From the Swiss border onwards, the Rhine forms a natural border between France and Germany. The Rhine Cycle Route follows the two banks for over almost 200 kilometres, alongside nature reserves and hydroelectric works, picturesque villages and Strasbourg – one of the capitals of Europe – before entering the German city of Karlsruhe. On the French side, the route is dotted with locks and typical Alsace villages with characteristic churches. On the German side, EuroVelo 15 passes through the Markgräfler Land, a renowned wine-growing region, and Rastatt, a town boasting magnificent Baroque monuments. There are several safe crossings over the Rhine to link the two French and German variants of the Eurovelo 15: the cycle bridges in Huningue, Chalampé, Strasbourg (3 bridges) and Gambsheim, as well as the ferries in Rhinau, Drusenheim and Seltz.
