The Crotoy municipal marsh is often compared to a miniature version of the Camargue, offering a panorama rich in biodiversity. This natural space promises a total immersion experience for flora and fauna lovers. Don't forget your binoculars to better observe the various species that make their home there, such as storks, swans, ponies and Highland cows. It is also possible to hear or see the green tree frog, an amphibian characteristic of this region.

Parc du Marquenterre

Highlight • Natural

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.
