The terrain of Perak is shaped by eruptive masses, giving rise to its hills and mountain ranges. To the east, the Titiwangsa Range marks Perak's border, and its highest point, Mount Korbu, reaching 2,183 meters (7,162 feet), is situated near the Kinta district, near the Kelantan state border. Perak also features other mountain ranges such as the Bintang Mountains and the Kledang Range. Much of the plains are covered by alluvial deposits, with occasional sedimentary rock outcrops.
