The Euro Velo 19 Meuse Cycle Route goes from the Meuse River's source in Pouilly-en-Bassigny, France to its mouth at the Hook of Holland.
Distance: The full signposted international route runs 1152 kilometres through France, Belgium and Holland. Through France you're looking at around 403km from Pouilly-en-Bassigny to the Belgian border just north of Givet, a wonderful traverse through the Champagne-Ardennes region and including the delightful Ardennes bike path.
Difficulty: This is an easy river route if you're following it from source to sea. It's suited to riders of all abilities, including families if you break the stages up into bite-size chunks. For a little more elevation, ride it in reverse.
