Gujan-Mestras is officially recognized as the capital of oyster farming on the Arcachon Basin.
The harbor layout is dictated by the extreme tidal range of the basin, which causes the water to recede significantly at low tide.
The traditional shacks at the port are often color-coded, a long-standing local practice among families of oyster farmers.
The pinasse, the iconic local boat, was traditionally built from pine harvested in the nearby Landes forest.
The Maison de l'Huître at the port utilizes interactive exhibits to explain the 18-month life cycle of an Arcachon oyster.
Port Larros is one of seven historic oyster-farming harbors located along the coast of Gujan-Mestras on the Bassin d'Arcachon. The site serves as a functional working port where traditional flat-bottomed oyster boats, known as pinasses, are moored alongside active oyster shacks. It hosts the Maison de l'Huître, a museum dedicated to the history and techniques of local oyster cultivation. The area features a waterfront promenade that connects the harbor to the surrounding marshlands and mudflats. It is a center for regional maritime heritage, emphasizing the symbiotic relationship between the town and the tide-dependent oyster industry. Visitors can observe the daily activity of ostreiculteurs processing their harvest directly from the boats to the docks.

Check the tide tables before visiting, as the port looks vastly different at high tide versus low tide.
Bring comfortable walking shoes to navigate the wooden boardwalks and sandy harbor paths.
Sample oysters directly from the producers' huts at the port for the freshest experience.
Do not attempt to walk out onto the mudflats during a rising tide as the water fills the channels rapidly.
Avoid walking onto private oyster-working docks or handling equipment without permission from the farmers.
