The Opal Coast (French: Côte d’Opale) is a coastal strip in the former region of Nord-Pas-de-Calais in northern France. It extends over 120 kilometres of coast between the Belgian border and the border with Picardy. The Opal Coast is especially known for its imposing chalk cliffs: Cap Blanc-Nez and Cap Gris-Nez. But also the varied boulder-and sandy beaches surrounded by cliffs or dunes, picturesque fishing villages and impressive views. The different places are easily accessible along the D940 coastal road from Calais to Boulogne-sur-Mer offering a diverse range of stunning views.
