Gosaikunda

The Gosaikunda lake is located an altitude of about 4360m. This is considered on the Nepal’s most sought after pilgrimage sites. It is surrounded by mountains on almost all sides and a great ensemble of nine other lakes accompany the Goisaikunda. Every year during Janai Purnima in August, hundreds of Hindu pilgrims visit for a holy bath in the lake. The large rock at the center of the lake is said to be the remains of a Shiva shrine and it is also claimed that channel carries water from the lake directly to the tank at the Kumbheshwar Temple in Patan in the Kathmandu valley.
You can trek for about 4 days to reach Gosaikunda. It is best done after some acclimatizing in Langtang or Helambu. From either Dhunche or Syabru, the trails generally ascend across forests. On the way you will also come across a monastery and a cheese factory. Above here, the trail climbs through tall fir stands before emerging above the tree line for increasingly panoramic views of the high peaks and finally entering the barren upper reaches of the Trishuli river, where glacial moraines and rockslides have left a string of half a dozen lakes (kund).
