Current-swept volcanic reef off the Mosteiros islets.
Use a local boat operator to time the current window and pickup.
On the western face of the Ilhéus dos Mosteiros, this volcanic shoal suits experienced scuba divers who want a deeper Atlantic profile, strong current, black coral, and passing larger fish. Plan the dive as a boat operation with steady weather, conservative gas, and a clear exit plan.
Site Conditions

Use conservative gas planning, confirm pickup timing before entry, and treat the current as a core part of the dive plan.
Access Restrictions

Community notes to help plan your visit.
Scuba Diving
Best for experienced scuba divers comfortable with current and a deeper rock-wall profile.
Freediving
Not a primary freedive site; the depth and current make it a poor choice for casual apnea sessions.
Snorkeling
Not a practical snorkel target compared with sheltered Mosteiros waters nearby; the outer face is too exposed for casual surface time.
