Passau, an unexpected surprise. This was our last stop in Germany before crossing the border into Austria. Lying at the confluence of the Danube, Inn and Ilz rivers, it is known as the Three Rivers City. Overlooking the city is Veste Oberhaus, a 13th-century hilltop fortress. The old town below is awash with baroque architecture and scattered with markets selling local produce – a great place to stock up before our next day of riding.
