Gorkhi-Terelj National Park is one of the national parks of Mongolia. The Terelj tourist zone has a number of "tourist camps". It is connected with Ulaanbaatar by a paved road. The road comes to the Gorkhiin Davaa pass.
Most of the tourist camps and tourist attractions are before this pass. The road then ends in Terelj settlement, which features small shops and restaurants. Terelj settlement is located in the Terelj Gol river dale, approximately 66 km from Ulan Bator city center. The national park tourist zone is formally Ulan Bator Nalaikh düüreg (district) part, the rest (protected) zone begins to the North from Terelj Gol river and is located in Mongolia's Töv aimag.
A small southern portion of the park is developed for tourists, with restaurants, souvenir shops, horses and camels for rent, and tourist ger camps. However, most of the park is undeveloped and difficult to access. 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.
The park has many rock formations for rock climbers, and includes two famous formations named for things they resemble: Turtle Rock and the Old Man Reading a Book (Praying Lama Rock).
