About this dive site
Granite boulders and Andaman reefs in a classic Thai park.
Similan Islands National Park pairs elephant-head boulders at sites like Elephant Head Rock with coral ridges at East of Eden and Anita’s Reef. Mantas and whale sharks are occasional visitors in season. Park closures apply each monsoon, confirm opening dates and liveaboard schedules before booking.
Most trips target November - April, but wind, swell and current still decide the day's site. Calendar peak is November - April, but skippers still move sites when wind, swell or current change. Book with a crew that knows Similan Islands day to day, not just the map pin.
