Gems of the Danube with Best of Bavaria

Nuremberg commands the imagination on two levels: as the glittering medieval city where Holy Roman Emperors held court, Albrecht Dürer was born, and craftsmen produced the first pocket watch — and as the site of the 20th century's darkest chapter, where Nazi rallies and subsequent war crimes trials left permanent marks on European history and conscience. The Kaiserburg castle crowning the hill above the perfectly preserved old town offers sweeping views of a cityscape that, despite wartime bombing, remains one of Germany's most beautiful. The Documentation Centre on the former Nazi Rally Grounds is essential, sobering history; the Christmas Market on the Hauptmarkt, held since 1628, is among Europe's finest. Visit May through October or December.

Schwangau is a Bavarian Alpine village crowned by Neuschwanstein Castle, Ludwig II's fairy-tale masterpiece that inspired Disney's Sleeping Beauty Castle. Must-dos include touring both royal castles, riding the Tegelberg cable car for Alpine panoramas, and savoring Bavarian cuisine with castle views. May through October offers the best weather; winter brings magical snow-covered scenery.

Regensburg, Bavaria's medieval masterpiece on the Danube, is one of Central Europe's most intact ancient cities — its Roman origins visible in the Porta Praetoria stone gate, its medieval prosperity celebrated in the soaring twin towers of St. Peter's Cathedral and the twelfth-century Stone Bridge. UNESCO World Heritage status acknowledges a skyline dotted with patrician towers, while the famous Historische Wurstküchl, Germany's oldest operating sausage kitchen, has been serving spit-grilled bratwurst since the 1140s. The surrounding hills produce excellent Bavarian whites. May through September offers the most convivial riverbank atmosphere.

Passau occupies one of Central Europe's most dramatic natural stages — a narrow peninsula at the confluence of three rivers, the Danube, Inn, and Ilz, where the old town's baroque spires and shuttered merchants' houses crowd the very tip of the land between the waters. St. Stephen's Cathedral houses the world's largest church organ, a 17,974-pipe instrument whose daily concerts fill the nave with a sound that seems architectural in its density. The Veste Oberhaus fortress above the city commands panoramic views across three countries on clear days. Passau is a classic Danube river cruise departure point; spring and early autumn, when the river runs high and the light turns golden, are the finest seasons.

Schlögen, Austria, is a charming port town known for its breathtaking views along the Danube River and rich historical significance. Must-do experiences include savoring traditional dishes like Wiener Schnitzel and exploring nearby attractions such as Vienna and Dürnstein. The best season to visit is during the spring and summer months when the landscapes are vibrant and the local festivals are in full swing.

Dürnstein is the jewel of the Wachau — that UNESCO-protected stretch of the Danube where medieval villages, baroque spires, and precipitous terraced vineyards create the most picturesque river landscape in Central Europe. The blue-and-white tower of the Augustinian monastery and the dramatic ruins of the castle where Richard the Lionheart was imprisoned in 1192 define a skyline of romantic perfection. The surrounding vineyards produce some of Austria's greatest Grüner Veltliners and Rieslings; tasting rooms open directly onto the river path. May through October offers the finest conditions, with harvest season in September an especially memorable time to visit.
