Trekking in Langtang region is not as well known as trekking in Everest region (east Nepal) or as trekking in Annapurna region (west Nepal). The Langtang region is just north of Kathmandu valley. Hence it is very easily accessible from Kathmandu. Langtang region is declared National Park in 1976. Langtang National Park encloses the catchments of two major river systems' one draining west into the Trishuli River and the other east to the Sunkoshi River. The area extends from 32 km north of Kathmandu to the Nepal China border. Most of the treks are around three important destinations in the region. They are Helambu, Gosaikunda, and Langtang valley.
Helambu: The Helambu area, immediately north of Kathmandu, has many scenic villages inhabited by Sherpa and Tamang.
Gosaikunda: is a glacier lake. There are other glacier lakes. Gosaikunda is the most famous one. It is believed Lord Shiva has created it. Gosaikunda is accessed either from Dhunche or from Sundarijal in the eastern part of Kathmandu Valley. Thousands of Hindu pilgrims visit these lakes during auspicious day of full moon at August called Janai Purnima.
Langtang Valley: The Langtang Valley is reached from the road end at Dhunche or Syabrubesi. It's a long and wide valley at 4000 m altitude, shaped by glaciers. For 10-20 km, the valley floor is almost flat. Dhunche and Melamchi are easily accessed by bus or private vehicle. Alternative routes from Kathmandu are public bus to Sundarijal or Melamchi.
