Most of North Korea is a series of medium-sized mountain ranges and large hills, separated by deep, narrow valleys. The highest peak, Paektu-san on the volcanic Baekdu Mountain, is located on its northern border with China, and rises 9,002 ft. (2,744 m).
Along the west coast there are wide coastal plains, while along the Sea of Japan (East Sea) coastline (North Korea's lowest point at 0 m), narrow plains rise into mountains. Similar to South Korea, dozens of small islands dot the western coastline.
North Korea's longest river is the Yulu (Yalu). Other large rivers include the Tumen, Taedang and Imjin.
