About This Dive Site
Twin pinnacles in the open Andaman: Hin Daeng ("Red Rock") breaks the surface, while submerged Hin Muang ("Purple Rock") is Thailand’s tallest vertical wall, blanketed in purple soft corals. Together they form the country’s most reliable site for oceanic manta and whale shark encounters during the late-season plankton bloom.
