Dive-site story
Located off the coast of Lorient in southern Brittany, the waters surrounding Île de Groix feature mineral-rich geological formations, extensive kelp forests, and historic Atlantic shipwrecks. Diver routes range from shallow granite boulder slopes along sheltered coves to exposed offshore plateaus and deep drop-offs. Rocky channels and submerged overhangs harbor thriving cold-temperate ecosystems, with Atlantic swells and tidal flows dictating daily dive plans.
Diverse underwater geology marked by mica-schist ridges, granite boulders, and natural swim-throughs
