Oryukdo
Group of islands in Busan, South Korea
Oryukdo (Korean: 오륙도; lit. Five–Six Island) is group of islands located in Yongho-dong, Nam-gu, Busan, South Korea. The name reflects the fact that the island group can consist of either five or six islands, depending on the current tides.
The islands are uninhabited except for Deungdaedo, which has a lighthouse. The other islands are Usakdo, Surido, Gonggotdo, and Guldo. Depending on water level, Usakdo can also be separated into two islands, which are then named Bangpaedo and Sol.[3]
