Community notes to help plan your visit.
Scuba Diving
An easy but exciting guided boat dive, with an overhead cave section that suits Open Water through advanced divers when run conservatively.
Freediving
Not a freedive-first site. The boat logistics and overhead section make it a scuba-first outing.
