The karting starts the quiet “chemin des mottes et du Royon”, heading towards Groffliers through the pastures!

Once flourishing under the protection of Waben Castle, the port of Madelon, with its medieval Berck fishing fleet, evolved into a marina due to the siltation of Authie Bay. Today, it has become a simple pontoon near a parking lot, but the setting remains very pleasant and the site is worth the detour!

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.
