The Arcachon bay

A r c a c h o n  B a y


Arcachon Bay is a bay of 155 km2 separated from the Atlantic ocean by the peninsula of Cap Ferret. The only access to the ocean is situated between the tip of Cap Ferret and the Dune of Pilat.


The river Leyre feeds the bay with freshwater. At low tide, only a quarter of this inland sea is covered by water.


This bay, simply called le bassin by the inhabitants, is well-known in France thanks to its oysters.


The Dune of Pilat, the Arguin sandbank and the Cap Ferret peninsula are all belonging to the Arcachon Bay area.
