Before you arrive
Access notes
Managed shore access through a current local dive center; obtain a same-day site and exit briefing. Reconfirm certification, recent experience, medical fitness, gas plan, emergency oxygen, communications, evacuation and recompression arrangements. Rounded display point only—not an entry, launch, mooring, wreck position, cave entrance, descent line or navigation waypoint.
Plan within your training
Conditions and hazards
Atlantic swell, surge, changing visibility, surface traffic, sharp volcanic rock and possible current.

Facilities and support
Current Madeira operators provide guided access and commonly offer rental equipment, air or nitrox fills and surface support; exact oxygen, accessibility, boat and emergency capabilities must be reconfirmed for the chosen operator.
Independent resource notice
This record is a starting point for independent verification. Access, closures, moorings, weather, currents, depth, visibility, operator availability, and site conditions can change without notice. Confirm current information with the responsible operator, property owner, managing authority, or another qualified local source before planning or attempting a dive.
