Pangong Tso is about five hours drive from Leh in Ladakh region of Jammu & Kashmir. The route passes through beautiful Ladakh countryside, over Chang La, the third highest motorable mountain pass (5289 m) in the world. The first glimpse of the serene, bright blue waters and rocky lakeshore remains etched in the memory of tourists. There is a narrow ramp-like formation of land running into the lake which is also a favourite with tourists. Situated at a height of about 13,900 ft, the name Pangong is a derivative of the Tibetan word Banggong Co meaning "long, narrow, enchanted lake". One third of the lake is in India while the remaining two thirds lies in Tibet, which is controlled by China. Majority of the streams which fill the lake are located on the Tibetan side. During winter the lake freezes completely, despite being saline water. The salt water lake does not support vegetation or aquatic life except for some small crustaceans. However, there are lots of water birds. The lake acts as an important breeding ground for a large variety of migratory birds like Brahmani Ducks, Rare black necked cranes and Seagulls. One can also spot Ladakhi Marmots, the rodent-like creatures which can grow up to the size of a small dog. Pangong Tso lies on the Sino-Indian Line of Actual Control and hence requires an Inner Line Permit. Most of the lake is in Chinese-controlled territory. Owing to Pangong's proximity to the border, tourists are only allowed to visit the lake upto the Spangmik village. For the hardcore adventure lovers, there is a camping site on the shore of Pangong. But do remember that the weather tends to get harsh after dusk. The place is a photographers' delight and camping is the only option if you wish to see the sunset and the sunrise.
