Plage des Aigues Douces, Port-de-Bouc

What Seaglassmap found here

A run of small urban beaches on the Golfe de Fos, facing the seventeenth-century Fort de Bouc across the channel mouth. A collector who worked these beaches in early 2025 reported more glass than they could carry, some of it still embedded in the beach. Industrial harbour history keeps the supply coming. French rules favour you here: taking sea glass off the beach is allowed, taking pebbles is not.
