Community notes to help plan your visit.
Scuba Diving
Best for divers comfortable on wall terrain and occasional current swings; the reef top and light shafts are the signature features.
Freediving
Only suitable for experienced freedivers in calm conditions; the wall and current make it a poor casual fit.
Snorkeling
Not a casual snorkel target because the wall and current sit beyond a relaxed surface excursion.
