Prashar Lake lies 49 km north of Mandi, Himachal Pradesh, India, with 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 regarded to have meditated there. Surrounded by snow-capped peaks and looking down on the fast flowing river Beas, the lake can be approached via Drang. 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
