Started the ride in Donauschingen at the source of the Donau and followed the river to Vienna stopping in Sigmaringen,Ehingen,Lauingen,Ingolstadt,Regensburg,Deggendorf,Passau,Linz,Ybbs an der Donau,Krems and Vienna before getting the train back to Luxembourg via an overnight in Munich. The highlights of the trip were cycling through the Wachau region between Ybbs and Krems , the Melk Abbyand of course beautiful Vienna. Surpises were Regensburg and Linz, disappointments were Passau, I was expecting something more beautiful, this is where the Inn and Donau rivers meet.
