Dive-site story
Situated in the western Gulf of Thailand, Koh Tao is defined by granitic underwater boulder formations, coral nurseries in protected coves, and outlying submerged seamounts. While inner bays provide calm water for training, outer pinnacles pull in pelagic visitors when currents run.
Submerged granite pinnacles draped in sea anemones
Sheltered fringing reefs populated by juvenile reef fish and sea turtles
Occasional offshore whale shark encounters around isolated pinnacles
