Fort d'Ambleteuse
Highlight • Historical Site
In 169, the English king James II, chased away by his subjects, came ashore in the already silted up harbour. When Napoleon planned an invasion of England, part of his fleet was located here. From the beach you have a view of the entrance to the port of Boulogne and in clear weather even of the English cliffs.

Family-friendly walk through a vulnerable dune area near the Slack river. Not suitable for wheelchairs. The route is well marked. The dunes themselves are not accessible due to their fragile nature, so you are obliged to follow the provided paths. The stretch of beach between Ambleteuse and Wimereux is impressive.
