Kwimyon Rock stands in the Manmulsang (Myriad-shaped Peaks) section of Outer Kumgang in Mt Kumgang, a celebrated mountain in Korea, located in Onjong-ri, Kosong County, Kangwon Province.
This rock of fantastic shape was formed due to the weathering of intrusive rock (granite) in the Mesozoic era. Its pillars and a stone on its top look like the face of a devil, hence its name Kwimyon.
Azalea and other plants grow in the cracks of the rock.
The rock is under conservation as a natural monument as it adds beauty to the scenery of the Outer Kumgang and for its academic significance.
