The Naafbachtal between Kreuznaaf and Ingersauel is in good weather even with the Treckingrad well feasible. It is worth the short trip to the old watermill, which is now used as a youth hostel and where you are willing to show the visitor the old facilities.
From Ingersauel is the onward journey in the Naafbachtal to Mucher road, however, only recommended for mountain bikers. The path becomes narrow, rocky and in bad weather also very muddy. But the path is always charming.
