It is a lovely lake. But it takes more than an hour to get there (to be fair any site in that area takes an hour or two to get to because Xinjiang is a huge place). Thousands of Chinese tourists are there because it is mentioned in a bunch of Chinese stories which unless you are familiar with do not mean a thing. But the same can be said about most places in Xinjiang. Lakes in the Canadian Rockies are more beautiful and easier to enjoy.
