The Danube flows roughly 2,850 kilometres from the Black Forest to the Black Sea, through Vienna, Bratislava, Budapest and Belgrade. The classic short experience is an evening cruise in Budapest, past the floodlit Parliament and Buda Castle.
The UNESCO-listed river frontage: the Hungarian Parliament, the Chain Bridge, Buda Castle and Gellert Hill, Margaret Island and the Shoes on the Danube Bank memorial. Evening cruises are the signature trip.
Short trips on the Donaukanal and city reach, and day boats up the Wachau valley to Melk Abbey and Durnstein, a terraced-vineyard landscape that is a World Heritage Site.
Fast catamarans link Vienna and Bratislava in about 75 minutes, and multi-day river-cruise ships run Passau to Budapest and on to the Iron Gates gorge.
There is no single Danube authority; cruises are run by many private operators in each city. Short city sightseeing cruises are inexpensive and often walk-up; dinner, folklore and Wachau day cruises cost more and are best booked ahead. Confirm departure points and times with the operator you choose.
A one-hour Budapest cruise, a Vienna to Bratislava catamaran and a week-long cabin cruise are completely different trips. Pick the city and the length first.
The Parliament and castle are lit after dark and the short night cruises are built around that. Book a little ahead in summer.
From Vienna, the Melk to Durnstein boat through the vineyards is the most rewarding half-day on the river.
Where is the best place for a Danube cruise?
Budapest for the floodlit skyline, Vienna for day trips into the Wachau valley, and either as the start of a longer cruise.
Do I need to book a city cruise ahead?
A basic daytime sightseeing cruise can often be bought on the spot. Evening, dinner and Wachau cruises should be booked in advance in the busy season.
How long is a typical cruise?
City sightseeing cruises run about an hour. The Vienna to Bratislava boat is around 75 minutes. Wachau day trips take most of a day.
When is the season?
City cruises run year-round in Budapest and Vienna, with more departures from spring to autumn. Longer river cruises mostly operate April to October, plus Christmas-market sailings.
The Danube rises in the Black Forest in Germany and flows south-east for about 2,850 kilometres to a delta on the Black Sea, passing through or bordering ten countries and the capitals of Austria, Slovakia, Hungary and Serbia.
Long a trade and strategic route, it is now also a major tourism corridor, from short city sightseeing boats to a large international river-cruise industry. The riverbanks in central Budapest and the Wachau valley are UNESCO World Heritage Sites.
