The park contains the site of Cap Blanc-Nez, which features some of the highest chalk cliffs in France at 134 meters.
The Audomarois marshes within the park are a UNESCO Biosphere Reserve, known for their traditional cultivation of cauliflowers and endives.
Cap Gris-Nez is the closest point in France to the United Kingdom, located only 34 kilometers from the English coast.
The park is home to a unique geological phenomenon known as the 'Boulonnais Jurassic', containing fossil-rich rock layers.
More than 300 species of birds have been recorded migrating through the park's coastal capes annually.
The park encompasses the 'Grand Site de France' label, designating the Capes area as a protected national landmark.
The landscape features traditional 'hedge-enclosed' farmland, known as bocage, which dates back centuries.
The park's wetlands support the rare Fen Orchid, a plant species strictly protected throughout Europe.
The Parc naturel régional des caps et marais d'Opale covers 132,000 hectares in the Pas-de-Calais department, spanning from the English Channel coast to the interior marshes and wooded hills. It is defined by the contrast between the limestone cliffs of Cap Blanc-Nez and Cap Gris-Nez and the low-lying wetland ecosystems inland. The park functions as a protected mosaic of habitats, including coastal dunes, peat bogs, chalk grasslands, and bocage farmland. It serves as a significant migratory corridor for birds and hosts a high concentration of rare orchid species in its calcareous grasslands. The landscape is shaped by the interaction of the Boulonnais hills and the coastal erosion of the Côte d'Opale. The territory encompasses over 150 communes, integrating rural villages with protected natural reserves. It is characterized by its geological diversity, featuring Jurassic-era cliffs and Cretaceous chalk formations.

Bring wind-resistant clothing, as the coastal cliffs are subject to constant, strong sea breezes.
Use the dedicated Maison du Parc in Le Wast as a primary information hub to pick up trail maps and current habitat status.
Plan for shifting weather patterns, as coastal conditions can change rapidly regardless of the season.
Attempting to climb or descend cliff faces outside of designated paths due to high risk of rockfalls and unstable soil.
Strict adherence to marked trails is required to prevent erosion of the sand dunes and protect sensitive wetland vegetation.
