Our hike starts in Aich at the village square. We start in the direction of Assach and pass the Ennsbrücke bridge. At the “Miller” junction, we turn left (in a westerly direction) and follow the road into the so-called Langtrum (view of the Aich leisure lake complex). At the Arnoldhof farm, take the left fork in the road and follow Langtrumstraße. Continue to the parking lot of the
single track. From there, a forest path leads us in a northerly direction. We walk through the forest along the Gradenbach stream to the Sonnberg crossroads. There we cross the road and take the next forest path. From there, the path leads us in a westerly direction over a small wooden bridge. From there we continue in the direction of Knerzlweg. Once we have reached this, we follow the path to the Sonnberg junction. (This is where the junction to the outdoor
Weißenbacher Kneippanlage is located) From this junction, the way back towards Aich runs in a south-westerly direction past the Bundesforstgarten.
