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.

From the beautiful restaurant on the Bay of Authie, a narrow footpath leads past the small harbor of Madelon - and if the water is not too high, it even takes you the three kilometers to the bridge for pedestrians, cyclists and horse riders towards the Baie de la Somme.

The seals are there from two hours before low tide until two hours after. It's practically the only place to see them up close without disturbing them. They feel protected by the Authie River, which flows between you and them. Elsewhere, you must maintain a distance of 300 meters.

1891: after the death of the two doctors, a committee was formed in the country to erect a monument to them. Subscriptions poured in. Around 1892, the monument, in honour of the founding doctors of the Berck hospitals, was made by the sculptor Marie Cazin-Guillet (1844-1924), wife of Jean-Charles Cazin (1841-1901), a painter from Boulogne and brother of the doctor Henri Cazin (1836-1891). It was placed in front of the Kursaal gardens, on the Avenue de la Gare, and inaugurated on 23 August 1893. The monument was transferred to the municipality, which would be responsible for its care and maintenance. It remained in place until 1939 and was then dismantled; the round hump and the bronze bas-relief were hidden to prevent the material from melting during the Second World War. The various elements were found in the 1970s and 1980s and placed in different places: the bronze plaque at the town hall, the round bump on the Esplanade.
