Best Time for Nalgan Pass Trek — Month-by-Month Guide
A spectacular crossover pass trek.
Seasonal Verdict
When should you go?
A spectacular crossover pass trek. May and June showcase the vibrant spring wildflowers, while September and October offer autumn colors and shepherd migrations. The monsoon brings heavy rain and mud to the approach valleys, making it less ideal but physically accessible.

Editor's Notes
June (shepherd upward migration) and September-October (downward migration) are both excellent times — each gives a different shepherd culture snapshot. The October version adds autumn forest color.
