Resort description
Saint-Malo is a coastal city in the Brittany region of northwestern France, a port on the English Channel. This region has a temperate maritime climate: mild winters, cool summers and stable humidity. Combined with sea air rich in salts and iodine, these conditions have made the Brittany coast one of Europe’s leading centers of climatotherapy.
The Le Grand Hôtel des Thermes 5* complex is located on the Saint-Malo seafront, on the sandy Grande Plage du Sillon. The building was constructed at the end of the 19th century as a resort palace for patients undergoing sea bathing and climatotherapy.
The main treatment focus at Le Grand Hôtel des Thermes is thalassotherapy. These are procedures based on English Channel seawater, which is drawn from the area, filtered, heated and used in pools and treatment programs. The resort is suitable for patients who are recommended treatment and prevention of the effects of chronic fatigue, muscle tone and circulation disorders, recovery after physical and psycho-emotional stress, as well as general wellness programs based on thalassotherapy and marine climate.
