Terelj National park is recognized as a part of the huge Khan Khentii reserve and one of the most popular National Parks of Mongolia. The park’s most spectacular features are its huge granite blocks and cliffs as well as meadows rich in wildflowers. Terelj offers fascinating rock formations against a background of pine-covered mountains, and includes two famous formations named for things they resemble: Turtle Rock (Mongolian: Melkhii Khad) and the Old Man Reading a Book (Praying Lama Rock).

The average elevation is about 1600m, with peaks reaching 2900m. The park is rich in flora and fauna and reminds of beautiful Alpine valleys. The distance from Ulaanbaatar is about 50-70km. Its green meadows carpeted with Edelweiss and a dazzling variety of other wildflowers attract nature lovers. Typical round rock masses determine the look of the overwhelming nature. It is a wonderful hiking and horse riding area. You can visit a nomad’s family or just let yourself be absorbed in the silence of nature. Only the central area, 1km. left and right beside the main road are some small ger camps and a small village. The rest of the area is uninhabited and can be entered only by foot or horseback.

Attractions include Khagiin Khar Lake, a 20m deep glacial lake 80km upstream from the tourist camps, and Yestii Hot Water Springs, natural hot springs 18km further upstream. The park also has a Buddhist monastery that is open to visitors. Park wildlife includes brown bears and over 250 species of birds. The Tuul River flows through the park.
