생 레오나르도‬에서 가장 멋진 ‪6‬개의 천연기념물

Great view of Hardelot

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.

At the top of Mont Saint-Frieux, you will discover a hidden gem of the Opal Coast, offering breathtaking views of the English Channel and the surrounding dunes. You will also enjoy panoramic views that extend to the cliffs of Cap Gris-Nez and Cap Blanc-Nez on a clear day.

Dunes de la Slack

Dunes de la Slack is a beautiful nature reserve on the Opal Coast, between Wimereux and Ambleteuse. The area is named after La Slack, a river that flows through the dunes and flows into the sea at Fort d'Ambleteuse. The area is ideal for hikers and nature lovers. There are several walking routes available, including the 'La Baie de Saint-Jean' walk, which partly coincides with the GR120 du Littoral. The dunes are a varied dune area of the Parc naturel régional des Caps et marais d'Opale.

The panoramic board is nice to orient yourself.

Highest point of this dune walk with beautiful views of the canal, the dunes and Ambleteuse.

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.
