Geosite details
The Slack River estuary and dunes form a vibrant ecosystem that spans more than 200 hectares. This site is the result of the interaction between the sea and the shore, providing a diverse habitat for many animal and plant species. The dunes, with their shifting shapes, are constantly changing and provide a refuge for specific flora, such as halophilic plants, adapted to the salinity of the environment.
Nearby, the Fort d’Ambleteuse, built in the 18th century, adds a historical dimension to the landscape. Its construction used local stones, strengthening the link between the built heritage and the geological resources of the region.
The Slack River estuary is also a prime location for birdwatching, especially during migration periods. Nature lovers will be able to spot herons, ducks and other aquatic species that frequent the area. This site is ideal for family walks, with rest areas and sea views, allowing you to fully enjoy this rich and varied natural area.
