The Orkhon River, longest river in Mongolia, begins at the state worshipped mountain Suvraga Khairkhan in the Khangai Range. The drainage basin of the river is 132835 sq km. The river is 10-60 m wide to begin with but it becomes 120-150m around the end and the speed of the river flow decreases. On averagely it is 0.5-1.5 m deep but becomes up to 4 m in some places. There are some rapids of 0.5 m in height. Many bigger and smaller rivers flow into the Orkhon: those longer than 100 km are the Tamir, Khugshin Orkhon, Tuul, Kharaa, Eruu and Shar rivers. The Orkhon has many species of fish like the pike, Siberian sturgeon, taimen, Asian common asp, perch, Siberian grayling, roach, Siberian dace, silurus, carp and lake-layer. There are many rocks and boulders around the river as well as some waterfalls like a small waterfall with 4-5 m height and the Ulaan River waterfall - biggest in Mongolia at a height of 20 m. Khan Bayan and Togoo Khairkhan extinct volcanoes are in the south of the Orkhon River and basalt surfaces from the volcanoes cover more than 100 km of an area in the Orkhon River valley. There are many natural sceneries like Uurtiin Tohoi and Uuld red rocks as well as some popular mineral springs like Uurt, Mogoit and Khujirt.
