This greenway allows you to cycle around the Bay of Somme from Le Crotoy to Cayeux, passing through the town of Saint-Valery-en-Caux. You can appreciate this remarkable natural site – to the north with the Merquenterre Regional Natural Park – its plant and marine ecosystems, and its rich birdlife. The greenway offers a suitable way to explore the area: gentle, sustainable, and in harmony with the environment and this preserved natural landscape. It's the perfect opportunity for an ecotourism holiday in accommodations that suit your needs (hotels, campsites, bed and breakfasts, holiday rentals, and unique gîtes).
