Grotta del Tinetto is a boat-access grotto with a dramatic cave.
Grotta del Tinetto is a boat-access grotto in the Porto Venere Marine Protected Area, with a wide entrance on the western side of Tinetto and a dramatic cave interior that rewards slow, controlled diving. The walls and ceiling carry dense marine life, so the site suits divers who want a scenic, torch-lit passage rather than a fast open-water swim.

Depth range, seasonality, and planning context.
Reported Depth
5m - 18m
Depth Note
The dive starts around a 5 m wall step and reaches the cave around 18 m.
Best Season
Spring through early autumn, with low season preferred for quieter boat traffic.
Typical Conditions
Boat-access grotto diving with a wide entrance, vertical wall sections, and marine life packed into the cave surfaces. Currents and visibility can change, so keep the dive slow.
Site conditions, restrictions, and access requirements.
Site Conditions
Safety Notes
Stay in line, control buoyancy, and carry a torch; the cave can silt up quickly if fins or hands stir the bottom.
Access Restrictions
Treat it as a guided marine-park dive and avoid forcing it in poor sea state or busy summer boat traffic.
Legal Notes
Follow Porto Venere marine-park rules and any operator briefing.
Community notes to help plan your visit.
Scuba Diving
Scuba is the intended mode here; use a torch, stay streamlined, and move one diver at a time through the grotto.
Freediving
Not a freedive site; the cave structure and buoyancy demands make scuba the clear choice.
Snorkeling
Not a snorkel site; the main features are submerged inside the grotto.
