It remains a strange feeling to come across traces so long after the war.

Nothing really special. But worth a quick detour.

The traces of the Second World War are still omnipresent, even after 80 years.

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.

Le Hourdel is a picturesque place with a view of the beautiful Baie de Somme, Le Crotoy and the sandbanks where the seals warmed themselves in the sun. At least at low tide.

The bunker looks bizarre. Unfortunately it was high tide and no seals were to be seen
