Danube Dreams for Wine Lovers (Westbound)

Divided by the Danube River, the Hungarian capital of Budapest -- known as the "Pearl of the Danube"-- is a city of two distinct halves. The hilly Buda side is topped by the impressive Royal Palace, home to several museums and charming cobbled streets lined with shops and houses that date to medieval times. On the busier Pest bank, there are grand sights like the parliament building, opera house and statue-lined Heroes' Square, plus fantastic shopping streets, such as Andrassy Avenue, Budapest's grand central boulevard. Several bridges cross the river, but the best one to use is the historic Chain Bridge, which is the oldest. The great thing about Budapest, a mainstay on most Danube River cruise itineraries, is it's compact, so you can pack plenty into a short break. The majority of sights are within walking distance or easily reached on the efficient tram and underground network. Coffee shops are a big thing. At one time, there were more than 400 in Budapest, so take time out to join locals for a caffeine boost and a slice of yummy cream cake. Budapest is also the world's only capital city to boast more than 80 active thermal springs and wells; soaking in the warm, mineral-rich waters is an authentic experience. Szechenyi is the largest, with indoor and outdoor pools, and Gellert is famous for its opulent -- and mostly original -- architecture. Many river cruise operators offer trips to the baths as an excursion option. Budapest's history dates to the third century, when Celtic warriors occupied the area. Study the place a bit, and you'll find yourself wondering: Who didn't invade the city? The Romans, Magyars, Mongols, Ottoman Turks, Austrians, Germans and Soviets have all played starring roles in Budapest's longstanding municipal drama. The city has been destroyed and rebuilt over the centuries -- part of the reason for its eclectic architecture, which includes everything from neo-Classical to Stalinist utilitarian. Its current skyline reflects the building programs and styles of the turn of the 20th century. As Claudio Magris wrote in his travel memoir, "Danube," "Budapest is the loveliest city on the Danube. It has a crafty way of being its own stage-set."

Bratislava, the capital of Slovakia, is an up-and-coming cruise port along the Danube River. It borders both Austria and Hungary, and it's located just miles from the capital cities of Vienna, Austria, and Prague, Czech Republic.

Visitors come to Vienna with high expectations of lavish palaces, ornamental parks, cakes piled high with whipped cream and the strain of Strauss waltzes. They're rarely disappointed; this is a city that trades on its glorious past, revelling in its heyday, when Gustav Mahler was conducting the Vienna Philharmonic, Sigmund Freud was inventing psychoanalysis and the coffee houses were abuzz with the banter of middle-class intellectuals.

Yet, as much as it lives in the past, Vienna has hauled itself into the present with elegance and style. Visitors will discover a compact but diverse, multicultural city, with a thriving art and design scene, some truly fabulous shopping, superb contemporary art collections, and acres of gorgeous parks and gardens. Here, you'll find a happy devotion to the good life, whether it's sipping a cocktail at one of the hip bars on the Danube Canal or the gemutlichkeit (the Austrian term for "cosiness") of tasting wines grown on the hills around the city in a traditional pub garden in the village of Grinzing.

Because most of the big attractions are around or inside the Ringstrasse, the circular boulevard that encloses the first district, or city centre, Vienna is easy to explore. In fact, you could spend days in the first district alone, shopping on the elegant Karntnerstrasse, exploring St. Stephen's Cathedral and countless other Baroque churches, devoting time to galleries and museums and immersing yourself in the famous coffee culture.

The many river cruise lines that call on the city provide a mere snapshot of this thriving centre of European culture with little deviation from the very well-trodden tourist trail. But Vienna caters to a diverse range of interests, and the good news is that if you come back for more, or want to explore it alone, the city is a snap to navigate independently.

Nestled along the Danube River in Austria, Wachau Valley boasts stunning landscapes that captivate visitors with its lush vineyards, rolling hills, and charming villages. This UNESCO World Heritage Site is renowned for its rich cultural heritage, medieval castles, and the remarkable Melk Abbey.

Melk, a quiet city, is located on the Danube River, just off the scenic Wachau Valley in Austria. Like many of the ports in this region, Melk's history as a city harkens back centuries, and this is apparent in the town's architecture.

For river cruise operators, Linz is used mainly as a waypoint from which shore excursions set off to other, grander locales like Salzburg, Austria or Cesky Krumlov, Czech Republic. And while the city is more of a place of work than a place to visit, it is a counterpoint to many other stops on a typical Danube River cruise itinerary. A quick tour through town (there really doesn't need to be any other kind) can provide relief for anyone suffering from "quaint European village fatigue syndrome." Linz is the third-largest city in Austria, with a population of 190,000 inhabitants; it's also the capital to the state of Upper Austria. Once known as the country's centre of industry (and hometown of Hitler), Linz is making a name for itself in the world of computer art and digital design. When you dock there, you will likely notice sculptures along the water's edge and a modern building with glowing LED lights, which is the Ars Electronica Center, a museum and development facility for new media arts. Also directly across from your ship will be Brucknerhaus -- named after composer Anton Bruckner -- a famous concert hall and home to the Bruckner Orchestra. The rising fortunes of Linz were officially recognized when the city was made a European Capital of Culture in 2009. Many cruise lines dock in Linz and offer shore excursions to nearby Salzburg, a couple hours away by bus. Salzburg is set in the forested foothills north of the Alps mountain range, and the Salzach River divides the city. The northeastern half of the city is the new town -- mostly businesses and transport links -- and the southwestern bank of the river is home to the charming Altstadt (Old Town) with its baroque churches and one of Europe's oldest medieval fortresses. Salzburg's Old Town was listed as a UNESCO World Heritage site in 1997. Home to Mozart, Haydn and setting of "The Sound of Music," Salzburg is a wildly popular stop for music-lovers of all kinds and tourists of all ages. In fact, the city gets 8 million visitors a year, an estimated 300,000 of which visit Salzburg each year simply because it's so prominently featured in the film musical "The Sound of Music." So soak it all in and sing it out loud while you're in town. Walk the Getreidegasse, a busy shopping street, and happen upon the house at number 9, where Wolfgang Amadeus Mozart was born. Pace the gardens of Mirabell Palace; "Do-Re-Mi" was sung on its steps. During the holiday season, enjoy the festivities and decorations of Salzburg's impressive Christkindlmarkt (Christmas market), and if you feel like singing a carol, the lyrics to "Silent Night" were written here, as well.

Arriving in Passau for the first time, you could be forgiven for thinking you'd landed in Italy instead of Germany. The city has a very Italian atmosphere that's led to its nickname, Venice on the Danube. And indeed, Passau was part of the Roman Empire for more than 400 years. When most of the city was destroyed by fire in 1662, it was rebuilt in Italian Baroque style, reflected in the vast cathedral, churches, squares and former homes of wealthy merchants. Today, as you stroll through the pretty streets, you'll notice a plethora of pizza and pasta restaurants rubbing shoulders with eateries that serve up hearty German fare.

While Passau has an undeniably touristy feel, it's a very attractive destination boasting a legacy of wealth built on the salt trade and, during Renaissance times, the crafting of knives and sword blades. The city occupies a unique location on the confluence of the rivers Danube, Inn and Ilz in south-eastern Germany, close to the Austrian border, and so it's also known as the City of Three Rivers. But the rivers haven't always been the city's friends: Passau has repeatedly been flooded by Alpine water swept along the Inn. High watermarks on the side of the town hall bear witness to the flooding; the highest date back to 1501, 1595 and 1954, the latter marked at more than 10m (32 feet).

Packed on a thin strip of land, Passau is easy to get around -- a major plus for visitors -- thanks to its small size. Beyond the long riverside promenade walk, lined with lookalike souvenir shops and some decent eateries, lies the picture-postcard old town, with traffic-free narrow streets made for meandering and many of the main sights. The sightseeing high spot, in more ways than one, is St. Stephen's cathedral, high up in the Old Town, home to the world's largest cathedral organ. Dominating the Danube side, opposite the dock, is the Veste Oberhaus fortress, which is now a multiple-choice castle containing a museum, youth hostel and restaurant.

Typically, riverboats dock in Passau after breakfast for a morning sightseeing tour, and passengers can opt to return for lunch back onboard or stay in town and have a meal independently in one of the many restaurants. River cruisers are then allowed free time to explore on their own before sailing in the late afternoon.

A popular embarkation port for Danube River cruises, the German town of Vilshofen provides a friendly introduction to the charming small towns that you'll encounter throughout your trip. The river is so important to the town that it's part of the official name: Vilshofen an der Donau, which translates to "on the Danube." (The river Vils, which meets the Danube here along with the Wolfach, is responsible for the first part of the name.) A Bavarian burg that dates back to 776, Vilshofen has a famous local son in Josef Groll, a brewer who is known as the "Father of the Pils." His beer, Pilsner Urquell, might have become famous in Bohemia, but it was Groll and his father who invented bottom fermentation. The resultant brew is considered the inspiration for two-thirds of the beer produced today. Often, river cruise lines feature the beer with pretzels and Bavarian music in a mini "Oktoberfest" celebration. The closest airport to Vilshofen is Munich, about 90 minutes to two hours away. Many river cruises offer transfers, either included in the fare or for purchase (if you go on your own, expect to pay at least 75 euros per person). Popular pre-trips for river cruises that begin in Vilshofen include Munich and surrounding Bavaria, or Prague, which is about three-and-a-half hours away. While Vilshofen is pleasant and worth a stroll, it's not a place where you need to stay overnight; you can arrive the same day your ship leaves and still see the highlights.
