Best Time for Annapurna Base Camp Trek — Month-by-Month Guide
Outstanding in spring (March-May) for spectacular forest blooms, and autumn (September-November) for crystal clear skies. Views of surrounding peaks are cleanest and sharpest during these stable windows.
Seasonal Verdict
When should you go?
Annapurna Base Camp (ABC) is a classic teahouse trek in Nepal. The primary seasons are Spring (March-May) for spectacular rhododendron blooms and Autumn (Sept-Nov) for the clearest mountain views. Monsoon brings heavy rain and leeches, while Winter brings extreme cold and avalanche risks in the Modi Khola gorge.
