Bassin d'Arcachon (44°42'N., 1°09'W.), an extensive landlocked basin, is mostly encumbered by muddy sand banks which are intersected by several narrow channels. A main channel, entered 3 miles S of Cap Ferret, leads through an inlet into the basin. Arcachon, an important center for deep sea and coastal fishing vessels, lies on the S shore of the basin. The area is a popular resort and there are extensive facilities for yachts and oyster boats. Constantly shifting sand banks ob struct the entrance and, especially after bad weather, occasion ally form substantial drying islands.
