ADFC (German General Bicycle Club) certification
Cyclists depend on quality! The German General Bicycle Club (Allgemeine Deutsche Fahrrad-Club/ADFC) has assessed what cyclists can expect on-site, what the routes look like and where the service is good and has awarded its "ADFC Quality cycle path" ("ADFC-Qualitätsradroute") seal of approval accordingly. Ten criteria are included in the evaluation of a cycle path, including the route planning, the quality of the cycle paths and the tourism infrastructure. Based on these criteria, the cycle path is awarded the rating of 1, 2, 3, 4 or 5-star ADFC Quality cycle path. The certification is then listed for qualified tours.
