Yongdae Gap is a headland in the middle of North Korea's eastern coast, forming the southeastern corner of South Hamgyong's Tanchon and the western point of a narrow bay sheltering Songjin and Hwadae. The area is known for its rugged terrain, with Wonsandok San rising to an elevation of 504 meters (1,654 feet) about 4 miles due north of the cape. The highest visible mountain from the point is Yongyon San, which rises to an elevation of 1598 meters (5,243 feet) about 17 miles north-northwest.

The lighthouse is currently closed to the public, and its existence and operation are considered unreliable. The area has a rich history, with Yongdae Gap being known as Cape Schlippenbach or Schlippenback in the 19th century during the Japanese occupation of Korea, and later as Ryūdai-kō.
