Geography

Like much of the Korean peninsula, Uiwang City is surrounded by mountains to the east and flat lands to the west. The Eastern Mountain Range heads off from Cheonggye Mountain to the north and is continued by a chain of mountains and hills including Baekwoon Mountain(白雲山,567m), Guksabong( 國思峰, 540m), and Bora Mountain(428m) towards the south. The areas to the west and south of Uiwang City are lowlands (up to 200m above sea level) and make up for 81.8% of the city's entire area.Regions under 100m above sea level are hilly and are comprised of alluvial deposits. Here Morak Mountain(帽洛山, 385m) and Obong Mountain (五鳳山, 205m) are situated and provide a pleasant natural environment amid an urban backdrop.
