Marine reserve of Cerbère-Banyuls, Marine nature reserve in Banyuls-sur-Mer and Cerbère, France.

The Marine reserve of Cerbère-Banyuls is a protected nature area extending across the Mediterranean coast between two towns, reaching two kilometers into the sea. It contains diverse marine habitats ranging from shallow rocky areas to deeper underwater zones.

The reserve was established in 1974 as France's first marine protected area, created in response to fishing pressure and pollution threatening the coastal waters. Its creation marked an early milestone in protecting Mediterranean marine life through legal designation.

The reserve's underwater trail off Peyrefite beach, about 250 m long, is marked by buoys and submerged information panels; a sound-tube system plays audio commentary for swimmers with mask and snorkel. A lifeguard supervises it during opening hours, and motorboats are kept out of the marked zone.

Swimming is allowed throughout the reserve, but spearfishing and underwater hunting are banned everywhere. Scuba diving is permitted except inside the integral protection zone, where it is prohibited. The 250-metre underwater trail runs from Peyrefite beach, marked by buoys and submerged information panels, with a lifeguard on duty during opening hours.

The reserve's underwater trail off Peyrefite beach runs about 250 metres through a marked, boat-free zone watched by a lifeguard during opening hours. Swimmers with mask and snorkel follow submerged information panels and buoys, and a sound system pipes commentary through an underwater snorkel tube.
