About this dive site
A sheltered lagoon, limestone walls and hawksbill turtles off Koh Lanta.
Koh Haa’s small limestone islands offer sandy lagoon areas for carefully supervised training and outer reefs for certified divers. Sloping reef, small walls and crevices support a mix of fish and invertebrates, with hawksbill turtles reported in the area. Nearby chimneys and caverns are separate overhead environments and require suitable training and planning. Confirm seasonal access with your operator, choose an open-water route for your experience and leave turtles room to surface.
Most trips target October - June, but wind, swell and current still decide the day's site. Calendar peak is October - June, but skippers still move sites when wind, swell or current change. Book with a crew that knows Koh Haa day to day, not just the map pin.
