Even in Flanders it's possible to hike through hilly landscapes for 175 km. on end! You don't even have to travel to Heuvelland in West-Flanders or the Voer region in Limburg. The centrally situated province of Flemish-Brabant offers everything you'll need. From the Hageland region, through forests and the Pajottenland region, this province has all it takes to get you from Diest to the Vlaamse Ardennen (Geraardsbergen) continuously going up and down. GR 512 has gathered it all into one impressive hiking trail.
