The Qarhan Playa or Salt Plain, also misleadingly described as Qarhan Lake, is a playa in the Golmud and Dulan counties of Haixi Prefecture, Qinghai, China. Formerly a single unitary lake, it is now an expansive salt flat divided into four greater sections (Dabusun, Big/Small Bieletan, Suli, and N./S. Huoluxun) which contain a number of smaller salt lakes, the largest of which is Dabusun Lake. The area is heavily exploited for its valuable salt, mineral, and rare earth reserves but parts are also protected as a national park and contribute to regional tourism.
