Langtang is one of the nearest trekking destinations from Kathmandu and is an unparalleled combination of natural beauty and cultural riches. Trekking in this region during spring is amazing as most of the forested hills are painted with blossom of Rhododendron. Langtang lies about 130 km north of the Kathmandu Valley close to the border with Tibet, China. It is Nepal’s first national park, and lies between the Himalayan range to the north, dominated by Langtang Lirung (7,245 m), the highest peak in the area, and smaller peaks to the south – Chimse Danda (ridge), Ganja La pass (5,122 m), Jugal Himal and Dorje Lakpa (6,989 m). 

It also encompasses high altitude lakes – Gosain kunda Lake,  Parvatikunda, Bhairavkunda and Dudhkunda. The forests in the region have temperate and sub-alpine vegetation. Wildlife includes migratory birds, deer, monkeys, tahr and pika. 

The Langtang River passes through the high, gentle Langtang Valley before emptying in a raging torrent into the Bhote Kosi River through a long, narrow defile at the west end of the valley. Whereas the major rivers of Nepal flow south from Tibet cutting through the Himalayan chain, the Langtang River, a major tributary of the Trisuli Ganga, flows east to west, cutting, as it were, across the grain of the country. The Trisuli, or Bhote Kosi as it becomes above Dhunche, forms an important corridor and ancient trade route through the mountains between the Ganesh and Langtang Himal, to Kerong in Tibet
