Épave Afrique is a deep wreck dive located 50 kilometres off the coast of Arcachon Bay, France. Resting at depths between 40 and 46 metres, this site is reserved for advanced divers. The environment features moderate currents and visibility ranging from 15 to 25 metres. Divers must manage cold water temperatures of 10 to 15 degrees Celsius and the risks associated with an overhead wreck environment, including entanglement. The structure provides a habitat for various reef fish and invertebrates. Due to the depth and distance from shore, boat access is required, and bottom times are typically limited to 25 minutes to account for decompression requirements.

Ponton Bigue is a wreck and artificial reef located in Arcachon Bay, France. Resting at depths between 20 and 34 metres, this site is suited for intermediate divers. The environment is characterised by moderate currents and visibility ranging from 5 to 10 metres. Water temperatures are cold, fluctuating between 10 and 16 degrees Celsius throughout the year. Divers should utilise appropriate thermal protection, such as a drysuit or a 7mm wetsuit with hood and gloves. The structure supports a variety of local reef fish and invertebrates. Due to the depth and current, precise buoyancy control and careful dive planning are essential for all visitors.

The John G McCullough is a wreck site located off the Atlantic Coast of France, resting at depths between 46 and 50 metres. This site requires boat access and is suited for intermediate divers due to the significant depth. Visibility varies from 5 to 20 metres, and currents are generally mild. Divers should be prepared for water temperatures ranging from 10 to 16 degrees Celsius, necessitating appropriate thermal protection. The wreck structure presents potential entanglement hazards and sharp surfaces, requiring careful navigation. The surrounding habitat supports various reef fish and invertebrates typical of the region.

L'Afrique is a wreck dive located 50 kilometres off the coast of Arcachon Bay, France. Resting at depths between 40 and 45 metres, this site is suited for intermediate divers capable of managing deep, cold-water conditions. The wreck offers structural complexity and penetration opportunities, requiring careful attention to entanglement risks and overhead environments. Visibility typically ranges from 10 to 30 metres, with mild currents that can shift unexpectedly. Water temperatures remain between 10 and 15C, necessitating appropriate thermal protection. Divers should plan for limited bottom times due to the significant depth. The site supports a variety of marine life typical of the Atlantic region, including reef fish and invertebrates.

The Sequana is a wreck and artificial reef located off the Atlantic Coast of France in Arcachon Bay. The site sits at depths ranging from 25 to 47 metres, requiring boat access and intermediate to advanced diving skills. Visibility typically ranges between 5 and 10 metres, and divers should expect mild currents. Due to the significant depth, careful management of decompression obligations and nitrogen narcosis is essential. The wreck structure presents entanglement risks, so penetration requires thorough planning. Divers should use a surface marker buoy and a dive computer with decompression capability. Guided tours are available from local operators based on Île d'Yeu.

The Californian is a wreck and artificial reef located in Arcachon Bay. The site features a varied topography with depths ranging from 5 to 30 metres. Divers should expect mild currents, though surge and swell can affect conditions, particularly in the shallower sections of the structure. Visibility typically fluctuates between 5 and 15 metres. Due to water temperatures ranging from 11 to 17C, a well-insulated wetsuit or drysuit is necessary. This site is accessible only by boat and is suited for intermediate divers. The structure supports a variety of marine life typical of the Atlantic coast habitat, including reef fish and invertebrates.

Épave Bacchi is a shore-entry dive site located in Arcachon Bay, France. This site is accessible year-round without the need for a boat. It is suitable for beginners due to the shallow water and lack of specific hazards. Divers should note that both visibility and current are variable, so checking local conditions before entering the water is recommended. Water temperatures fluctuate between 10C and 20C throughout the year, requiring appropriate thermal protection. As there are no confirmed facilities on site, divers must arrive self-sufficient with all necessary equipment and hydration.

Ours des Vieilles is a shallow reef located 600 metres offshore in Arcachon Bay. This site is well-suited to beginner divers, offering a relaxed environment with mild currents and depths ranging from 4 to 16 metres, with an average of 10 metres. Visibility typically spans 7 to 10 metres, allowing for clear observation of the reef topography. The site is accessible year-round by boat and permits night diving. Due to water temperatures ranging from 10 to 18 degrees Celsius, a thick wetsuit of at least 7mm or a drysuit is recommended for dives outside of the summer months.
