A canal towpath route connecting two historic (and alcoholic) provinces, Champagne and Burgundy. There’s a little climbing as you dodge the summit tunnel, but otherwise this is an easy, flat ride.
Aside from medieval Chaumont (with its fabulous railway viaduct) and the fine fortified town of Langres, there are few landmarks en route. Rather, the main appeal is the canal character and the many small villages you’ll pass.
With a little planning, you could extend the northern part of the route to Reims to link the two great regional capitals.
