Community notes to help plan your visit.
Scuba Diving
Scuba is the primary fit here; the site is designed around boat drops, reef structure, and a multi-level wall profile.
Freediving
Freediving is not the primary use case because the site is a deeper boat reef with wall sections.
Snorkeling
Not a primary snorkel site; it is better suited to scuba than casual surface snorkeling.
