Founded by the Celts over 2,000 years ago, Passau is one of Bavaria's oldest cities. Known as the "City of Three Rivers,” it rests at the confluence of the Inn, Ilz and Danube rivers. The city has long enjoyed its strategic position and grew to great economic and political power because of it. The legacy of its past prosperity lives on in graceful arcades, colorful houses with rococo facades and the glorious baroque St. Stephen's Cathedral, home to one of Europe's largest pipe organs. Passau is also where two nations meet; it is here that the German-Austrian border begins.

Linz is today's provincial capital of Upper Austria. The city's famous Linzer Torte, the jam-filled cake topped with almonds, hails from here and can be found in any number of cafés and the stalls of the city's Christmas markets. In the Old Town, the baroque architecture of the main square provides a stunning backdrop for its Christmas market as the scent of gingerbread fills the air. At the Volksgarten, a nativity scene provides an atmospheric feature with the sounds of classical music and moving figurines that tell the story of the birth of Jesus Christ.

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.

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.

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 Christmas season adds another layer of beauty to the already romantic charms of Budapest. Nestled in the heart of Pest lies Vörösmarty Square, home to the city's largest yuletide market. The enticing aroma of national specialties permeates the air as vendors display traditional and contemporary handicrafts. At the cozy St. Stephen's Basilica market, mulled wine keeps revelers warm as nightly light shows illuminate the church's facade. Across the Danube in Buda, Old-World allure mingles with festivities in Fő Square, where seasonal events and an outdoor ice rink entertain.
