The low peaks of the Gwangju Mountains (including Moraksan) shape the local landscape.
It is bounded to the east by Baegunsan (백운산), Barasan (바라산), the lower slopes of Cheonggyesan (청계산), and Maebongsan (매봉산); to the south by the city of Suwon, to the west by Ansan, Gunpo, and Anyang; and to the north by Gwacheon.
However, the Hwanggujicheon's source is also in Uiwang, and this flows south, eventually emptying into the Yellow Sea at Asan Bay.
Korea Correctional Service operates the Seoul Detention Center in Uiwang.
There are many large corporations, such as Haitai confectionaries, Cheil Industries, Hyundai Rotem, and various trade and logistics companies in Uiwang.
