The waters surrounding Cap d'Antibes are a protected Natura 2000 marine area, making them some of the richest and clearest on the French Riviera for underwater exploration. Snorkeling is accessible to everyone directly from several beaches and rocky coves, while scuba diving operations offer guided dives around the Cap.
The standout snorkeling spot is the Baie des Milliardaires underwater trail at the foot of Villa Eilenroc, where shallow water reaching only 4 meters is teeming with life. Posidonia seagrass meadows shelter sea bream, wrasse, lobsters, and yellow gorgonian corals.
Diving operators run courses for all levels, from complete beginners to instructor certification. The best visibility is typically from May to October, with water temperatures ranging from 18 to 25 degrees Celsius.
