The Rhine and Danube rivers do not meet directly at a common confluence, but they both flow through central and western Europe and are connected via a series of canals. The Danube River flows southeast from Germany through several countries before emptying into the Black Sea, while the Rhine flows north from Switzerland, through Germany and the Netherlands, and empties into the North Sea.
However, there is a notable point of connection between these rivers at the town of Kehl, near Strasbourg, France, where the Rhine serves as a natural border between France and Germany. Additionally, the Rhine-Main-Danube Canal, known as the European Canal, links the Main River (a tributary of the Rhine) to the Danube River, allowing for navigation between these major rivers.
Thus, while they do not meet in the traditional sense, the canals and tributaries create a network that connects these two significant rivers, showcasing the intricate system of waterways in Europe.
