Ijakdo Island is made up of Daeijakdo Island and Soijakdo Island. In the past, the island was called Ijeokdo Island because it served as a hideout for pirates. The sea, mountain, and shoal exist in harmony.

The beauty of Daeijakdo Island comes from the view of the blue ocean from the peak of Buasan Mountain and the shoal that only appears during low tide. The shoal almost reaches Soijakdo Island and creates a large field of sand. The shoal is also called pulchi and only appears during low tide for six hours a day.
