Between the English Channel and the North Sea, the Regional Nature Park of the Opal Capes and Marshes is an idyllic natural attraction in Pas-de-Calais. This protected area is characterised by a great diversity of landscapes, shaped over the centuries by its inhabitants. To the west, the coastline - defined by the Opal Coast - is a series of dunes, estuaries and sandy bays. Not to mention the spectacular wilderness site of the Capes, which includes two gigantic cliffs, Cap Blanc-Nez and Cap Gris-Nez. Inland, in the Boulonnais region, lies the rural heart of the park, alternating between hedged farmland, green valleys bordered by steep limestone hills, forest massifs, the Artois hills and charming villages. Finally, to the north-west of the park, the Audomarois Marshes form a remarkable natural area, the very last cultivated marshland in France.
The Regional Nature Park of the Opal Capes and Marshes also has a fine cultural heritage represented by stone manors, white chalk houses and cob longhouses. Numerous marked trails criss-cross the park, allowing hikers to explore a well-preserved natural environment.
