Cap Ferret offers a compact but varied underwater scene shaped by exposed coastal conditions and the influence of Arcachon Bay. Dive sites range from a wreck and artificial reef to deep reef structures, best reached by boat. Snorkellers find shallower ground within the bay's calmer waters. Common Octopus, European Common Cuttlefish, and Jewel Anemone are regularly observed, while the occasional Gray Seal or Marbled Electric Ray adds real surprise to any dive.

Water stays cool through winter and early spring, warming gradually from late spring into summer and peaking in August and September. The warmest months draw the most divers and offer the most comfortable conditions. Exposed sites like Le Frigolin carry depth and current considerations that reward careful planning.

Jewel Anemone, Giant Green Anemone, and Brittle Star are common on the reef structures, while European Conger and Small Red Scorpionfish appear regularly.

The top dive sites at Cap Ferret, including Le Chariot and Le Frigolin, are rated intermediate and reach considerable depths. Boat access is required for both. Beginners would be better suited to the shallower snorkelling sites, and those looking to dive should have solid buoyancy skills and relevant experience before attempting the deeper reef and wreck sites.
The main dive sites require boat access and are reached offshore from the peninsula. Several local operators, including Océana Ecole de Plongée and Dive In The World, run guided boat trips to these sites. Snorkelling spots within Arcachon Bay are more accessible and may allow shore entry at calmer locations.
Diving takes you to offshore wrecks and deep reef structures where cephalopods, conger, and rays are the draw. Snorkelling is centred on shallower bay waters, where starfish, blennies, and anemones are the main attraction. The two activities cater to quite different skill levels and conditions, making Cap Ferret suitable for mixed-ability groups.
