Best Time for Nanda Devi East Base Camp Trek — Month-by-Month Guide
The Johar Valley approach is brutal.
Seasonal Verdict
When should you go?
The Johar Valley approach is brutal. The trekking window is strictly limited to pre-monsoon and post-monsoon. Attempting this in the monsoon is a severe hazard as landslides actively destroy the trail, while winter seals the valley entirely.
