The Chuluut (stony river) is a river flowing down through the valleys of the Khangai Mountains in central Mongolia, and a tributary of the Ideriin gol. It is 415 km long, the width at the mouth into the Ider river is 80 m, the maximum depth is 3 m. It is usually frozen from November to April. Stony river locates at 30 km from Tariat soum of Arkhangai province. Chuluut canyon stretches 25 km in long, above 20 m in high.
The Chuluut river is the westernmost river. It starts off in a narrow, steep but not high basalt canyon that is embedded in a landscape of mountainous steppe. It is a wondrous experience traveling between those sheer walls, which occasionally open up to a view of wooded slopes and rich grazing grounds. The Chuluut is also renowned for its fisheries. Since most of it can´t be accessed unless you are in a canoe there are some good opportunities to enrich the menu with fresh Lennox trout.
