100 000 years ago, the Côte d'Opale didn't exist. In its place there was a vast channel allowing boats to cross from the North Sea to the English Channel. Now the sea has advanced to the level of the Baie de Somme (Somme Bay). The different seaside resorts in the area attract holiday makers and offer a variety of sports and leisure activities : sailing, golf, tennis, kite flying...
