Langtang National Park was established as Nepal’s first Himalayan national park and the country’s fourth protected area in 1976. Langtang occupies 1,710 square meters. Langtang is one of Nepal’s most stunning national parks. It is the most easily accessible highland sanctuary in the country and is located north of Kathmandu. Lantang reflects the strong spectrum of vegetation types between 1000 m and 7245 m along the altitude scale. By walking three days from the Bhotekoshi River to Langsisa, landscapes created by the complex topography and geological settings and altitude can be experienced. The rich vegetation of the park is characterized by the forest of Sal in the southern part of the park and is gradually taken over by the hill forest consisting of Chirpine , Rhododendron and Nepalese alder.
