Cayeux-sur-Mer marks the start of your exploration of the Bay of the Somme. By way of introduction, stop at the Pointe du Hourdel and visit the Maison de la Baie de Somme here to learn about the many facets of the Somme Estuary. Scanning the horizon, you may be lucky enough to spot seals. Next, you ride along La Route Blanche, close to the sea, the dunes and stretches of pebbles, before a greenway provides an easy path to the centre of the resort of Saint-Valéry-sur-Somme, with its lively port and fishermen's cottages overseen by the medieval hilltop quarter. At this resort, it is possible to board the tourist train of the Chemin de Fer de la Baie de Somme, along with your bike, avoiding the cycle lane that runs beside the road up to Noyelles-sur-Mer. Finally, you reach Le Crotoy, a resort boasting unbeatable views over the Bay of the Somme.
