A portion of the county is occupied by the Yongam wetland, which also crosses into Chorwon. Most of the county's terrain is mountainous, although there a few small expanses of level ground. The Kwangju Mountains and Machonryong Mountains pass through Pyonggang. The region is prone to heavy rains.
The Pyonggang area was known as Puyang hyŏn during the Goguryeo period, and as Kangpyong (강평) under Silla. In the Goryeo Dynasty, it was included in Tongju (동주); in the Joseon Dynasty, it took its modern name.
