Key Hazards
Safety Notes
Keep strong buoyancy control, stay inside your limits, and do not force the site when the current or boat handling is off.
Access Restrictions
Treat it as a guided protected-area dive and respect the outer-sea current and boat-timing constraints.
Legal Notes
Follow park rules and marine-park operating norms for Fernando de Noronha's outer-sea sector.
Community notes to help plan your visit.
Scuba Diving
A canyon-style boat dive for divers who want structure, movement, and a richer marine life mix than a flat reef.
Freediving
Not a freedive-first target; the current and canyon profile make it much more of a scuba site.
Snorkeling
Not a snorkel site; the main route sits below the surface and needs a proper dive plan.
