Thalasso des Sables-d'Olonne

Thalasso des Sables-d'Olonne in Vendée, France, offers iodine-rich Atlantic thalassotherapy at the port city that every four years becomes the most emotionally charged departure point in global sailing—the Vendée Globe, the world's most demanding solo non-stop around-the-world yacht race, sets off from Les Sables-d'Olonne to a crowd of hundreds of thousands of spectators, creating an atmosphere of maritime ambition and pure sailing culture that permeates the city's identity throughout the years between races. The iodine-rich Atlantic waters used in the thalassotherapy reflect the exceptional marine mineral richness of the Bay of Biscay off the Vendée coast, where the open Atlantic exposure and strong tidal currents create a particularly pure and mineral-concentrated seawater environment for therapeutic application. The Vendée Globe heritage, the powerful Atlantic surf beaches, and the iodine-rich thalassotherapy tradition combine to create a maritime wellness experience of exceptional sporting and oceanic character.
