Boat-accessed cave dive on Ile Plane with a short overhead passage.
Boat-accessed cave dive on Ile Plane with a short overhead passage.
Boat access, moorings, and Calanques logistics are easiest with a local operator.
La grotte à Perez is a classic Calanques cave dive on Ile Plane, with a broad cathedral-like opening above a steep wall and a short overhead passage. It is a boat-accessed site for trained divers, known for gorgonians, red coral, langoustes, mostelles, and small Mediterranean fish. The surrounding slope and cave mouth reward patient buoyancy, and the dive works best as a calm, well-briefed boat run with a clear turn point.

Depth range, seasonality, and planning context.
Reported Depth
14m - 40m
Depth Note
Sources place the main cave entrance around twenty to twenty-five meters, with the roof rising into the teens and the surrounding wall dropping to about forty meters.
Best Season
June through October, with cooler shoulder weeks often giving the clearest water.
Typical Conditions
Boat-accessed Calanques cave-and-wall profile, usually manageable for trained divers, with a short overhead section and visibility that shifts with sea state.
Hazards, restrictions, and access requirements.
Key Hazards
Safety Notes
Stay disciplined on buoyancy and gas because this is an overhead cave with a real wall drop-off. Keep penetration conservative and follow the guide's turn point.
Access Restrictions
Boat access only in normal conditions, with Calanques logistics and park rules shaping the day plan.
Legal Notes
Follow Calanques marine-park rules and local boat procedures around the landing stage and moorings.
Community notes to help plan your visit.
Scuba Diving
Best enjoyed as a guided wall-into-cave circuit with careful gas planning and conservative penetration.
Freediving
Only very experienced freedivers should consider the outer wall in calm conditions. The main feature is really a scuba-first cave dive.
Snorkeling
Not a snorkeling site. The interesting part sits too deep and inside an overhead section.
