Best Time for Animal Pass Trek — Month-by-Month Guide
September is the ultimate window, offering crystal clear skies and stable weather, though August provides incredibly dramatic monsoon landscapes.
Seasonal Verdict
When should you go?
The optimum trekking window is during the summer and monsoon months (June to September). The monsoon brings heavy rain to the lower valleys but keeps the high-altitude meadows spectacularly lush.
