Dune du Pilat - Largest sand dune in Europe at over 340 feet high. At the top is a beautiful ocean view. The walk up can be tough, but well worth it. Beach is nice too, after that long walk a dip in the ocean is refreshing.

Arcachon - Town on the edge of the Bassin d'Arcachon. 45 minute drive from Bordeaux. My suggestion is a seafood meal in one of the beachfront restaurants. You get the best of France, great food and ambiance.
