Andernos-les-Bains is a commune in the Gironde department in southwestern France. The commune is a level of administrative division in the French Republic. Communes have no exact equivalent in the United Kingdom, but are closest to parishes, towns or cities. Except for the municipal arrondissements of its largest cities, the communes are the lowest level of administrative division in France.
Andernos-les-Bains is a located on the northeast shore of Arcachon Bay. It is one of ten towns around the Basin and is very appealing to residents and visitors with beautiful beaches stretching 5.4 km (3.4 mi) of sand and safe waters, a promenade, pedestrian shopping streets, parks, swimming pool and it even has a casino. Tourism is a very important industry and the town swells with visitors in the Summer. There are fetes or festivals in Andernos nearly every weekend throughout the Summer.
Andernos-les-Bains consists of four other small communities: Taussat, Cassy, Lanton and Audenge. Like Andernos also, all these villages are characterized by their oyster farms and small fisheries. For many years, the oyster and fishing industry provided the main income to the area. As stated above, more recently, tourism has become a strong economic factor. The Archachon Basin oyster is a world famous delicacy and important to the area and the French economy. Since 2000, the oyster industry has been recovering from earlier setbacks and now nearly 15,000 metric tons are produced per year.
The closest airport is Bordeaux-Mérignac (30 km).
Sarah Bernhardt, a French actress, is known to have visited Andernos during the First World War.
