Overview
Famed limestone sea cavern used as a James Bond filming location, with a domed ceiling pierced by skylights that beam shafts of light through clouds of sergeant majors. Mostly a snorkel site, but a shallow scuba option is offered at slack tide.
Briefing note
Enter at slack tide — currents through the swim-throughs can rip on flood and ebb.

Sources & methodology
How we summarise this
We aggregate confirmed occurrence records from GBIF and OBIS within a fixed radius of each dive site. Occurrence records confirm presence and reveal seasonality clustering, but they DO NOT measure per-dive probability — there is no eligible-effort denominator. We deliberately do not publish a numeric '% chance of sighting' from this data.
