The lake lies at an elevation of 4,718 m, and has a surface area of 1,870 square kilometres. It is the highest salt lake in the world, and largest salt lake in the Tibet Autonomous Region. However, it is not the largest salt lake in geographical historical Tibet. That title used to belong to Qinghai Lake (almost twice the size of Namtso); but since borders were re-drawn in 1965 that lake now lies just over 1,000 km [650 miles] to the north-east in China's Qinghai province.
Namtso has five uninhabited islands of reasonable size, in addition to one or two rocky outcrops. The islands have been used for spiritual retreat by pilgrims who walk over the lake's frozen surface at the end of winter, carrying their food with them. They spend the summer there, unable to return to shore again until the water freezes the following winter. This practice is no longer permitted under the Communist Chinese regime in Tibet.The largest of the islands is in the north-west corner of the lake, and is about 2,100 m long and 800 m wide, rising to just over 100 m in the middle. At its closest point it is about 3.1 km from the shore.
The most remote island is, at its closest, 5.1 km from the shore.The weather at Namtso is subject to abrupt sudden change and snowstorms are very common across the Nyainqêntanglha range.
