The Langtang Valley Trek in Nepal is amazing walking in the Langtang National Park, jungle covered valleys at lower elevations, and wide, barren alpine valleys once the trail climbs to Langtang Village. It is best to Trek Langtang Valley in October and November, after the monsoons have ended and before winter sets in. The sky is clear, and the leaves are colorful, providing a photogenic background. March to May is also a good time to visit as the wildflowers and rhododendrons are blooming.
The Langtang Valley Trek in Nepal was severely impacted by the 2015 Nepal earthquake. The village of Langtang was completely destroyed by an avalanche in which several hundred residents and foreigners perished. Though most of the trail has been repaired, the scars are still visible in the form of damaged bridges, abandoned villages and crumbling structures.
