Mu Koh Angthong National Marine Park is a limestone-island park with shallow reefs, sheltered bays and broad marine-life variety. It works as a boat-based snorkel and scuba area rather than a single wreck or wall, with the best days coming when calm weather, cleaner water and manageable current line up.
