Helicopters on this sector start at first light, when winds are calm and cloud lies low in the valleys. Pilgrims are weighed with their bags at Simikot and assigned to sorties of four or five, depending on the aircraft, temperature and altitude. Thinner air at Hilsa reduces lifting power, so loads are kept light, and a large group may need several rotations over a couple of hours.
The flight follows the Humla Karnali north through gorges, past terraced villages and pine slopes that give way to bare rock. Landing at Hilsa takes a few minutes, and the helicopter turns around quickly for the next load. Arrivals wait at the helipad or a nearby lodge until the whole group is through.
By late morning, wind and cloud often build and flights stop. A missed slot can mean waiting until the next day in Simikot, which is why itineraries carry a buffer. Anyone with heart or lung conditions, or who is pregnant, should not take part in high-altitude helicopter travel; get medical advice before booking.

Questions travellers ask
How long is the helicopter flight from Simikot to Hilsa?
About 20–30 minutes each way. Helicopters carry four or five passengers per sortie, so a group of fifteen or twenty needs several rotations, spread over a morning. Flights run mainly early in the day before wind and cloud build up in the gorges.
What is the baggage limit on the Simikot–Hilsa helicopter?
Operators usually allow about 10–15 kg per person including hand luggage, weighed with the passenger. Limits are set by the operator on the day according to weather and altitude. Extra luggage stays in Nepalgunj or Simikot. Pack a soft duffel with only what you need for Tibet.
What happens if the Hilsa helicopter cannot fly?
The group waits in Simikot or Hilsa until conditions improve, often the next morning. Our heli-route itineraries include a spare day for this. If delays run longer, the Tibet section is shortened or extra nights are added, and we explain any additional costs at the time.
