Lonely Island Ruins (めだま島遺跡, Eyeball Island Ruins) is a dungeon location in Golden Sun: Dark Dawn. It is one of several locations that holds a piece of the Umbra Gear. The Lonely Island Ruins are located west of Tonfon, next to the Endless Wall. Following the path just below the wall to its end allows the player to reach the area where the ruins are located. Like the other Umbra Gear dungeons, access to the Lonely Island Ruins requires the the use of the Search Psynergy, which reveals a bridge to the small island where the cave is located.
