It's composed of six villages (Ar Bayasgalan, Noyon Khangaï, Terkh, Chandmani, Bayan-Ulaan, Gichgene). It's located in the most mountainous part of the Arkhangai, and many massifs of the Natural Reserve of Noyon Khangai are located inside the sum : Mounts Tsagaan Asgat, Tsakhir Khairkhan, Teel, Terkh and Gichgene. Many rivers cross this isolated and little visited area.
