About this site
Les Moulieres off Ile de Groix offers vibrant underwater landscapes with rocky outcrops and sandy patches. Strong currents attract pelagic species like barracuda and bass, while the seabed teems with lobsters, crabs, and colorful anemones. Visibility varies but often reaches 15 meters. The site suits experienced divers due to shifting tides. Kelp forests and granite formations create a dynamic dive with surprises around every corner. Water temperatures range from 12°C in winter to 18°C in summer. A wetsuit or drysuit is essential. The area is known for its rich biodiversity and dramatic underwater terrain shaped by Atlantic swells.
