Located between Batang County and Litang County in Ganzi Tibetan Autonomous Prefecture in the west of China's Sichuan Province, Sister Lake is the largest ancient glacier relic on the Qinghai-Tibet Plateau. Lying quietly at the foot of Haizi Mountain against the backdrop of snow-capped mountains and a crystal blue sky, the lake has become one of the must-see destinations for people who travel along the Sichuan-Tibet Highway.
