Sources Thermales de Saint-Martin-Vésubie

Sources Thermales de Saint-Martin-Vésubie in the Alpes-Maritimes department of France offers bicarbonate mineral spring bathing in the highest permanently inhabited mountain territory of the Mercantour National Park—a wilderness of granite peaks and deep valleys on the Franco-Italian border where the Bronze Age Valley of Marvels (Vallée des Merveilles), accessible by a three-hour mountain hike, contains over 40,000 rock engravings created by Neolithic and Bronze Age peoples on the granite slopes of Mont Bégo in one of the most extraordinary open-air prehistoric art sites in Europe. The bicarbonate mineral character of the spring reflects the granite and metamorphic rock geology of the Mercantour massif, where ancient crystalline formations create therapeutic mineral springs of genuine geological character within this exceptional alpine national park. The prehistoric rock art heritage, the Mercantour wilderness, and the bicarbonate spring tradition create a Saint-Martin-Vésubie visit of extraordinary prehistoric, natural, and thermal depth in the highest reaches of the Maritime Alps.
