This cruise showcases the majesty of three great European rivers — the Moselle, the Main and the Danube. Travel the man-made Main-Danube canal — a stunning technological marvel — as you transit from the beautiful Danube River. Explore the upper middle Rhine Valley with its numerous castles and experience the tranquil meandering of the Main. Discover the half-timbered buildings of Miltenberg and Wertheim, along with the UNESCO World Heritage Sites of Würzburg, Bamberg and Regensburg. Another sight of this cruise is the region that has been considered the best place for Riesling in the world: the romantic vineyards and villages of the Moselle river.
