Dive-site story
Situated within the Samae San archipelago south of Pattaya, Koh Chan offers sheltered diving around shallow rocky reefs and sloping sandy beds. Hard coral formations such as massive porites and table corals dominate the shallows, transitioning into patches of soft corals and barrel sponges deeper down. Divers frequently encounter varied reef fish foraging among the rocky outcrops and anemone fields.
Extensive colonies of sea anemones with resident clownfish
Gentle reef slopes suited for relaxed navigation and training dives
Sheltered topography providing calm conditions during prevailing seasonal winds
