Europe
Earth's second-smallest continent punches well above its weight when it comes to river cruising — most of the world's river cruise ships sail European rivers, and most first-time river cruisers start here. From the celebrated Rhine, Danube, and Seine to quieter alternatives like the Douro, Elbe, and Rhône, Europe offers the widest range of ships, itineraries, and sailing dates of anywhere in this guide, along with the added convenience of well-connected international airports at nearly every embarkation point.
The classic itinerary pairs castle-topped hillsides and vineyard villages with overnight stays in capital cities, but the differences between rivers are real: the Rhine and Moselle lean toward German wine country, the Seine toward Normandy and Impressionist art, the Danube toward Central European imperial history, and the Douro toward Portugal's oldest wine region. Sailing season runs roughly April through December for most rivers, with a dedicated market for Christmas Market cruises each winter on the Rhine and Danube.
