Nearly every river cruise line sails on the Danube. It's one of the most popular river cruise itineraries and a great one if you're new to river cruising.
Most Danube River cruises either start or end in Budapest or Vienna, but the port city on the other end of the cruise can vary, usually depending on the length of the cruise. Shorter sailings tend to favor Nuremberg and Passau, Germany. A lower Danube cruise will begin or end in Bucharest, Romania.
Short Danube River cruises
If you're limited by time or budget, you can test the river cruise waters, so to speak, with shorter cruises. For instance, Avalon Waterways runs a three-night cruise from Budapest to Vienna, Austria.
Weeklong Danube River cruises
Seven-night cruises usually run from Nuremberg (after an overnight onboard) to Budapest. Port cities include Passau and Regensburg, Germany, and Melk and Vienna, Austria.
Lower Danube River cruise
The Danube consists of three sections -- Upper, Middle and Lower -- and while many cruises focus on the first two sections, you can cruise the Lower section through Eastern European countries. These voyages usually start in Budapest, traveling through Croatia, Serbia and Bulgaria before finishing at the Black Sea in Romania.
Longer Danube River cruises
If you want to spend more time on the Danube, you can find cruises that last anywhere from eight to 16 days, giving you a more extensive lineup of port calls. Some cruise lines even offer almost monthlong journeys that encompass not only the Danube but also the Main and Rhine rivers, allowing you to sail all the way from Bucharest, Romania, to Amsterdam.
Christmas Market cruises
Europeans do Christmas markets better than anybody else, which might be why these cruises are so popular. (Prices are often lower during this time, too.) Whether you're craving gingerbread cookies, handmade wood carvings or just hot sausage, you'll get your fill of old-world Christmas and maybe create new traditions with your family. These Danube River cruises sail in November and December and book fast, so plan early.
Cruise operators on the Danube include AmaWaterways, APT, A-ROSA, Avalon Waterways, CroisiEurope, Crystal River Cruises, Emerald Waterways, Grand Circle, Riviera Travel, Scenic Tours, Tauck, Uniworld, Vantage and Viking.
Each river cruise line has its own price point and level of inclusions.
