It was established in a general reorganization of local government in 1952. The county's area is primarily mountainous, with the Taebaek and Kwangju ranges both passing through the county. Two basins, the Hoeyang Basin and Changdo Basin, interrupt the rugged terrain. The highest point is Piryubong on Kŭmgangsan. The chief local stream is the Pukhan River, which flows south and east into South Korea. The climate is continental, with extremely cold winters.
