Gosaikunda is one of the holiest lake of Nepal located in Langtang National Park of Rasuwa district at the altitude of 4,380m. It is one of the popular 5 to 7 days trekking route of Dhunche- Gosaikunda- Sundarijal / Helabu. 
According to Hindu religion, the lake is believed to have originated from the digging of the land by the Trishul (holy three pointed sword) of lord Shiva after he drank the poison from Samundramanthan and desperately wanted cold water to quench the overwhelming heat of the poison.
