Just 2 kms from Batal towards Kunzum La Pass is a diversion to Chandra taal lake. The lake is 12 kms from that diversion. The Forest Department banned camping next to the lake in the year 2010 to keep it clean and a barricade has been put up 2 kms before the lake to avoid pollution at the lake. This is the approved camping area and you can find accommodation here in some fixed camps during the season. Another route to reach the lake is to hike from Kunzum La Pass (4551 meters).
It is forbidden to camp next to the lake as Dhankar lake acts as a source of water for Dhankar village. This lake is also the kick off point for the Spiti Left Bank trek.
