On the path leading to the footbridge, a park with benches is present, ideal for taking a break before taking the bike route de la Lys. For the monument, our grandfather Remi who fell on the field of honor at Verdun in 1916 is inscribed there, never forget 💮.

Very personal touch 😌, to say that I played inside as a kid... Still present today and may it remain there for a very long time. Wonderful childhood memory. to see out of curiosity when you follow this agricultural path.

Starting point for a walk along the Nieppe canal which opens into the forest. Historically: Vestige of this old railway line and presence of bunkers from the Second World War, in short, enough to make a beautiful hike.
