Once flourishing under the protection of Waben Castle, the port of Madelon, with its medieval Berck fishing fleet, evolved into a marina due to the siltation of Authie Bay. Today, it has become a simple pontoon near a parking lot, but the setting remains very pleasant and the site is worth the detour!
