Through Eastern Europe: Danube
The Danube, at 1,780 miles long, is the second-longest river in Europe. The river stretches through 10 countries, including Germany, Hungary, Serbia, Croatia, Austria, Slovakia, Romania, Moldova, Ukraine and Bulgaria, and famously flows through cities like Vienna and Budapest. Travelers can experience many of the river's sights by embarking on a cruise along its waterways. Danube River Cruises, which are offered by Viking Cruises, typically stop in Cologne, Budapest, Nuremberg, Belgrade and Krems. Following the river is a way to experience several Eastern European cities in one trip. Famous monuments, such as the Hungarian Parliament, have been erected on its coast.
Through France: Loire
The Loire River is one of several rivers that flow through France. This river runs east to west, splitting the country midway. It's part of the famed Loire Valley, an area famous for its local wines and historic towns. The region is easily accessible from Paris and well-known for its many castles, which include Chenonceau and Chambord. Many great wines come from the Valley, including Sancerre, a popular French white wine. Take a tour through the area or rent a car to experience it at your own pace. Be sure to make a stop in Amboise, a picturesque town built on the foundations of an old fortress.
Through Germany: Elbe
Once, the Elbe River helped form the border between East and West Germany; however, today, it flows through both Germany and the Czech Republic. It links popular destinations like Dresden and Prague and gives visitors views of German and Czech cities. Most cruises down the Elbe also bring travelers to lesser-known spots, such as Wittenberg and Meissen, and are an ideal way to experience German culture in a new way. Look for cruises that start in Berlin, located a short distance from the river, and end in Prague.
Through Western Europe: Rhine
The Rhine begins in Switzerland and streams 766 miles to Rotterdam in the Netherlands, where it ends in the North Sea. The river, known as "Old Father Rhine," runs past cliff-side castles, vineyards and, of course, picturesque towns that dapple the shores through six countries. Cities like Strasbourg and Cologne sit along the coast, making it an ideal journey for visitors to Europe. Companies like Viking River Cruises and Riviera Travel offer cruises along the waterway, most of which begin in Amsterdam. Look for the one that stops in your desired destinations.
Through Russia: Volga
The Volga is the longest river in Europe, stretching 2,294 miles across Russia. It flows from the remote Valdai Hills to the Caspian Sea, and half of Russiaβs river cargo is transported along the river. The waters of the Volga are used to irrigate the steppe regions of southern Russia. Because of its importance in the country, the Volga has mythological status in Russia, and many iconic sites are found along its banks. Travelers can cruise along the river during the warmer months of the year, usually from March until mid-December. Select one of Viking Cruises' Volga River cruises, which travel from Moscow to St. Petersburg, to see the best of the river.
