Dive-site story
Hin Raab sits south of Koh Chang as an offshore granite pinnacle structure surrounded by extensive coral gardens and sand patches. Massive boulder stacks create sheltered swim-throughs, crevices, and small overhangs before sloping gently onto the seabed. Coral cover features hard tabular and staghorn formations mixed with extensive carpets of sea anemones. It serves as one of the staple dive sites in the Mu Koh Chang National Park, suitable for training dives while offering enough structural variety for experienced divers.
Granite boulder formations with swim-throughs and overhangs
Dense fields of sea anemones inhabited by skunk clownfish
Frequent encounters with resting blue-spotted ribbontail rays on sandy perimeters
Occasional transient whale shark sightings along the outer drop
