Langtang National Park

Langtang National Park is a national protected area in north-central Nepal. It was established in 1976 as Nepal's first Himalayan national park and the country's fourth protected area. It covers an area of 1710 km2 in the Nuwakot, Rasuwa and Sindhulpalchok Districts of the central Himalayan region. It contains 26 village communities and includes the Langtang valley. In the north and east it is linked with Qomolangma National Nature Preserve in the Tibet Autonomous Region. The eastern and western boundaries follow the Bhote Koshi and the Trishuli river, respectively.

The Gosainkunda lake is located at an elevation of 4300 m inside the park. The Dorje Lakpa range at 6988 m bisects the park from west–east to south–east. The summit of Langtang Lirung (7245 m) is the highest point in the park.

Langtang National Park is part of the Sacred Himalayan Landscape.

History
In 1970, royal approval designated the establishment of Langtang National Park as the first protected area in the Himalayas. The national park was gazetted in 1976 and extended by a buffer zone of 420 km2 in 1998.

On 31 July 1992, Thai Airways International Flight 311 crashed into the park. The Airbus A310 was on approach to Tribhuvan International Airport in Kathmandu. All 113 people on board were killed.

In April 2015, the village of Langtang, located within the park, was destroyed by an avalanche of ice, rock and mud triggered by the April 2015 Nepal earthquake. At least 215 people were killed. In 2016, the International Astronomical Union named a 9.8km wide crater on Mars after the village, as a tribute. The destruction of the village and other events taking place in Nepal before, during, and after the earthquake are documented in the 2022 Netflix mini-series Aftershock: Everest and the Nepal Earthquake.

Climate
The climate of the park is dominated by the southwest summer monsoon; most of the annual precipitation occurs from June to September, and temperatures vary greatly due to the extreme difference in elevation.

Flora and fauna
Langtang National Park exhibits a high diversity of 14 vegetation types in 18 ecosystem types, ranging from upper tropical forests below 1000 m m altitude to alpine scrub and perennial ice.
