Regensburg, Rüdesheim, Heidelberg and Maastricht – all are very old and have many stories to tell. One minute you are in the middle of a bustling plaza, and then seconds later you are in a quiet avenue. The rivers themselves should not be forgotten. They all have their own character and charm; from the vineyards of the Rhine, Main, Danube and Moselle
, to the countless castles we sail past.
