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.

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.

The Angelo Patagonian is a wreck dive located 25 kilometres off the Atlantic coast near Les Sables-d'Olonne. Resting at a depth of 45 metres, this site is reserved for advanced divers. The wreck features an overhead environment with structures and swim-throughs, requiring precise buoyancy control and careful navigation. Visibility typically ranges from 10 to 30 metres, while water temperatures remain cool, between 10 and 16 degrees Celsius. A boat is required to reach the site, and divers should plan for mild currents. The surrounding habitat supports various temperate marine life, including reef fish and invertebrates common to the region.

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.

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.

The Yusenquashia Maru is a shipwreck located in Arcachon Bay, resting at depths between 6 and 15 metres with an average depth of 10 metres. This site is accessible only by boat and is suited for intermediate divers. Conditions include a mild current and visibility of approximately 5 metres. Divers should be prepared for surge and swell, which can make entry and exit technical. Due to active boat traffic in the area, it is essential to deploy a delayed surface marker buoy upon ascent. Air fills and boat charters are available locally to support dives, which typically last around 45 minutes.

Anse des Soux in Arcachon Bay offers a varied underwater landscape featuring natural stone arches and small grottos. This site is suitable for beginners, with depths ranging from the surface down to 12 metres. Access is via the shore, where snorkelers should be aware of potential surf and rip currents. Water temperatures are notably colder than on the mainland, fluctuating between 10C and 20C throughout the year. Species recorded around this area include wrasses, conger eels, striped red mullet, sea stars, tompot blennies, cod, snails, sea squirts, triplefins, and sea cucumbers.

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.
