Essential Planning Guide
Prashar Lake Trek — Complete Guide (2026)
Introduction
Prashar Lake is a geological and spiritual enigma. Sitting at 8,900 ft above Mandi, this deep, blue crater lake has a floating island that moves around the surface — no one has been able to explain its origin or the depth of the lake (local divers have failed to find the bottom). The lake is named after Rishi Prashar, who is said to have meditated on its shores. A three-tiered pagoda temple dedicated to him stands at the lake's edge, built in the distinctive Himalayan Kath-Kuni (wood-and-stone) architectural style and dating back to the 13th century. The trek from Baggi village is short and sweet — just 7 km of forest walking — making it one of the easiest and most rewarding treks in Himachal Pradesh. From the lake, the views of the Dhauladhar, Pir Panjal, and Kinnaur-Kailash ranges create a 360-degree visual feast that is hard to forget.

The Floating Mystery
Key point
Prashar Lake's depth has never been measured. Multiple dive attempts have failed. The lake is estimated to be over 100 meters deep at the center — making it one of the deepest crater lakes in the Himalayas.
Key point
The 13th-century pagoda temple is an architectural masterpiece. It's built from a single deodar tree using the Kath-Kuni technique — interlocking wood and stone with zero nails.
