Incredibly beautiful paths - partly on wooden planks, partly through fine sand. A small, hidden natural paradise that can be wonderfully explored on a circular hike.

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.
