What are some coastal areas near Amiens for camping?

The Somme River empties out into the Channel at the medieval seaport of Saint-Valery-sur-Somme, above which the Opal Coast stretches north in an expanse of sandy beaches, dunes, and white-chalk cliffs. Coastal campers will find plenty of spots around Boulogne-sur-Mer, Wimereux, and Équihan-Plage, from where you can hit the beach or head inland to explore the Caps et Marais d’Opale Regional Natural Park.
