The Kherlen River is one of the longest rivers in Mongolia, originating from the Khentii Mountains and flowing over 1,200 km southeast through the steppe before eventually crossing into China. Historically, it served as a vital freshwater source for nomadic tribes and was strategically important during the Khitan and Mongol empires.
Today, it remains a vital ecosystem supporting nomadic herding, migratory birds, and fish. The riverbanks are ideal for birdwatching, peaceful camping, and exploring the vast grasslands of eastern Mongolia.
