The Khukh Lake is 38 km south of the Chuluunhoroot soum center of Dornod aimag. It is 21 km2, with an average depth of 7 meters and a large saline lake. The height of the sea is 552 meters above sea level. The Khukh Lake Depression is the lowest point in Mongolia.
The lowest point in Mongolia is Khokh Nuur (Blue Lake), a medium-sized freshwater lake at 560m altitude. Other than the thrill of standing in the lowest part of the country, there isn't much to keep you here, though the lake has a subtle beauty and you could combine it with an exploration of the Wall of Chinggis Khaan. The lake is also an important migration point for birds and you can spot many waders and shore birds here.
