Langtang National Park is the fourth national park in Nepal and was established in 1976 as the first Himalayan national park. The protected area exceeds an altitudinal range of 6,450 m (21,160 ft) and covers an area of 1,710 km (660 sq mi) in the Nuwakot, Rasuwa and Sindhulpalchok districts of the central Himalayan region encompassing 26 Village Development Committees.
The northern and eastern border of the national park coincide with the international border to the Tibet Autonomous Region. The western boundary follows the rivers Bhote Kosi and Trisuli. The southern border lies 32 km (20 mi) north of the Kathmandu Valley. The rugged summits of Langtang Lirung with an elevation of 7,227 m (23,711 ft) and Dorje Lakpa (6,966 m (22,854 ft)) are included in the national park as well as the high altitude sacred lake of Gosainkunda.
