Roll out of Pfeffenhausen and let the route unfold: first the Abens river, then Schloß Ratzenhofen castle, before the Dürnbucher Forst forest swallows the road for a while. On the way back, Wasserschloss Train castle marks the final highlight before you return to the start. In total 69.1 km with 539 m of climbing, almost all of it on paved surface. A loop that strings together water, woods and castles.
