Songaksan Mountain is also called 99 Bong (99 Peaks) due to its 99 small peaks. The main peak rises 104 meters above sea level. To the northwest of the main peak is an expansive prairie with several peaks. There is a crater about 500 meters in diameter and 80 meters in depth, with some blackish volcanic ash still remaining inside. Looking along the jagged coastline, one can spot the large man-made caves built during the Japanese occupation. The seashore at the base of Songaksan Mountain is a famous fishing ground and diverse fish such as sawedged perch and black porgy are caught here.
