The Towns of Thuringia Cycle Route links seven of Thuringia’s prettiest towns, passing through some of the most scenic and historically fascinating parts of the region. This long-distance cycle route is particularly suited to touring cyclists and the culturally minded. As part of the D4 route, it is connected to Germany’s network of long-distance cycle routes and links Eisenach, home to Wartburg Castle, in western Thuringia and Altenburg, reputed to be where the card game skat originated, in the east.
