Tucked away in the heart of Normandy lies a hidden gem for nature lovers and history buffs alike — the House of the Regional Nature Park of Cotentin and Bessin Marshes (La Maison du Parc naturel régional des Marais du Cotentin et du Bessin). Located in the small village of Carentan-les-Marais, this enchanting site invites you to explore the rich landscapes, wildlife, and traditions that define one of Normandy’s most unique ecosystems.
🏞️ What is the Regional Nature Park?

The Parc naturel régional des Marais du Cotentin et du Bessin spans nearly 150,000 hectares across the Manche and Calvados departments. Created in 1991, the park was designed to protect the marshlands, preserve biodiversity, and support the rural communities that thrive here.
The park is a patchwork of canals, rivers, wetlands, bocage fields, and meadows — home to migratory birds, rare plant species, and a tranquil pace of life. And at the heart of it all stands the Maison du Parc, where your journey into this living landscape begins.
🏡 The House of the Park: A Gateway to Discovery
The Maison du Parc is housed in the beautiful Château de Les Vaux, a restored 18th-century manor surrounded by meadows and water. This visitor centre serves as the information and interpretation hub for the park, providing fascinating exhibits and activities to help you understand the history, environment, and traditions of the Cotentin and Bessin region.

The Maison du Parc helps you understand the delicate balance between nature and farming, between preservation and progress.
