Geumneung Beach

This guide to Geumneung Beach in Jeju starts with an optical illusion: the small island of Biyangdo just offshore looks close enough to wade to, though nobody quite makes it. It traces the local legend that the island broke off Mount Halla's summit and flew here, and follows the Goryeo-dynasty court records that describe fire breaking from its slopes for several days. Stand at low tide, when the sand flats reach furthest out and the water goes glassy calm.
