An impressive stone monument with a large cross, located on the edge of the shipping channel of Grand-Fort-Philippe, near Gravelines. The calvary was built in 1947 to protect the fishermen and in memory of those who were lost at sea. Under the stone arch is a small chapel with a statue of the Virgin Mary and memorial plaques. Every year on August 15th, the place really comes to life: after the procession through the streets, the traditional boat parade stops here for the blessing of the sea. A quiet, atmospheric place to pause and reflect on the difficult fishing history of this coast, with a view of the channel and the sea. Feel free to combine it with a visit to the Musée du Sauvetage in the village.

A covered bird hide with a view over the reserve's ponds, ideal for quietly observing birds without disturbing them. Inside, there are large, clear identification charts to help you recognize what you see, including which months each species winters, migrates, or breeds here. On the ponds, you can see all kinds of ducks: dabbling ducks like the common teal, Eurasian wigeon, northern shoveler, gadwall, northern pintail, and common shelduck, and diving ducks like the tufted duck, common pochard, and common goldeneye. Along the banks, waders forage, such as the pied avocet, common redshank, Eurasian oystercatcher, northern lapwing, Eurasian curlew, and bar-tailed godwit. You can also encounter grey herons, little egrets, Eurasian spoonbills, great cormorants, greylag geese, and various gull species. Bring binoculars and give yourself time: the longer you sit still, the more there is to see. Especially during migration periods and in winter, the water is bustling with activity.

Beautiful protected nature reserve on the Opal Coast, between Oye-Plage and Grand-Fort-Philippe, managed by the Conservatoire du Littoral. Here, dunes, beach, salt marshes, ponds, and polders alternate, making it a top spot for birdwatchers. With a bit of luck, you can spot the pied avocet, little tern, Eurasian stone-curlew, common teal, or northern lapwing. Sea buckthorn grows abundantly in the dunes. A short loop trail starts at the parking lot along the ponds, and via the dune crossing, you can easily reach the wide beach. Definitely bring binoculars! The area is fragile, so stay on the paths and leave dogs at home or on a leash.
