7 Nights River Cruise, Europe

Vilshofen an der Donau is a town in the German district of Passau

Passau, a German city on the Austrian border, lies at the confluence of the Danube, Inn and Ilz rivers. Known as the Three Rivers City, it's overlooked by the Veste Oberhaus, a 13th-century hilltop fortress housing a city museum and observation tower. The old town below is known for its baroque architecture, including St. Stephen's Cathedral, featuring distinctive onion-domed towers and an organ with 17,974 pipes.

Despite its baroque architecture and historic old town, Linz is strikingly contemporary. The northern city hosts a cutting-edge cultural scene, exemplified by its futuristic electronic arts center and glass-fronted modern arts museum, both set on the banks of the Danube River.

It's been 200 years or so since he lived here, but Mozart is still very much Salzburg's favorite son. Visit the composer's residence and birthplace, then explore the Altstadt (Old City), taking in the baroque architecture. If your musical tastes run more "Raindrops on roses and whiskers on kittens" than "Requiem in D Minor," catch one of the many Sound of Music tours and follow in the footsteps of the Von Trapps.

Weissenkirchen in der Wachau is a town in the district of Krems-Land in the Austrian state of Lower Austria. The ferry across the Danube here is interesting in that it has no motor or sail: it is powered by rudder set against the river current, anchored to a cable above the river.

Austria's capital has always attracted artistic genius. Mozart, Beethoven, Schubert, Kafka and Freud were either born or moved here. Strauss waltzes and apple strudel are what come to mind to most visitors, but its most striking features are its Schwarzenegger-sized Alps and monumental Baroque edifices.

Slovakia's capital since the country's independence in 1993, Bratislava is a mosaic of illustrious history: a medieval and Gothic old town, baroque palaces commissioned by Hungarian nobles, and the crowning castle, rebuilt to Renaissance finery. Slicing through the city are stark-angled, communist-era blocks and a futurist bridge.

When overlooking Budapest from the Royal Palace wall or the Fisherman's Bastion of "Castle Hill," it's easy to see why Budapest is called " The Pearl of the Danube." Its grand buildings and beautiful bridges are architectural marvels, especially when the flood lights illuminate them at night. Hungary's capital has broad avenues, leafy parks and elaborate bathhouses and thermal spas. The River Danube serves as a good orientation landmark with Buda on the hilly left side and flat Pest on the right. The sights in Buda include "Castle Hill", Gellért-hegy and its prominent Liberty Statue, and the Citadella. Pest is the commercial center or downtown "Belváros" with highlights such as Vaci Street known for window shopping, fine restaurants and casual cafes.
