraft for a day or more. Lukla, the gateway to Everest, is a good example: the airstrip is short and its flights are routinely delayed or cancelled by weather, as the Kathmandu to Lukla guide explains. The lesson for trekkers is simple: carry warm layers, water and a headtorch, keep the patient's group together, and do not plan on instant pick-up. A spare day on your itinerary is part of safety, as the buffer days guide argues.

What drives the cost

Without quoting prices, these are the factors that move the bill: the distance from the pick-up point to the hospital; the aircraft, since larger helicopters are costlier than small ones; the altitude, because high pick-ups need more power and sometimes more than one attempt; the number of passengers and the time spent waiting on the ground; and whether the insurer has a contract with the operator or the trekker pays first and claims later. Because these vary by route and season, any single number quoted online is only an example. Our Everest Base Camp page lists insurance covering helicopter evacuation to about 6,000 m as a requirement for the route, and the Annapurna Circuit and Manaslu Circuit pages give their high points so that you can check your own policy.

Who pays, and when

There are three common arrangements. The insurer's assistance company arranges and pays the operator directly, so you pay nothing at the time. Or you pay the operator or the agency first and claim from the insurer afterwards with receipts and medical reports. Or the agency has paid in advance as part of the trip price, with the right to be reimbursed by your insurer. Find out which applies to your policy, and which is written in the booking terms of your agency, before you leave. If you must pay up front, a credit card with a high limit and a plan for who in your family can help are worth more than any other preparation. Always keep every invoice and the medical reports, because the claim will need them.

What your cover must reach on each route

A helicopter is only paid for if the pick-up point is under your policy ceiling, so check the number before the route. From our route pack: Annapurna Base Camp is 4,130 m, Mardi Himal about 4,500 m, Langtang Valley 4,773 m, the Manaslu Circuit 5,106 m (Larkya La), the Annapurna Circuit 5,416 m (Thorong La) and Everest Base Camp 5,545 m (Kala Patthar). Our Everest Base Camp page lists insurance covering helicopter evacuation to about 6,000 m, and the Gokyo Lakes and Everest Three Passes pages list cover for evacuation above 5,000 m. A policy that stops at 4,500 m covers Mardi Himal with no margin and none of the higher routes. The altitude wording, the six points a policy must state and the exclusions are in travel insurance for trekking above 4,500 m, and the premium side is in trekking insurance for Nepal: cost and cover.

What to have ready for the first call

The sequence above starts with a call, and the call goes faster with the facts in one place: the traveller's name, the policy number and the insurer's emergency line, the symptoms and when they started, the position and the nearest landing site, and who is with the patient. Write the emergency numbers and policy details on a card before you leave; rescue and emergency numbers for Nepal treks lists what to carry. If the claim is later questioned, helicopter rescue insurance claims and fraud checks explains what documents to keep. Budget for the rest of the trek too: the Annapurna Circuit cost breakdown and the Manaslu Circuit cost breakdown show which lines insurance does not replace.

Rescue scams and how to avoid them

The UK FCDO notes isolated reports of some trekking guides taking inexperienced trekkers to high altitudes too quickly, and of guides then calling expensive helicopter evacuations from which they take a cut. Most guides and agencies are honest, and a good guide may well save your life by calling a helicopter early. The defences are the same as for any health decision: a slow itinerary with rest days, a registered agency with written terms, and a habit of checking symptoms honestly with your partner. If you feel well and are told you need a helicopter, ask what the symptoms are, ask for a second opinion from an aid post or a clinic if one is close, and ask to speak to the insurer's emergency line. If you really are ill, accept the evacuation; the risk of staying is far greater than the risk of a disputed bill.

What your partners can do

If you are trekking with partners, agree who will make the calls, who holds the policy numbers and who stays with the patient. The trekking partner safety guide sets out roles, signals and an emergency card, and what if your partner cannot continue explains how shared costs are settled when one person is evacuated and the rest continue. Share your policy numbers inside the group before the trek starts, not at the moment of crisis. If you do not yet have a partner, the Everest Base Camp partner page and the Annapurna Circuit one show how to find one.

After the flight

Once the patient is in a hospital, call the insurer again, give the hospital's name and ask what documents they need. Ask for copies of the discharge summary, the invoices and any scans. Tell your family the facts calmly, and tell your partners whether the trek continues. If you are the companion who stayed behind, look after yourself too: a rescue is stressful, and a short rest day before deciding what to do next is sensible. Note names, times and phone numbers, and keep the notes with your policy. If you are on a restricted-area route, tell the agency so that it can tell the permit office if the group changes.

The guide rule and rescue

A licensed guide through a registered agency is required in restricted areas (Department of Immigration) and, under the Nepal Tourism Board rule of April 2023, in national parks and conservation areas, where 2026 operator reports say checkpoints enforce it in Annapurna and Langtang but not in Khumbu (checked 19 October 2026). A guide with a phone, a radio or a satellite messenger is the quickest route to a rescue, which is one practical reason to hire one even where the rule is reported not to be checked. See the guide rule by region and the Everest region page for more, and the altitude and health hub for related guides.
