Pangong Tso is a lake in the Himalayas situated at a height of 4,250 metres (13,900 feet) above mean sea level. The lake is one hundred and thirty four kilometers in length and 2-4 miles in width extending from India to Tibet.

Pangong Tso, one of the largest brackish-water lakes in Asia, is also considered as the largest lake in Ladakh. Owing to the salty water there is no vegetation. Only few species of scrub and herbs grow in the marshy land around the lake. The lake is a breeding ground for a variety of birds. Rare black-necked cranes and other migratory birds are seen near the lake. Among the wildlife species, the kiang is common in this region. The most striking feature of this lake is the changing shades of water, which sometimes sparkles, in varying shades of blue, green, purple, and violet. The crystal clear water of the lake and the green landscape is a real treat for the eyes. The basin is rich in minerals deposits, which accumulate every year by the melting snows from the mountains. In spite of being a salt-water lake, the water of the lake freezes during the winters.

The lake is accessible from Leh, which is well connected by flights from Delhi.
