Only about 60 kilometers are on the twelfth and last leg from Deggendorf to Passau. The three-river city is a worthwhile destination. The picturesque cityscape is characterized by baroque buildings and narrow streets. Matching Passau is also referred to as the Bavarian Venice. Among the special cultural monuments counts u.a. St. Stephen's Cathedral with the largest cathedral organ in the world. Tip: At the end of the tour, make a nice round trip on the Danube, which has accompanied you for so long.
