The hiking and cycling path runs in a straight line alongside the Iller River. The path is gravelled and grassy in the middle. Alongside the cycle path, you can see the floodplain forest. Between the Iller River and the cycle path, there is a grassy strip about 3 meters wide. Wildlife can probably be spotted here frequently, as there is a hunting lodge in between. At least the fish were also taken into consideration at the weir. A fish ladder is located along the edge.
