110 kilometers along the river is the Diemelradweg. Because it promises pure touring pleasure and was rightly certified by the ADFC with five stars as a quality route. The route takes you from the source of the Diemel River near Willingen-Usseln, past Lake Diemelsee and on through the historic town of Marsberg, the historic Hanseatic town of Warburg and other places that promise variety to where it flows into the Weser near Bad Karlshafen. A touring bike experience in a class of its own!
