This is how Viking River Cruises describes this cruise:
During this 8-day journey, encounter the grand cities and quaint villages along the celebrated Danube River. Explore both sides of Hungary's capital -- traditional Buda and more cosmopolitan Pest -- and from Fisherman's Bastion, see how the river divides this fascinating city.
Explore Vienna's imperial architecture and gracious culture, and tour riverside towns in Austria's Wachau Valley. In Germany, explore a baroque cathedral and stroll cobbled streets lined with half-timbered houses. Savor the tastes of authentic dishes, learn about local legends, and understand why Strauss immortalized the "Blue Danube" in his famous melody.
We will be on the Viking Bragi.
