Les Fillettes is a boat-accessible dive site located off the Crozon Peninsula in France. The site features a depth range of 10 to 30 metres and is subject to moderate currents. Divers can expect visibility between 5 and 10 metres. Water temperatures remain cool throughout the year, ranging from 11C to 13C. Species recorded around this area include various wrasses, sea squirts, shannies, and clingfish, alongside occasional sightings of European common cuttlefish and grey seals. Due to the depth and current conditions, this site is best suited for divers with appropriate experience in temperate marine environments.

Mingant, located off the Crozon Peninsula, offers a diverse underwater experience combining reef, wall, and wreck diving. Divers can explore depths between 10 and 25 metres, with visibility typically ranging from 5 to 10 metres. The site is characterised by strong currents, which necessitate careful planning around slack water to ensure a manageable dive. Due to the cold water temperatures of 11 to 13 degrees Celsius, a drysuit is recommended. The presence of wrecks and potential overhead environments requires appropriate training and navigation skills. Access is strictly by boat, and divers should monitor local conditions for surge and current strength before departure.

Tombant du Belge is a challenging wall dive located off the Crozon Peninsula, featuring a steep drop-off that descends from 25 to 51 metres. Due to the offshore location and strong currents, this site is strictly for intermediate to advanced divers and requires boat access. Divers should anticipate visibility between 5 and 10 metres, necessitating close-up inspection of the wall structure. Water temperatures remain cool, ranging from 10 to 12 degrees Celsius throughout the year, making a drysuit or thick wetsuit essential. Given the significant depths, divers must maintain strict awareness of nitrogen narcosis and time their entry to coincide with slack water to manage the powerful currents.

The Swansea Vale is a wreck site located 4000 metres off the Crozon Peninsula, resting at depths between 28 and 31 metres. This intermediate-level dive requires boat access and is characterised by strong currents, making it essential to time descents around slack water. Visibility typically ranges from 5 to 10 metres. Divers should maintain strict buoyancy control and remain aware of potential entanglement hazards within the wreck structure. Due to the significant depth and current conditions, careful dive planning is necessary for this 41-minute average dive. Water temperatures remain cool throughout the year, ranging from 11C to 13C.

Pointe de Penhir is located on the western tip of the Crozon Peninsula, France, featuring a combination of natural and artificial reef structures. Divers can explore depths ranging from 15 to 24 metres, with an average depth of 15 metres. Visibility at the site varies between 10 and 30 metres. Due to the presence of strong currents, rip currents, and hazardous surf at the shore, boat access is required for all dives. Conditions can change rapidly with the tide, making it essential to plan dives around slack water. Full exposure protection is necessary year-round as water temperatures remain between 11 and 13 degrees Celsius.

La Cormorandiere, located off the Crozon Peninsula, is a reef and kelp forest site reaching depths of 15 to 20 metres. This site is defined by strong currents, which can include down currents that affect buoyancy. Divers must remain aware of entanglement risks when navigating through the thick kelp. Visibility typically ranges from 5 to 10 metres, and water temperatures remain between 11 and 14 degrees Celsius. Access is by boat only, and the site is suitable for intermediate divers. Night diving is permitted for those seeking a different perspective of the reef. Divers should plan their visit around slack water to manage the challenging current conditions effectively.

Le Dellec is a wreck and artificial reef site located off the Crozon Peninsula. Suitable for beginners, the site ranges from 5 to 16 metres in depth with an average of 12 metres. Divers can access the site from the shore or by boat. Conditions include mild currents and visibility between 5 and 10 metres. Marine life observed here includes crabs, sea stars, brittle stars, and occasionally European common cuttlefish, orange-clubbed nudibranchs, and squat lobsters. Due to the wreck structure, divers must remain aware of entanglement risks and overhead environment hazards. Boat traffic is a potential hazard at the surface, and a drysuit or 7mm wetsuit is recommended for the 11 to 14 degree Celsius water.

Marco Polo III is a reef site located off the Crozon Peninsula, accessible only by boat. The site sits at a depth of 27 to 30 metres, requiring divers to hold an appropriate certification for these depths. Conditions include a moderate current and visibility typically ranging between 5 and 10 metres. Water temperatures are cool, fluctuating between 11 and 13 degrees Celsius throughout the year, making a drysuit or thick wetsuit necessary for thermal protection. Divers should plan their profiles to work with the current and monitor air consumption closely due to the cold water environment.
