Sail deep into the heart of Europe on an epic 21-night river cruise from Amsterdam to Bucharest. Begin among Amsterdam’s canals before tracing the Rhine and Main rivers past Cologne, the Rhine Gorge and medieval towns such as Rüdesheim and Miltenberg. Continue through Bavaria to Austria’s Wachau Valley and Vienna, then linger in Budapest before venturing beyond the traditional Danube routes into Croatia, Serbia, Bulgaria and Romania. Explore grand capitals, baroque abbeys and World Heritage towns, meet local families in rural villages, and cruise the dramatic Iron Gates gorge.
