GR®121B

From Bailleul (France-Belgium border) to Rieulay (Nord)

The trail begins with the discovery of the Monts de Flandre (Flanders Hills), where the terrain rises gently above the coastal plain, offering panoramic views of a landscape of hedged fields and hop fields. This first section is marked by a strong Flemish identity, visible in the red brick architecture and the windmills that dot the ridges. Continuing south, the trail crosses the Lys Valley and enters the Scarpe-Escaut Regional Natural Park. Industrial and mining history then takes over from pastoralism: hikers discover a rich hydraulic heritage of canals and protected wetlands. The arrival in Rieulay, in the heart of the mining basin, is spectacular: the landscape is dominated by the Argiles slag heap, now converted into a protected natural area.
