It's hard to say if the Changtang region is actually a "tourist attraction" - that moniker would only fit if you happen to be a wolrd class athlete, biologist, relative of a nomad or hopelessly lost.
This region of Tibet is larger than germany and is know for sand, thunder, brackish, lifeless lakes and some of the coldest winters in the world. many species of hardy animals live here though and rest assured that when Armageddon hits, these guys will make it to the other side.
Yak, antelope and mules share space with many different species of birds that rest on th lakes as well as predators such as the famous snow leopard as well as Tibetan bears and wolves.
The nomads that live here have a routine that has existed for as long as they can remember and the contact they have with teh "civilized" world is mostly through trade for needful things. naturally, the world is encroaching a bit, but this is one of the only regions on earth where the nomadic way of life will be allowed to go on as usual, because farmers can't grow anything here, busiunesmen haven't found anything to exploit yet and politicians do not see the nomads as a large enough faction for them to exert control over. So far so good.
