Though popular in India due to its appearance in the Bollywood movie 3 idiots it still is hardly the compelling reason to visit the lake. The salty lake, which lies in both in India and China where majority of the lake lies, is 130kms long and 5kms wide. The extraordinary reflection of the blue skies is something that will take your breath away. PangongTso is at an elevation of 4300m, 150 kms east of Leh. It is recommended to atleast spend a night at its shore in available camps or homestays. The route to Pangong passes through Changla pass, amongst the highest passes in the world.
Even higher than PangongTso, Tsomoriri is at an elevation of over 4500m about 240 kms southeast of Leh. The lake is 20kms long and 3kms wide and its water is brackish.The lake is a part of a Wetland Conservation Reserve because of its rich flora and fauna. The famous birds and animals include Kiang (fames Tibetan Ass), bar-headed geese, black-necked cranes, and if lucky snow leopards and tibetan wolf. The villagers still extract salt from its waters.
The smallest of the lot is the most unexplored lake called Tso-kar, which lies on the route to Tsomoriri. It is a fresh water lake with a lot of birds. Reservations would be best if you stay in Tsomoriri camps or Chumathang (60 kms from the lake).
