One of the most beautiful routes in this area, definitely take your time and enjoy. In Lautern you will hear the babbling of the stream, look where the babbling is coming from and you will be amazed. After Lautern in the direction of Bermarningen, a narrow asphalt road awaits you that is very nice to ride. Car traffic is rare here. On the right side of the path the rocks are very close and with luck you will see the amphibians that live here in this habitat. Be careful, the path is uphill and oncoming cyclists are probably going fast, risk of accidents. Further up the bend it gets steep, I measured 11%. The path is not too long, you can also push, but definitely don't forget about the incline. Fantastically beautiful here and unreservedly recommended.
