Welcome In Flanders Trails

At the very top of France lies a land to be discovered, a land of conviviality, mountains and tradition. Flanders, your new playground.

The Monts de Flandre, a land of conviviality where authenticity rhymes with good humour, a land of contrasts where the mounts follow the plains, a living land of traditions and festivities... a beautiful playground for sportsmen and nature lovers, the 1st cross-border Trail Area, on the Franco-Belgian mountain range.
