Berlenga reefs and grottos dive guide.

Depth

8-28 m

Level

Intermediate

Access

Boat diving from Peniche to Berlenga Grande reefs, granite boulders, walls and grotto entrances inside a protected archipelago.

Best season

Highly seasonal and weather-dependent; summer has the most boat access, but Atlantic swell can cancel at short notice.

Safety

Remote-site logistics, cold water, surge and boat pickup require conservative planning and operator briefings.

Hours

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