Nürnberg Heidelberg Vier Flüsse

A very nice 4 Rivers tour (on the way back, 2 more rivers were added) The Zenntalradweg, the Taubertalradweg, the Jagsttalradweg, and the Neckarradweg are all well marked. According to the odometer, it was 300 km. The first part, the Zenntalradweg, includes many detours and a lot of coarse gravel in places. The other cycling paths are made up of 90% asphalt and could also be easily ridden with a sturdy racing bike. 95% of the route is a real cycling path. No cars, often directly along the respective river, the paths are wide enough to ride two side by side (with oncoming traffic). In Zwingenberg (on the Neckar) there is even a ferry for cyclists. There are climbs only when transitioning to the Jagsttal (from Bad Mergentheim to Dörzbach), but even that remains moderate. The return trip can be found under Return Heidelberg-Nbg 3 Rivers. So the start is in Heidelberg!!! Or under Hochrad309!!
