The Tuul River rises from the Baga Khentii Range, a branch of the Khentii Range. The river runs along valleys with lots of boulders, cliffs and wicker groves and it passes along the north side of Bogd Khan Mountain. The Tuul River is the biggest river flowing into the Orkhon River. Approximately 20 rivers flow into Tuul River such as the Zaan, Terelj, Uliastai, Selbe, Gorkhi, Khar Buh, Tama, Khuirkhree and Turgen rivers. Among the biggest are the Galttai (50 km) Terelj (78 km) and Khar Bukh (159) rivers. The drainage basin of the Tuul river is 50400 sq km and it equals 38 percent of the total drainage basin of the Orkhon River. The water table is changeable because the river is mainly fed by rains in summers and autumns. The Tuul River starts to freeze at the end of October and keeps ice cover for 138 to 164 days. Rafts were used to transport woods on the river in 1950s. According to scientists, water levels of the river was much higher than now. The Tuul River has worn out some edges and branches of mountains. This process has created lots of hills in the Tuul River valley, such as Zaisan hill, Aldar hill, Bayart hill, Ishgen hill, Bujin hill, Lun hill and Ochir hill. The Tuul River is one of the three historic rivers: in the Mongolian Secret History it talks about many events held in the Tuul River valley. Moreover, there are many historical sites and memorials such as the Tuuliin Khar Tun Palace of Ban Khan, the tombs in Dadart Mountain, White Building of Tsogt, ruins of Khar Bukh, ruins of Taliin Ulaan, ruins of Chin Tolgoi, memorials of Ungut, ruins of Davaatseren, memorials in Morin Tolgoi and tombs in Khairkhan Mountain.
