You scramble and swim through the whole system to Devil's Bay. Nothing else in the Caribbean looks like it, this is granite in a limestone sea. The boulders are eroded remnants of a volcanic granite batholith that cooled underground 40+ million years ago, then weathered out. Sailors historically watered here, hence 'the Baths'.
