One of eastern Tibet's most beautiful lakes, Draksum-tso （བྲག་གསུམ་མཚོ, 巴松措, Bāsōng Cuò) is also its most sacred, with strong connections to three towering figures in Tibetan history. It's the soul lake of Gesar of Ling, the semi-mythical king of Tibetan legends and epic poems. Gesar is said to have resided near the lake and spent years in one of the nearby monasteries. Ruins associated with the king can be found on the road up to the lake, as well as around the lake itself.
Draksum-tso was also visited by Guru Rinpoche and, as in many other places, the great sage left signs of his journey on rocks and caves. Finally, the Nyimpgpa lama Sangye Linpa founded the Tsodzong Monastery on a tiny islet just off the southern shore. Today the monastery is one of Kham's most important pilgrimage sites.
