Best Time for Junglam Trek — Month-by-Month Guide
Late August to September is the only safe window. Earlier in the summer, the glacial melt makes the river crossings lethal. October brings heavy snow.
Seasonal Verdict
When should you go?
The Jhunglam traverse has one of the narrowest operational windows in the Himalayas. It is entirely dictated by the water levels of the rivers flowing through the deep gorges.
