At the crossroads of dunes, marshes, and pine forests, the Marquenterre Park is a 260-hectare natural sanctuary, in the heart of the Baie de Somme. 🕊Here, hundreds of species of migratory birds stop over — and you can observe them from thirteen observation huts spread along an immersive six-kilometer route (with shorter options). 🔎 Whether visiting freely or on a guided tour, passionate naturalist guides share their knowledge with you, each season. 📸 The park also offers themed walks, photo and ornithology workshops to deepen the experience. 🚲 Good to know for cyclists: - Easy access via cycle paths (Baie de Somme, Le Crotoy…) - On-site bike parking, catering, nature shop/bookstore - Binoculars recommended (available for rent on site) 👉 A must-see for lovers of wild nature and wide open spaces.

You may walk with your dog to the beach but not further towards Le Crotoy. Protected nature reserve.
