About eight kilometers long, mostly wooded terrain in the Bavarian foothills of the Alps between Föggenbeuern near Dietramszell and Egling, although I have not marked the piece between Egling and Thanning (because it is a road). You can roll wonderfully in both directions here, sometimes wider, sometimes narrower, sometimes rooty and there are also short pieces of tar.
The incision begins south of Föggenbeuern and meanders six kilometers almost due north, turning west near Fraßhausen and Wörschhausen. From here, at the beginning of the 18th century, the abbot of the Schäftlarn monastery created the three ponds in Thanning for fish farming. These are fed by the Moosbach, which rises in the Reichertshauser valley a few hundred meters above the first pond in the Frauenholz area. The valley ends in Egling.
