Kamru Nag is a legendary lake located at a height of 9000 ft above sea level and about 63 km from Mandi town. Spread over half a km the place is an enchanting tourists attraction. A tough trek of 8 km has to be negotiated from Ruhanda (which is 60 km from Mandi) to reach the lake. A wooden temple of Kamru Nag is located on the bank of the lake where thousands of devotees pay their obeisance round the year.
