The Orkhon Waterfall water flows for remarkable 1120 km to the North and lies in the historically significant Orkhon Valley, UNESCO World Heritage site. The waterfall formed by combination volcanic eruption and earthquakes some 20000 years ago cascades down from a height 27 meters. The Orkhon, longest river in Mongolia, begins at the state worshipped mountain Suvraga Khairkhan in the Khangai mountain range. The drainage basin of the river is 132835 sq.km. The river is 10-60 m wide to begin with but it becomes 120-150 m around the end and the speed of the river flow decreases. The Orkhon has many species of fish like the pike, Siberian sturgeon, taimen, asian common asp, Siberian grayling, roach etc.
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 tsutgalan waterfall biggest in Mongolia at a height of 26 m. The Orkhon river Valley has been protected since 2006 as a National Park.
