The lagoon covers an area of between 40 and 155 square kilometres, depending on the height of the tide. You enter the lagoon from two ends, the Dune du Pilat on one side and Cap Ferret on the other, where you'll find the most beautiful beaches and the famous lighthouse. Depending on your point of entry, you'll have access to two types of beach: those on the ocean side and those on the dock side.
