Crossbone Isle Dungeon cheats for Golden Sun: Dark Dawn

Crossbone Isle Dungeon

To get access to the final optional dungeon you must defeat the final boss and save your game after the credits. Reload the cleared saved game file and sail south from Tonfon until you reach a 'C' shaped peninsula at the edge of the world. Enter the whirlpool at that location and sail east from the exit until you find an island with a cave. This cave will lead to the entrance of Crossbone Isle which is the hardest boss of the game.
