It is a great place to take some gentler day hikes around the marshy areas, which is designated as Ramsar site, an internationally important wetland in 2012.
– Chokhor Valley
The Chokhor Valley has countless small temples and shrines dotting its hillsides. Impossibly pleasant and peaceful pathways guide visitors from one cluster to the next, showcasing the area’s natural beauty.
