Vennbahn cycle route and Eurovelo 5 - on excellent cycle routes through Wallonia

The Vennbahn is one of Europe's longest rail trail cycle routes at 125 kilometers. It runs from Aachen through a varied low mountain range landscape along the German-Belgian border through Eastern Belgium to Troisvierges in Luxembourg. From Aachen, the route steadily climbs slightly but almost never exceeds a 2% grade. Those who prefer to roll almost entirely downhill should start in Troisvierges (about 2.45 hours by train from Cologne). The route is car-free, excellently signposted, and offers cyclists more than just the finest asphalt under their tires: sights and bike-friendly accommodations nearby are marked, and information boards provide interesting facts about flora and fauna as well as the history of the old railway line.  The EuroVelo 5 (Via Romea Francigena) runs about 3,200 kilometers from England to Rome or from London to Brindisi on the southern Adriatic coast (3,900 kilometers). It crosses Belgium for nearly 400 kilometers – from Geraardsbergen in Flanders via
