145,000 hectares in size among which 30,000 hectares are wetlands, the Regional Nature Park of Cotentin and Bessin Marshes extends over two départements: the Manche and the Calvados. From the Vire and Douve marshes to the Veys bay, through the hedged farmland, dunes and moors landscapes, the Regional Nature Park of Cotentin and Bessin Marshes is a fantastic place to visit.
The park's visitor centre, Les Ponts d'Ouve, is located in Saint-Côme-du-Mont. Visitors can observe wild birds on the marsh from an educational footpath.
