Petit Port

Petit Port is Arcachon's bustling marina and one of France's third-largest, so you're in serious company here — both recreational and working boats share the water, giving it an authentically salty character rather than a purely polished resort feel. It's home to a genuine artisanal fishing fleet, with trawlers and gillnetters heading out regularly, which means the docks have real life to them at all hours. The marina sits right on the Arcachon Basin, putting you within easy reach of the Dune du Pilat, the oyster villages of the Cap Ferret peninsula, and the town's Belle Époque seafront.
