The Best Time to Visit Simikot
Spring and autumn for settled weather, summer in the rain-shadow upper valleys, and winter snow and flight delays.
The best time to visit Simikot and Humla is late spring (May–June) and autumn (late September–October), when the weather is most settled and flights into the district are most reliable. Because the upper valleys sit partly in the Himalayan rain shadow, the summer monsoon is also viable here — unlike much of Nepal — while winter brings heavy snow, blocked passes and frequent flight cancellations.
Spring (March–June)
Spring is one of the prime windows. By late spring (May–June) the high passes have largely cleared of winter snow, days are warm, skies are often clear, and the trails to the Limi Valley and Hilsa are open. This also coincides with the start of the Mount Kailash pilgrimage season, so flights and lodges in Simikot get busy. Early spring can still see snow lingering on the highest passes, so May onward is the safer bet for the full Limi loop.
Summer monsoon (June–September)
Here Humla differs from most of Nepal. The upper valleys, including Limi, lie in the rain shadow behind the main range and stay far drier than the monsoon-soaked south. Lower trails near Simikot can be wet, muddy and leechy, and flights are less dependable in cloud, but the high trans-Himalayan country is often perfectly trekkable. This is also the peak Kailash pilgrimage period, particularly around the Saga Dawa festival, so the Hilsa route is at its busiest.
Autumn (late September–November)
Autumn is the other classic window. After the monsoon clears, the air is crisp, visibility is excellent, and the high passes on the Limi Valley trek are open before winter snow returns. Late September into October is ideal; by November the cold deepens and the higher routes begin to close. Combined with stable flying weather, this makes autumn a favourite for trekkers.
Winter (December–February)
Winter is best avoided by most visitors. Heavy snow blocks the high passes, bitter cold settles over the district, many villages empty out as families move lower, and flights are frequently cancelled for days at a time. The Limi and Kailash routes are effectively closed, and even reaching Simikot becomes a gamble against the weather.

Frequently asked questions
When is the best time to visit Simikot?+
Late spring (May–June) and autumn (late September–October) give the most settled weather and the most reliable flights into Simikot. These windows offer warm days, clear skies and open passes for the Limi Valley and Hilsa treks, which is why most expeditions are timed for them.
Can you visit Humla in the monsoon?+
Yes, more than much of Nepal. The upper Humla valleys, including Limi, lie partly in the Himalayan rain shadow, so they stay drier than the south during the summer monsoon. Lower trails can still be wet and leechy, and flights are less reliable, but the high country is often trekkable.
Is winter a good time for Simikot?+
Generally no. Winter brings heavy snow, blocked passes, bitter cold and frequent flight cancellations across Humla, and many high villages empty out. Travel is difficult and the Limi and Kailash routes are effectively closed, so winter is best avoided by most visitors.
When does the Kailash pilgrimage season run via Simikot?+
The Mount Kailash pilgrimage via Simikot and Hilsa mainly runs from around May to September, peaking in summer around the Saga Dawa festival. This overlaps with Humla's drier rain-shadow window, but it also makes flights and lodges busy, so book well in advance.
