L'île d'Ouessant in the Molène Archipelago features diverse underwater topography, including kelp forests, reef walls, caves, and various wrecks. Depths range from 5 to 60 metres, with visibility typically between 10 and 20 metres. Due to strong currents and significant boat traffic, this site is suited for intermediate divers. Boat access is required, and tidal windows are short, necessitating precise planning around slack water. Water temperatures remain between 10 and 13 degrees Celsius throughout the year, with upwelling occurring in the area. A drysuit and hood are strongly advisable to manage heat loss during dives.

Keradog is a reef and kelp forest site located in the Molène Archipelago. The site is defined by its extensive kelp growth across the reef structure. Divers should expect water temperatures between 11C and 17C, necessitating a well-fitted wetsuit. Visibility typically ranges from 5 to 10 metres. Access is strictly by boat to avoid the surf and shore break present at the entry point. While currents are generally mild, they can develop into strong flows, making it essential to time dives around slack water. This site is suitable for intermediate divers who are comfortable managing tidal conditions and boat entries.

The Peter Sif is a technical wreck dive located in the Molène Archipelago, France. Resting at a depth of 57 metres, this site is strictly for advanced divers with deep diving qualifications. Access is by boat only, and divers must account for moderate currents and potential surges. Visibility at the site ranges from 10 to 30 metres. Water temperatures remain consistently between 10 and 12 degrees Celsius throughout the year, making a drysuit and full thermal protection essential. Due to the depth and current conditions, precise planning of the slack water window is required to ensure a safe dive.

The Okawongo is a wreck located in the Molène Archipelago, offering a significant depth range from 5 to 60 metres. This offshore site is situated 1000 metres from the shore and requires boat access. Divers encounter strong currents throughout the dive, making it suitable only for advanced divers. Visibility at the site typically ranges between 10 and 30 metres. Water temperatures remain cold, consistently between 10 and 13 degrees Celsius, necessitating the use of a drysuit and hood. Meticulous planning around tidal tables is essential to access the wreck during the narrow slack water window.

Le Louis David is a wreck dive located in the Molène Archipelago, France. The site features a wreck resting in depths reaching 45 metres. Access is by boat only, and the site is suited for intermediate divers due to strong currents. Visibility is typically between 5 and 10 metres, requiring divers to maintain close group contact. Water temperatures remain between 10 and 12 degrees Celsius, necessitating a drysuit or thick wetsuit. Divers must time their descent and ascent around slack water to manage the current. An SMB and a cutting tool are recommended due to the current and sharp edges on the structure.

The Molène Archipelago features extensive kelp forests and reef structures within a protected marine park. Snorkellers access this site by boat, located 15 kilometres from the shore. The environment is characterised by strong currents, surge, and surf, requiring intermediate skill levels for safe navigation. Water temperatures range from 11C to 16C throughout the year. Species recorded around this area include grey seals, common octopus, spiny spider crabs, and various wrasses. Due to the presence of boat traffic and challenging water conditions, guided tours are recommended for those visiting this remote archipelago.

L Eildon is a challenging marine site located 1500 metres off the coast of the Molène Archipelago. The topography consists of a mix of reef structures, kelp forests, and a wreck, spanning depths between 5 and 30 metres with an average of 18 metres. Access is strictly by boat. Divers must navigate strong currents and unpredictable surge, with visibility typically ranging from 5 to 15 metres. Water temperatures remain cold, between 11 and 13 degrees Celsius, due to deep water upwellings. Given the strong tidal currents and entanglement risks within the kelp, this site is suitable for intermediate divers with solid buoyancy control and current-diving experience.

Le Colombian is a challenging wreck dive in the Molène Archipelago, France, with depths reaching 60 metres. The site is strictly for advanced divers due to the significant depth, strong currents, and potential for nitrogen narcosis. Visibility typically ranges between 5 and 10 metres. Access is by boat only, and divers must coordinate with a charter skipper to time their descent for slack water. The wreck structure is subject to strong currents, requiring careful planning and navigation. Divers should remain vigilant regarding passing boat traffic during ascents and safety stops. Facilities available include air fills, changing rooms, and showers.
