Relax aboard your floating hotel as you glide gently along the picturesque waters of the Rhine, passing hilltop castles as you sail to the scenic Moselle. Highlights include the Roman fort city of Mainz, then Rudesheim, home to Drosselgasse, a winding street lined with taverns. Here you will also find Bromserburg Castle, a UNESCO World Heritage Site with two metre thick walls and a wine museum. Koblenz stands at the confluence of the Rhine and Moselle, and you can enjoy views of where the rivers meet at the Deutsches Eck promontory with its statue of Wilhelm I. We also call at the old town of Boppard with its medieval walls, picture postcard Cochem, and the typically German village of Alken.
