Thermes Marins Arcachon

Thermes Marins Arcachon are located in Arcachon, a sophisticated Atlantic resort city in the Gironde department famous for the Arcachon Bay oyster industry — one of France's premier appellations for flat oysters (huîtres plates) and concave oysters (huîtres creuses) cultivated in the shallow tidal waters of the 156-square-kilometer bay — and for the astonishing Dune du Pilat at its southern tip, Europe's tallest sand dune at 107 meters, which continues to migrate slowly inland consuming the surrounding Landes pine forest at its rear face. The Arcachon Basin's unique combination of Atlantic tidal influence, Landes pine forest, and oyster-producing waters creates one of the most distinctive coastal ecosystems in France, protected in part by the Banc d'Arguin nature reserve. The thalasso marine spa here draws on the Atlantic seawater for a complete thermal experience, combining ocean mineral immersion with the pine-scented air of France's largest coastal forest, within a long thermal tradition.
