Ulaan Tsutgalan Waterfall
The Orkhon River (/ˈɔːrkɒn/ OR-kon) is the longest river in Mongolia. It rises in the Khangai Mountains in the Tsenkher sum of Arkhangai aimag at the foot of the Suvraga Khairkhan mountain. From there, it crosses the border into Övörkhangai aimag and follows the upper Orkhon valley in an eastern direction until it reaches Kharkhorin. On this stretch, very close to the Orkhon, the Ulaan Tsutgalan river features a waterfall, ten metres (33 ft) wide and twenty metres (66 ft) high, which is a popular destination for tourists.
