Rhine River 20 Castles Boat Tour Pass

 

Between Koblenz and Mainz, 20 castles stand lined up on both sides of the river. The best way to admire them is from on board the cruise ship, where you can hop on and off all day at 19 different stops and enjoy the riverside scenery with more than 150 possible departure times. You can spend as much or as little time as you would like at each stop, with the Rhine Pass being valid on all scheduled day cruises between Cologne to Linz and Koblenz to Mainz. There is a restaurant on board but food and drink is not included with the pass.
