Prashar Lake is located in the district of Mandi in the state of Himachal Pradesh. Nearby the lake is a three storied pagoda-like temple dedicated to the sage Prashar. The lake is located at a height of 2730 m above sea level. With deep blue waters, the lake is held sacred to the sage Prashar and he is believed to have meditated there. The temple was built in the thirteenth century and legend has it was built by a baby from a single tree. The lake has a floating island in it and it is said to be unclear how deep it is, with a diver not being able to determine its depth. Surrounded by snow-capped peaks and looking down on the fast flowing river Beas, the lake can be approached via Drang.
Mythology says that this lake was formed by Pandawas when they were on their way after Mahabharata yudh with Deity Kamrunag to find best place for their teacher, Dev Kamrunag and Deity liked the isolation of this place so much that he decided to stay here for the rest of his life. On his request, Bheem one of the Pandava brothers formed the lake by pushing his elbow and forearm on the peak of the mountain.
Today people from all faiths come here. As an offering people throw money, silver coins and gold into the water. This place is available for visitors throughout the year except for winter months, from December through March.
