You can enjoy beautiful views of the sandbank, which was first classified a nature reserve in 1972, either on a boat tour or from the top of the Dune du Pilat


The Banc d’Arguin is the largest sandbank off the Gironde coast, measuring 4 km by 2 km at low tide.

Located at the mouth of Arcachon Bay, its shape constantly shifts because of the tides. If you are lucky enough to set foot there, you will see busy oyster farmers and the perpetual ballet of sandwich terns and other migratory birds.
