Turtle Cavern
Depth is the range from the top of the site to its usual maximum; "recommended cert" is the mainstream-agency level operators usually ask for, not a legal rule. Currents and visibility change daily — treat everything here as planning ranges.
A gaping mouth in the wall near the Drop Off leads into a limestone cavern whose inner chambers hold the skeletons of sea turtles, and some dolphins, that swam in, lost the exit in the dark, and drowned. That fact is the dive's briefing and its warning in one. With lights, a guide who knows the line, and cavern-appropriate training, visitors enter the outer chamber where daylight still ghosts the entrance and bones rest in the silt like museum pieces nobody arranged. Beyond the light zone is cave diving, full stop, with silt that can erase the way out in seconds. The site kills the unprepared; treated properly, it is haunting and unforgettable.
The moment you come for: Skeleton-strewn chambers, cathedral entrance light, a sobering lesson in overhead discipline
Topography: Limestone cavern system opening off the wall near the Drop Off
Current: Still water inside; the wall outside carries normal island current.
Know before you splash
Hazards: A genuine overhead environment with fatal history: total darkness beyond the light zone, disorienting silt, and no direct ascent. Turtles still enter and can panic; give them the exit.
Permits & rules: Permit day required; entry only with a guide, and depth of penetration governed by training.
Conservation: The remains are left untouched as both record and memorial; disturbing them is prohibited.
