In the 8th century, Emperor Charlemagne dreamt of a canal that could unite Europe's great waterways, but it was not until 1992 that his vision came to pass. Now, the Main-Danube Canal allows ships to travel directly from the North Sea to the Black Sea region, traversing Western, Central and Eastern Europe in a single journey. See the canals of Amsterdam, the castles of the Rhine Valley, great Danube cities like Vienna and Budapest, and many colorful capitals of Eastern Europe on an incredible 23-day cruisetour that includes eight countries on the Rhine, Main and Danube Rivers. New for 2013, this itinerary provides the ultimate European sojourn.
