With its 7200 hectares, the Bay of Somme is the largest estuary of the North of France. It is an unspoiled place composed of vast areas alternating between dunes, marshes and salt meadows. Situated on the route of the migrating birds, the Nature reserve of the Bay of Somme, and especially the Marquenterre park, is a peaceful haven for numerous wild birds stopping here to rest. The Bay of Somme also has the unusual feature of being home to a seal colony.
