Season Calendar: Langtang Valley

The Langtang Valley Year

The closest big trek to Kathmandu, and the one where the road matters more than the weather. October to November and March to May are the windows. The valley was rebuilt after the 2015 earthquake, and the teahouses along it are run by the families who did the rebuilding.
