페르네스 레 불로뉴‬에서 가장 멋진 ‪5‬개의 천연기념물

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.

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.

Frog pool where the planks are still flooded at high tide. Fortunately everything is well secured.

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.

Pointe de la Crèche is a nature reserve located at the northern entrance of Boulogne-sur-Mer. It is a protected area of landscape and cultural interest, made up of three parts: the point itself, the cliff and the plateaus, the natural and semi-natural meadows through which the coastal path passes, the old quarry now turned into a pond, and the fortress of La Crèche, a military heritage of the 19th century.
