Everything you need to know about helicopter performance limits, acclimatization parameters, weight restrictions, and booking schedules.
01 / Langtang Valley Helicopter Tour
The tour lands at Kyanjin Gompa, which lies at 3,830 meters – high enough for mild hypoxic symptoms. We limit the stopover to 45 minutes to prevent AMS from setting in, and our helicopters are equipped with Safran-certified medical oxygen cylinders just in case.
Yes. All necessary permits for Langtang National Park, airport departure taxes, and local aviation registrations are fully managed by our operations team and included in your charter invoice.
The cheese factory typically operates during the milk-producing months, from spring (April) to early winter (November). During this period you can visit, observe cheese-making, and buy fresh yak cheese directly.
The primary season is spring (March to May) for clear morning skies and blooming rhododendrons, and autumn (September to December) for the absolute sharpest views of the high glaciers and clear air.
To operate safely inside high alpine zones, helicopters must balance payload limits. An average weight limit of 85–90kg per passenger applies. If your weight is significantly above this, please let us know so we can adjust fuel ratios or payload calculations.
02 / Gosaikunda Helicopter Tour
Gosaikunda is situated at 4,380 meters. Because we ascend rapidly, we strictly limit ground time to 30 minutes to prevent altitude sickness from setting in. We also carry Safran-certified medical oxygen cylinders on board in case any passenger experiences mild hypoxic symptoms.
Safety is our absolute priority. Himalayan weather fluctuates. If pilots determine that visibility or wind speeds exceed visual flight safety parameters, the flight will be postponed. Passengers are offered a full refund or a free reschedule window.
Even in spring/autumn, high alpine temperatures at 4,380m can be freezing, especially with wind chill. We recommend wearing windproof down jackets, thermal layers, sunglasses (critical to block snow glare), warm gloves, and sturdy closed-toe shoes.
Early mornings (06:30 AM to 10:00 AM) offer the most stable atmospheric conditions in the Himalayas. As the sun heats up the valleys, hot air rises, creating strong wind drafts, thermals, and clouds that compromise safety and ride comfort later in the day.
Yes. Since there is zero trekking required and ground time is only 30 minutes, children and elderly passengers of average physical fitness can safely participate. However, we advise passengers with severe chronic respiratory or cardiac conditions to consult their physician before booking.
03 / Bookings & Operations
Submit the Inquire Charter form on the homepage or visit our Contact page to reach our Kathmandu flight operations deck. Our team confirms aircraft availability, weather windows, and pricing, then issues an invoice. A deposit secures your date and the balance is due before departure.
All high-altitude Langtang charters depart from the domestic apron of Tribhuvan International Airport in the early morning windows (roughly 06:30–07:30 AM) to take advantage of stable air and clear morning skies. Exact times are confirmed ahead of your booking.
We recommend booking 2–3 weeks ahead during peak seasons (spring and autumn). Last-minute private charters are occasionally possible if the aircraft and pilot are available, but advance booking guarantees your preferred date and departure slot.
Yes. In addition to private charter flights, we run daily group-joining seats during the spring and autumn seasons. These are seat-basis bookings shared with other passengers and are the most economical way to fly to Kyanjin Gompa or Gosaikunda.
04 / Safety & Altitude
Our fleet is built around the Airbus H125 (AS350 B3e), a high-performance single-engine helicopter renowned for its outstanding high-altitude capabilities. It is equipped with Safran medical-certified oxygen systems and flown by experienced high-altitude pilots.
Travel insurance is strongly recommended and should cover helicopter/high-altitude activities and emergency evacuation. Our operation carries full passenger liability and aviation insurance, but personal travel insurance protects you against trip interruption and other non-flight risks.
