The Norman cliffs, about 65 yards high, date back to the cretaceous era (60 million years ago). These cliffs, visible from the “chemin des planches” (the planks path) contain a precious material: flints. Those flints would be rolled by the sea to become the blue pebbles you can find in the South of the Picard seaside.

The 14-kilometre-long beach of “Cayeux-sur-Mer” stretches from the south edge of the reasort until the tip of Le Hourdel.

The coast of Cayeux welcomes two species of seals: the Harbor Seal which is the most common with approximately 200 (in summer) individuals and the Grey Seal whose population amounts to around 25 individuals.

In the Middle Ages, the Ault harbour or " Hâble d’Ault» was an important anchoring area for the ships which could enter this zone by means of a channel that was connected with the sea.

Besides, Le Hâble d' Ault was considered as one of the biggest fishing centres of Northern France insofar as the quantity of fish gathered (soles and plaices mainly) was sizeable.

Several paths that have been laid out and are regularly maintained will allow you to discover this attractive place where the scents of pine trees and the wildlife meet.

At the north extremity of the beach of Cayeux-sur-Mer, you will find the tip of Le Hourdel which is the entrance for the boats that want to reach the Somme estuary.

The Bay of Somme is a member of the ‘Club of the Most Beautiful Bays in the World’, with its expanses of open water, marshes, dunes and saltwater meadows where the sea and the land seem to merge...
