Port of Le Croisic, Fishing and marina port in Loire-Atlantique, France

The Port of Le Croisic is a fishing and marina port in Le Croisic, Loire-Atlantique, not Brittany. Its marina lies mainly in the Chambre des Vases, also called the Hervé-Rielle basin, a series of small basins sheltered by jonchères, islets built up over centuries from ballast dumped by ships loading salt from the Guérande marshes. In 2016 it offered 363 berths, 27 of them for visitors.

The port lies in Le Croisic, in the Loire-Atlantique department, not in Brittany. Its basins, called "chambres", were gradually formed over the centuries by ballast dumped by ships that came to load salt from the Guérande marshes. The marina is mainly in the chambre des vases, also named bassin Hervé-Rielle, reached through the Pertuis du Roi.

The port's name for its central basin, the chambre des vases, recalls the ballast and silt that built it. The auction house, rebuilt in 1982, sells fish, crustaceans, molluscs and shellfish seven days a week between fishermen and wholesalers. Local conchyliculture supplies cockles, clams and Pacific oysters, alongside scallops.

The harbor is accessible through the Pertuis du Roi entrance with clear markings to guide you through the basin areas. Tidal movements affect water depths, so checking conditions before arrival helps ensure safe navigation.

The basins are separated by "jonchères", small islands built up over centuries from ballast dumped by ships that came to load salt from the Guérande marshes. The marina lies mainly in the chambre des vases, also called bassin Hervé-Rielle, and had 363 berths in 2016, 27 of them kept for visitors.
