Cayeux-sur-Mer is a kitesurf spot on the Picardy coast (Somme), south of the Baie de Somme. This shingle and sand beach on the Somme coast is well exposed to the dominant South-West and North-West winds blowing across the open English Channel.

Tidal spot with a good beach. Cayeux has a galets (pebble) beach in its northern section and sandy beach to the south. One of the more southerly spots on the Picardy coast, with a wilder and less touristy character.
