Depth

4-18 m

Level

Open Water with local guide

Access

Boat dive about 2.7 nautical miles east of Sesimbra; remain outside the total-protection zone and use an authorized operator and mooring.

Best season

Diving is possible through much of the year, but the operator chooses the site for wind, swell, visibility and park access; exposed western trips are less reliable in winter.

Safety

Shelter is not guaranteed. Maintain buoyancy around boulders, avoid narrow overhead passages, touch nothing and follow park boundaries and ascent rules.

Hours

No fixed public hours. Boat departures, protected-area access and shore entries depend on operators, permits and sea state.
