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.

Hiking

Very varied path through the dunes of Slack. The path leads over dunes and through forests. It is partly sandy (suitable for barefoot running), partially fixed with boards. Leaving the trail is prohibited as the dunes are very fragile.

The Slack is a coastal river in France, which runs in the department of Pas-de-Calais.
He joins the Fort Mahon at Ambleteuse in the English Channel.
South of the Slack is the nature reserve "Dunes de la Slack" - with paved trails.
