Pangong Lake, is an endorheic lake in the Himalayas situated at a height of about 4,350 m. It is 134 km long and extends from India to China. Approximately 60% of the length of the lake lies in China. The lake is 5 km wide at its broadest point. All together it covers 604 km2. During winter the lake freezes completely, despite being saline water. It is not a part of Indus river basin area and geographically a separate land locked river basin.
The lake is in the process of being identified under the Ramsar Convention as a wetland of international importance. This will be the first trans-boundary wetland in South Asia under the convention.
Pangong Tso can be reached in a five-hour drive from Leh, most of it on a rough and dramatic mountain road. The road crosses the villages of Shey and Gya and traverses the Chang La, where army sentries and a small teahouse greet visitors. The road down from Chang La leads through Tangste and other smaller villages, crossing river called Pagal Naala or "The Crazy Stream". The spectacular lakeside is open during the tourist season, from May to September.
