Danube
Central & Eastern Europe
The Danube is Europe's second-longest river, rising in Germany's Black Forest and flowing roughly 1,770 miles through ten countries before emptying into the Black Sea. It is the most-cruised river on the continent, linking the imperial capitals of Central Europe with the Balkans. Popular sailings run between Passau or Nuremberg and Budapest, with longer itineraries continuing on through Serbia and Romania toward the Black Sea, and seasonal Christmas Market cruises drawing visitors each winter.
Most first-time river cruisers start on the Danube's western half, between Passau or Nuremberg and Budapest, a stretch dense with imperial capitals, castle-topped hillsides, and vineyard villages that can be covered in seven nights. Continuing east past Budapest trades palace tours for a rawer, less-visited landscape — Serbia's riverside fortresses, Romania's Iron Gates gorge, and the wetlands of the Danube Delta — and appeals more to repeat cruisers looking for something less traveled.
Ports of Call
Passau, Germany
Set at the confluence of the Danube, Inn, and Ilz rivers, Passau is a common embarkation point for Danube cruises. Its Italian-influenced old town is dominated by St. Stephen's Cathedral, home to the largest church organ in the world.
Vienna, Austria
Austria's grand imperial capital offers Habsburg palaces, coffeehouse culture, and world-class classical music. Highlights include Schönbrunn Palace, St. Stephen's Cathedral, and the Ringstrasse boulevard that circles the historic center.
Bratislava, Slovakia
A compact and walkable capital, Bratislava's old town blends Gothic, Baroque, and Art Nouveau architecture beneath the hilltop Bratislava Castle, with easy access to the surrounding Little Carpathians wine region.
Budapest, Hungary
Split by the Danube into hilly Buda and flat Pest, Budapest is one of the river's signature ports. The neo-Gothic Hungarian Parliament Building, Buda Castle, and the city's historic thermal baths make it a highlight of most Danube itineraries, with many ships docking overnight to take in the illuminated riverfront.
Belgrade, Serbia
Serbia's capital sits at the meeting point of the Danube and Sava rivers. Belgrade Fortress overlooks the confluence, while the city's mix of Ottoman, Austro-Hungarian, and modern architecture reflects its long history at the crossroads of empires.
The Danube Delta, Romania
Near the river's end at the Black Sea, the Danube Delta is one of Europe's largest wetlands, a UNESCO-protected reserve of reed beds and channels supporting a huge diversity of birdlife, often visited by smaller excursion boats from longer eastbound itineraries.
