La Pierre à la Bague is a shallow Planier reef plateau with pinnacles and cuts, plus small wreck remnants scattered across the bottom. Gorgonians, colorful sponges, moray eels, and schools of pelagic fish make it feel busy even when the water is calm. It is usually dived by boat from Marseille, and the site is best when wind and surface chop stay mild.
