Oryukdo, a hidden attraction in Busan(Korea)

The islands that make up Oryukdo are Shield Island, Sol Island, Suri Island, Songgot Island, Gulseom Island, and Lighthouse Island in order of proximity to the mainland. It is called Oryukdo because these islands become 5 islands at low tide and 6 islands at high tide. Oryukdo Lighthouse is located on the lighthouse island that is farthest from the mainland. It is the only Oryukdo island where people can enter. Oryukdo Lighthouse is located in a place where ships entering Busan Port must pass, so it serves as a gateway to Busan.
