The day begins at Chalong Pier, where salt-scented wind and the steady thump of a dive boat set the tempo. Instructors meet guests at the lighthouse stairs, run through equipment checks in the warm morning light, then guide small groups out across blue water toward Racha Yai and nearby Racha Noi. Below the surface, coral bommies and gentle slopes reveal parrotfish, moray eels and gardens of hard and soft coral; above, the islands sit as rounded volcanic ridges carved by time.
