réponse rapide
The safest season for Humla trekking is late September to late October, when the Nyalu La pass at 4,990 metres is snow-free and Simikot flights run on schedule. Spring from late April to mid-May is a secondary window. Avoid June to August monsoon and November to March winter.
Répartition détaillée
The Limi Valley Trek in Humla district of far western Nepal runs 14 to 18 days from Simikot at 2,950 metres to the villages of Til, Halji, and Jang at 3,700 to 4,000 metres, crossing the Nyalu La at 4,990 metres. The route follows an ancient salt trade route to Tibet and is one of the most remote teahouse treks in Nepal.
Simikot is reachable only by air from Nepalgunj or by 7 day walk from Surkhet. The airport sits at 2,950 metres on a ridge and is famously weather-sensitive. Flights cancel on average 30 percent of days in shoulder seasons and 50 percent in winter.
The Nyalu La pass at 4,990 metres is the route crux. It holds snow from November to April and can be impassable after fresh falls. The pass is non-technical in clear weather but route-finding in fog or fresh snow is dangerous without a guide.

Qu'est-ce qui affecte la réponse
Pass snow cover is the first factor. Nyalu La clears of snow by mid-September and stays walkable until early November. May is a short spring window before June cloud builds. November to April has snow on the pass and most guides refuse to cross.
Flight reliability is the second factor. Simikot flights need clear weather and low wind. October sees 80 percent flight success. May sees 70 percent. June to August sees 50 percent with monsoon cloud. Winter sees 40 percent with snow on the runway.
Village lodge availability is the third factor. Til, Halji, and Jang have 4 family lodges total. October books 60 days ahead. May is easier to book. Winter lodges close.
Conseils pour la réservation
Book October treks 60 to 90 days ahead. Nepalgunj and Simikot flights fill by August. Limi Valley permits take 7 to 14 days to issue through a Kathmandu operator.
Plan 2 buffer days at the end of the trek for Simikot flight delays. Trekkers who book international flights home the day after trek end miss them 20 percent of the time in October.
Carry cash for Nepalgunj hotels. The transit city has limited card payment and 2 to 3 day waits for Simikot flights are common.
Comparaison avec les alternatives
Compared with the Kailash Mansarovar route from Humla, the Limi Valley Trek stays inside Nepal and avoids the Tibet border complications. Kailash needs Chinese visa and group permit, which adds $1,500 to $2,000.
Compared with Upper Dolpo, Limi has fewer camping nights and a clearer autumn window. Upper Dolpo also walks in June, but Limi is more reliably clear in October.
Erreurs courantes à éviter
Booking October Simikot flights with no buffer. Simikot cancels 20 percent of October flights due to morning cloud. Build 2 buffer days into your itinerary.
Crossing Nyalu La in early November after fresh snow. The pass holds hidden crevasses near the top. Wait 2 days for snow to settle or turn back.
Treating June as a Humla trekking month. June monsoon cloud blocks Simikot flights 50 percent of days and snows on the pass. June treks have a 30 percent abort rate.
FAQ
Can I trek Humla in winter?
Not recommended. The Nyalu La is snow-covered from November to April. Simikot flights cancel 60 percent of winter days. Some trekkers walk lower sections but the Limi Valley loop is not safe.
What if my Simikot flight cancels?
Rebook for the next morning. Build 2 buffer days into your itinerary. If delays extend beyond 3 days, operators can charter a helicopter at $3,500 to $5,000 split among the group.
Is the Nyalu La pass technical?
No, in clear weather. The pass is a 600 metre boulder and scree ascent. In fresh snow it becomes crevassed. Guides carry rope but most parties wait for snow to settle.
Is spring or autumn better for Humla?
Autumn. October has clearer skies, warmer days, and better flight reliability. May is a secondary window with cooler nights and higher flight cancellation risk.
Do I need a guide for Humla?
Yes. The Humla restricted-area permit requires a licensed guide. Independent trekking is illegal. Local guides also handle language, lodge booking, and pass crossing.
somm
October is the safest Humla trekking season with clear weather, open Nyalu La pass, and 80 percent Simikot flight reliability. May is a secondary window. Avoid June to August monsoon and November to March winter snow.
conclusion
For 2027, plan Limi Valley and Humla trekking for late September to late October. Build 2 buffer days for Simikot flights, book 60 to 90 days ahead, and carry cash for Nepalgunj transit. May is a backup if October is full. Avoid all other months.
