Gosaikunda is an alpine freshwater oligotrophic lake in Nepal’s Langtang national Park, located at an altitude of 4,380 m in the Rasuwa district.
The lake melts and sips down to form the Trishuli river and remains frozen for six months in Winter October to June.
There are 108 lakes in this area, small to medium in size. Gosaikunda is a significant place of interest on the Dhunche-Helambu trekking route. The trek adjoins the famous Langtang Valley trek in the same district.
The trek to Gosaikunda starts in Dhunche village or Syabru besi in the Langtang Himal, or Sundarijal in the Kathmandu valley.
