Open Water

Not a snorkel site - no - depth range (down to ~30m) and swim-through cavern features make this a scuba dive site, not documented as a snorkel option

Safety notes

Overhead-environment elements in narrow chimneys/swim-throughs (though generally open/well-lit, not true cave diving); current convergence zones outside the cavern network at the island's southern tip; approx. 90-minute bottom time dives require good air management
