Within Khentii mountain Range, 82 km to the southwest of Ulaanbaatar city lays a Nature reserve which its name derived from the birch trees (Flus) amply growing in the surrounding mountain forests. The area is specifically reserved for "Takhi”, a wild horse species known as Przewalskis Horse, which was completely extinct in nature by 1990. Mongolian government started organizing takhi reintroduction project in 1992. As a result of successful implementation, there are more than 300 Takhis in the reserve territory today.
Visitors can get all the useful information from the visitor center, by learning the story, viewing pictures and watching video. After that, try your luck and hop on to the vehicle and go look for the Takhis, flourishing in their natural habitat. The best time to observe these rare species from up close is early in the morning or in the evening, during the time when they come down from the mountains to drink water.
