Île Ronde

Île Ronde is a coastal dive site off Brittany, France, near Plougastel-Daoulas. The site sits in shallow to mid-water, with typical conditions for the region. Entry is via gentle shore-to-eel shelf access or small boat drop-offs from nearby harbours. Expect seabed topography with rocky outcrops and short wall sections, suitable for skill-building dives and drift entries in calm seas. Common Western European marine life includes wrasses, gobies, blennies, and common polychaetes, with posidonia seagrass meadows nearby in the bay. Visibility can vary with tides and weather, generally best in stable conditions. Divers appreciate proximity to the coast and easy access from nearby towns like Plougastel-Daoulas, Lanvéoc and Roscanvel, making Île Ronde a convenient local option for a half to full day of diving from the point d’ancrage. For local centers, several Brittany-based operators run trips from the nearby ports, offering guided dives and equipment rental.
