Start/End in Passau, Vilshofen
We recommend you to go to Prague through CESKY KRUMLOV (Unesco Heritage). Cesky Krumlov is a quaint historical town with an amazing castle built by Lords of Rosenberg (1302-1602) and with picturesque medieval streets. You can see it in a day or in at night, both would be a magical experience. We strongly advise you to spent there a night or two.
