There are two permits required to enter the park, a park permit and a border permit. The Park Permit is available at the Visitor Information Center in Ölgii or at one of the Park Ranger Stations near Tavan Bogd Mountains and on the Hovd River south of Tsengel (on the way to the lakes). Each person should have one, which is 3000T for foreigners and 1500T for Mongolians. All visitors must go to a Ranger Station upon entering the park. There are 2 near Tavan Bogd in each of the 2 valleys approaching the mountain, plus an additional one in Syrgil between the lakes (after the Hovd River Ranger Station).

The Border Permits are required for going within 100 km of an international border of Mongolia. Permits for the Chinese border zone are available at the Border Patrol Office in Ölgii (near the river, 1 km west of the bridge). Permits for the Russian border are only available in Tsaagannuur village, near the Russian border crossing and 70 km north of Ölgii. The Russian border permit is required if going north of Pontuninii Glacier and to Khuiten Uul Mountain. It may also be required if rivers near Tsengel are too high to cross and require taking a northern route to the mountains. The Russian permit is not required if you enter the park near the lakes.
