Arcachon is a seaside resort on the shores of the Atlantic ocean. The spring of Saint Anne of the Abatilles has enabled Arcachon to become a health town with offering thalassatherapy and water cures. Discover the Arcachon basin, a tiny inland sea edged by the dune de Pyla, the largest dune in Europe. From the belvedère Sainte-Cecile, which towers over Arcachon, you can admire the superb view of the basin. On Bird Island, you can discover the cabanes tchanquees, small houses on stilts that are used by oyster farmers.
