The best time to do Langtang Trek 

Trekking in the Langtang Valley is possible in all 4 seasons. The valley takes on distinct flavors depending on the season. However, the most popular times to visit the Langtang region are in the spring (March to May), right after the freezing winter, and in the autumn (September to November), right after the rainy monsoon.

The pre-monsoon and the post-winter season- spring offers longer and warmer days with clear skies and wonderful scenery perfect for Himalayan trekking trips. The Langtang region in the spring season is filled with a colorful mix of pink, red, and white rhododendron forests. The greenery once again thrives after the dry cold winter. The trails mostly at the higher altitudes can be seen surrounded by aromatic wildflowers.
