Gosaikunda, also spelled Gosainkunda, is an alpine freshwater oligotrophic lake in Nepal's Langtang National Park, located at an elevation of 4,380 m (14,370 ft) in the Rasuwa District with a surface area of 13.8 ha (34 acres).

[3] The lake melts to form the Trishuli River; it remains frozen for six months in the winter October to June.

Its waters are considered holy and of particular significance during the Gangadashahara and the Janai Purnima festivals when thousands of pilgrims from Nepal and India visit the area.

[2] According to legend, the spring that feeds the pond in the Kumbheshwar temple complex in Patan is connected to Gosaikunda.

Therefore, those who cannot make the long journey to the lake, visit Kumbeshwar Pokhari instead.
