Holy Smokes, just look at this picture. There is nothing to do there, nowhere to stay and it's kind of hard to get to but I think once you're there it might be kind of spiritual.
Pangong Tso also known as Pangong Lake, found in Kashmir, is the world’s highest brackish lake at 14,256 feet above sea level. A few years back the government decided to open it to tourists though the lake and its surrounding is under army surveillance. The lake was once divided between Ladakh and Tibet as early as 1684 under the Treaty of Tingmosgang signed between the king of Ladakh, Deldan Namgyal, and the Regent of Tibet. As of today it is shared by India and China. The long and narrow lake stems in the neighbourhood of the famous Chushul mountains. The size of the lake is best inferred from the probable etymology of its name, Pangong, which means extensive concavity. In winter, the lake freezes completely despite being salt water.
