Caution
Hanle in October
Ladakh, India
October is the last reliable month. Temperatures drop to -5°C to 10°C, and the road from Leh via Nyoma starts getting risky as early snow dusts the passes. The observing conditions are world-class — dry air, no moisture, no light pollution, and 12+ hours of darkness. The Hanle Monastery holds autumn prayers before monks retreat for winter. The plateau is stark and brown, with a beauty that is more Mars than Earth. Homestay options reduce as some close for winter. If you come in October, have a buffer day in case the road back gets tricky. Fill your fuel tank in Nyoma (last station).
The October story
October at Hanle is the astronomical endgame — maximum darkness, minimum moisture, and the winter constellations beginning their rise. Orion clears the eastern horizon by 11 PM with a detail that is almost aggressive — you can see colour differences in the stars with naked eyes. The Orion Nebula (M42) is a green-tinged smear visible in binoculars that resolves into complex gas structures through a telescope. The Pleiades cluster at 4500m reveals 50+ stars where city eyes see 6. Daytime, the plateau is stark brown-gold against deep blue sky — the UV intensity is brutal, wear sunglasses and sunscreen constantly. The monastery's autumn ceremonies include offerings for safe passage through winter. Homestay families start serving heartier meals — thukpa and butter tea become survival food, not novelty. The road back to Leh via Nyoma is still open but carry chains for unexpected ice. Fill fuel in Nyoma. Late October departures should leave early — the passes between Nyoma and Upshi get icy after noon melt refreezes.
