Khorgo Mountain is a dead volcano which lies on the west of Tariat village of Arkhangai province. Khorgo crater, situated at an altitude of 2.210 meters with a diameter of 20 meters and depth of 70 to 80 meters, is the most interesting at all. About 8000 years ago volcanic lava flooded the valleys nearby which are covered today with small forests of Sibirian larch and a great variety of berries and flowers. You can climb up to the rim of the crater for some fabulous views. There are steps uo to the crater from the west side.
