Approximately 800 miles long, the Rhine River is one of Europe's most important waterways, as well as one of its most popular rivers to cruise. With its fairytale scenery, complete with beautiful castles, medieval villages and lush vineyards, cruisers have plenty to enjoy on the river. Most one-week cruises travel between Basel and Amsterdam, seen here on the Rhine River cruise map, though there are many variables and add-on options for cruisers on the Rhine.A major highlight of a Rhine cruise is the 40-mile stretch between Rudesheim and Koblenz, which is a UNESCO World Heritage Site, rich with romantic castles and scenic towns. Other UNESCO World Heritage Sites include the Cologne Cathedral, the historic center of Strasbourg, Speyer Cathedral and Amsterdam's canal ring.
