Thalasso de Pornic

Thalasso de Pornic in Loire-Atlantique, France, offers iodine-rich Atlantic thalassotherapy on a coastline defined by its medieval castle dramatically perched above the sea—the Château de Pornic, whose feudal towers and ramparts silhouetted against the sky above the colorful fishing port create one of the most picturesque castle-and-harbor compositions on the entire Atlantic coast of France. The iodine-rich seawater used in the treatments reflects the tidal mineral richness of the Loire estuary mouth, where the freshwater of France's longest river and the salt water of the Atlantic Bay of Biscay create a complex estuarine mineral environment of exceptional tidal character. The medieval castle, the working oyster beds of Bourgneuf Bay, and the Atlantic thalassotherapy tradition create a Pornic experience of exceptional maritime cultural and therapeutic richness on Loire-Atlantique's most historically distinctive stretch of Atlantic coastline.
