Also known as the Lake Conggo, it is in Xoka District in Gongbogyamda County with an elevation of more than 4,000 meters. It is more than 300 kilometers away from Lhasa. In the middle of the lake there is an ancient temple of the Rnyingma Sect built in the 17th century.

During the Walking Around the Lake Festival on the 15th of the fourth month of the Tibetan calendar, Buddhist believers from Nyingchi and other places come to walk around the lake.

(Holiday resort by the Lake Pagsum Co is the first of its kind in Tibet and is in individual- and villa-typed architectural style.)
