The Rhine Valley or Middle Rhine (German: Mittelrhein) is the most famous section of the Rhine, running between the cities of Bingen(near Mainz) and Bonn in Germany and spanning the states of North Rhine-Westphalia, Rhineland-Palatinate and Hesse. The section from Koblenz to Bingen, known as the Rhine Gorge, is a UNESCO World Heritage Site, and the entire valley is often called "The Romantic Rhine".
