Khorgo (Mongolian: Хорго) is a dormant volcano in the Taryatu-Chulutu volcanic field in the Tariat district in the Arkhangai Province of Mongolia.

The surrounding park has been a protected area since 1965 as a nature reserve, becoming fully protected in 1994/1997[a] as a national park, in order to safeguard the scenery and the endangered flora and fauna of the area.

[3] A notable geological feature is the solidified lava bubbles, which the locals have named "basalt yurts".

[3] The valleys surrounding the volcano are today populated by small forests of Siberian larch with a variety of flora and fauna.

These ice forms are described as appearing from a distance to be "like large flocks of sheep scattered on the mountain".
