Other people's footage, not advice: how someone else dives here says nothing about what suits your team. Dive within your training.
The dive
A short, roomy cave. Red coral grows on the ceiling; on the wall you see spiny lobster, moray eels and gorgonians with basket stars. Visibility is up to 25 m in season.
Profile and sections
A short, roomy cave. Red coral grows on the ceiling; on the wall you see spiny lobster, moray eels and gorgonians with basket stars. Visibility is up to 25 m in season. The dive is often combined with the wall or the arches of Plane (-15 m).
The cave is named after the marine biologist J.-M. Pérès, who ran experiments here in the mid-20th century (sponge farming); the landing was built for him.
- Depth and profile
- Entrance at -20 to -25 m, ~10 m wide · cave ~20 m long · narrow chimney rising to ~-7 m · wall below to -40/-43 m (sand)
- Configuration
- All configurations. Do not go through the narrow chimney.
- DPV: Not DPV-suitable (estimate)
- Short cave (~20 m); a scooter adds nothing.
Who can dive where
- At least Open water / no overhead
- Configurations: Backmount / twinset / Sidemount / CCR / Small cylinders / no-mount (speleo sumps)
- Goes down to 25 m (trimix or deco may be needed)
This is how the planner decides who in your team may dive this cave. Rules your own trip adds (organizer, a mail, the AI) show with your trip.
How to get there
By boat only, with a Marseille dive centre (e.g. from Port de la Pointe Rouge) or your own boat. The cave is at the east end of Île Plane, below the concrete landing: ~1 minute swim from the landing to the entrance. Moor on the park's white diver buoys; do not anchor on seagrass or coralligenous reef. The 'triangle Cousteau' archaeological zone (no diving, no anchoring) lies near Riou and Plane: ask your centre where its boundary is.
