The Main-Danube canal is a masterwork of engineering: It allows ships of all shapes and sizes to cruise from the Black Sea all the way to the North Sea, through no fewer than 15 countries. Sixteen locks punctuate the 106-mile (160-kilometer) stretch between Kelheim and Bamberg, linking the Rhine, Main and Danube rivers. Building the canal was no small task, especially considering changes of altitude (each river is different); the locks gently lift and lower the ships an astonishing 1,332 feet (406 meters) over the continental divide. Efforts to connect the rivers began with Charlemagne in AD 793, but the present-day canal was only completed in 1992. You have your choice of adventures in Regensburg, famous for its beautiful, UNESCO protected old city center. “Regensburg is so beautifully situated; this region had to attract a town,” wrote Goethe in his Diary of an Italian Voyage. And attract a town it did, but not due to its beautiful location alone. Ambitious and farseeing locals built a bridge (Steinerne Brücke, or Stone Bridge) over the Danube back in the 12th century, making Regensburg an international trading hub. Because so many of the handsome buildings from that period remain, UNESCO declared the old city center a World Heritage Site in 2006.
