Taken in August of 2016 at Pangong Tso in Ladakh

With each change in cloud and sky, Pangong Tso looks like a different lake.

Pangong Tso is a long, narrow lake that crosses the border between India and China. By length, the majority of the lake falls in China, but these photos were all taken on the Indian side of the border.

It’s actually substantially higher than Lake Titicaca in Peru, which claims the title of highest navigable lake in the world. Pangong Tso is 4,350 m (14,280 ft) while Titicaca is 3810 m (12,500 ft.)

Don’t ask me what constitutes “navigable.” My wife and I tried to figure that out when we visited Titicaca several years ago. We didn’t see anything bigger than the boat we were on–nothing that would be called a ship. Of course, we saw not so much as an inner tube on Pangong Tso, and the fact that it’s so narrow in places may mean that a boat would have to have an exceedingly shallow draft to make it down the lake’s length. That is if one could travel the lake’s length without trigger happy Chinese or Indian military forces freaking out and blowing your boat out of the water.
