Riverside beauty and a vibrant cultural scene blend together in Budapest to form one of Europe's most rewarding cities. Hungary's enchanting capital straddles the banks of the Danube, with traditional hillside Buda on one side and modern Pest on the other. By day, stunning art nouveau buildings, stalwart castles and grand palaces set the stage for inspiring strolls and long soaks in thermal spas. By night, the shimmering lights of the Parliament building dance across the waters of the Danube, the Chain Bridge uniting it all as a dramatic centerpiece.

Take in the natural beauty of the fabled "Blue Danube” as you pass through the Danube Bend, considered one of the most beautiful sections of the river. Cruising this 40-mile stretch through northern Hungary, you will see peaceful farmland and an ancient castle that once served as hunting grounds for royals and visiting dignitaries. As you sail the passage between the Börzsöny and Pilis Ranges, you will marvel at the steep hills draped with bucolic forests. And delight in the majestic church domes peering at the waterway from inviting villages and historic cities.

The yuletide season transforms Vienna's beautiful squares into delightful Christmas markets. Festive lights illuminate the Old Town. The Schönbrunn market, set in front of the baroque Hapsburg summer palace, and Freyung market, nestled in the city center, are the perfect destinations for unique handmade decorations. Seasonal music and choral singing provide a merry ambience to holiday festivities in Am Hof Square, while the market at Belvedere Square mixes excellent shopping opportunities with views of the stately palace and adjacent lake to create a fairytale atmosphere.

Vienna is considered one of Europe's greatest cultural hubs. Its art scene has long been established with the Hapsburg's collection of fine art, now housed at the Kunsthistorisches Museum. Today, Vienna's modern side showcases street art murals that don the side of buildings along the banks of the Danube. Ingrained in local life is the long-embraced tradition of coffeehouses; UNESCO includes Viennese coffeehouse culture on its list of Intangible Cultural Heritages. It is considered one of life's pleasures to while away an afternoon over an Einspänner coffee and a pastry.

Sail through a scenic tapestry of hillside vineyards, charming towns and castle ruins in Austria's Wachau Valley, celebrated as perhaps the most scenic stretch of the Danube. Journey 18 miles through this vast UNESCO World Heritage Site, where the river courses through idyllic countryside hamlets. Gaze upon the hibernating, wine-producing villages-the legacy of vintners that stretch as far back as Celtic and Roman times and an echo of the more than 30 monasteries that served as vineyards in Renaissance days.

Centered around the beautiful St. Stephen's Cathedral, home to Europe's largest pipe organ, the romantic market stalls of the Christkindlmarkt are a delight to explore. An array of handmade goods, from tasty treats to ornaments, offer a wealth of opportunity to take home a unique artisan gifts created by local craftsmen. Periodically throughout the festive season, the cathedral hosts yuletide concerts; the sound of choirs singing can be heard as their voices echo through the courtyard and the town's narrow streets.

The UNESCO World Heritage city of Regensburg is transformed during the holiday season as its medieval streets are donned with festive cheer. Narrow passageways open to hidden courtyards with stalls laden with handcrafted wares, including dolls, pottery and silk paintings. The scent of home-baked spiced gingerbread, cinnamon and glühwein fills the air. The world-famous boys' choir, the Regensburger Domspatzen, was formed at the city's cathedral in 975 and travels the globe, performing to admiring audiences internationally.
