Prashar lake is a beautiful and small blue water lake located around 50 km away from Mandi town in Prashar forest range.
The three tiered Pagoda like temple nearby the lake is dedicated to sage Prashar. The lake is located at 2730 meters. There is big camping ground near the lake. There is small island in the lake which changes its position. The lake has religious significance and needs to be respected according to local traditions. It had become a good trekking spot lately because of its proximity to plains as well as peaceful and breathtaking views.
There is a motorable road all the way up to the lake. You can take the 7.45 AM bus from Mandi which reaches Prashar lake (via Kataula and Bagi) at around 11.15 AM and returns from Prashar lake at 1.15 PM reaching Mandi at around 4.15 PM daily. Buses do not ply in peak winters when it snows as the road is not in good condition. You can also take a bus till Bagi and trek through the forest.
Prashar Lake trek is a popular weekend trek among the Himalaya lovers. Generally the trek can be done in 2 days with overnight camping on first day night at bautiful camping site beside the lake. You can carry your own tent and pitch there. Else you can take help from guide or other organizers. You can start the trek from Bagi village (around 26 km from Mandi via Kataula).
