Eternal Danube From Serbia to Germany With Main-Danube Canal

Situated along the famed Orient Express, where the Danube and Sava Rivers meet is Belgrade, one of the Danube's four riverside capitals. This is one of the world's oldest continuously inhabited cities—a place sieged, razed, and bombed by outsiders trying to control it. Today, the one-time capital of Yugoslavia is a thriving hub of government, finance, and urban renewal of many former communist-era districts. It is home to the Church of Saint Sava, one of the largest Orthodox churches; the famous Nikola Tesla Museum; Kalemegdan Fortress; and more.

Near the Serbian border, Croatia's easternmost city is known for its grit. During the War of Independence in the 1990s, it was almost completely destroyed after an 87-day siege. Vukovar rebuilt, and the Old Town is once again a magnet for guests from around the world. Highlights include the town's famous water tower, whose battered structure is a symbol of the proud Croatian spirit; the poignant National Memorial Cemetery of the Victims of Homeland War, the nation's largest mass grave; and elegant Eltz Manor, the 18th-century Baroque home of the Vukovar City Museum.

Kalocsa is one spicy city! The self-proclaimed "Paprika Capital of the World" is one of Hungary’s oldest cities, filled with historic buildings and quaint shops (selling paprika—what else?). Highlights include the 200-year-old Folk Art House, where local female artisans still paint furnishings, eggs, and other items in the traditional Hungarian way; the Paprika House, a museum dedicated to the legendary Hungarian spice; and the Archbishop's Palace with its 150-thousand-volume library of ancient books and manuscripts.

One of the most beautiful cities in the world, the wonders of Budapest rise up along both banks of the Danube in a truly impressive way. Along with Heroes' Square with its Tomb of the Unknown Soldier, awe-inspiring Hungarian Parliament Building, and the lavish Castle District with photogenic Fishermen's Bastion, the city is home to a captivating Jewish district and the second-largest synagogue in the world, an intricate underground cave system, and some of Europe's most famous thermal baths.

Bratislava is perfect for those who want to be transported to another time. Even from a distance, its 9th-century clifftop castle strikes an impressive pose. Down below, the bustling pedestrian-only Old Town is a charming collection of Old World architecture, like Michael's Gate, St. Martin's Cathedral, the Old Opera House, and the Neoclassical Primate's Palace. There's even a surprise or two, with Napoleon's cannonballs lodged in historic walls and an unexpected statue of Cumil the Sewer Worker peering up from below street level!

Vienna is a city that defies simple description. Over the centuries, it has been an imperial city, seat of the Holy Roman Empire, capital of the Austro-Hungarian Empire, and capital of sovereign Austria. Today, Vienna retains the grand Baroque architecture, historic style, and Lebenskunst (art of living) that attracted famous composers like Mozart and Strauss. It's a wonderland of lavish palaces and cathedrals, world-class museums and music venues, atmospheric coffee houses, and romantic fiakers (horse-drawn carriages) clip-clopping past it all.

If ever a town was the embodiment of quaint, it's Dürnstein. Sitting right at the entrance to the celebrated Wachau Valley, everything about this village is hospitable—even the vineyards extend right to the riverbanks to greet visitors. Highlights include the striking blue and white Stiftskirche, and the castle ruin looming over town that once imprisoned King Richard the Lionheart, according to legends. Welcoming shops and wine taverns serving up the Wachau's delectable wines and sweet apricots make this a wonderful place to spend time.

No visit to the Wachau Valley is complete without visiting Austria’s prettiest abbey. Built on a rocky promontory overlooking the Danube, Melk Abbey's origins date back to 1089. Today, it is one of Europe's finest examples of Baroque architecture, where Benedictine monks still farm the land and operate what is now the oldest school in Austria. Highlights include the library of ancient manuscripts, frescoed ceiling, stunning spiral staircases, and the ornate abbey church.

A technical stop on your cruise, Aschach is a small but important river port that serves as a hub for the transport of goods and passengers along the Danube. It is located on the river's northern bank, 9 miles (15 km) west of the Austrian city of Linz. In addition to its transportation role, it is also a center for river-related recreational activities such as fishing and boating, as well as hiking and cycling.

Situated along the Route of Emperors and Kings where the Danube, Inn, and Ilz Rivers meet, Passau was settled as early as the Neolithic Age. During the Renaissance, this City of Three Rivers was a major manufacturing center of swords, crafting bladed weapons stamped with the Passau wolf, which legend claimed would grant invulnerability. Today, the most famous sights lining the narrow cobblestone streets of the Old Town are the artistic Town Hall and the Baroque St. Stephen's Cathedral with its green-domed towers and one of the largest organs in the world.

One of the most beautiful cities in the world and Germany's best-preserved medieval city, Regensburg's unique UNESCO World Heritage is built on a legacy of aristocrats, bishops, craftsmen—and a sausage restaurant whose roots date back to 1146! Around almost every corner is evidence of the many cultures and influences that crafted this amazing city over the past 2,000 years. It's a haven of narrow alleyways, ancient fortifications, patrician houses, impressive churches, and a Stone Bridge that has spanned the Danube since the Middle Ages.

Tucked among the towering rock formations of the Danube Gorge is Kelheim, home to the Main-Danube Canal. An engineering marvel connecting the Main River to the Danube, the canal was completed in 1992, enabling river traffic from the North Sea to the Black Sea. Kelheim is also known for its colorful Old Town; Neoclassical Befreiungshalle (Hall of Liberation) monument commemorating Germany's liberation from Napoleon; 12th-century abbey; and impressive local breweries serving up their delicious Bavarian Bier!

Nuremberg combines Old World beauty with a complex past. Surrounded by 14th-century walls, its Old Town is filled with landmarks such as the fortified Königstor gate, Nuremberg Castle, and the 12th-century Church of St. Sebald. Yet the city is equally known for its 20th-century history: once a major center of Nazi power, it later became the stage for the Nuremberg Trials, where leading war criminals were brought to justice. Today, the Beautiful Fountain still draws attention at the city’s heart, its brass rings said to bring good fortune to those who spin them.
