From the parking lot in Winklen / Au near Längenfeld, follow the road in the direction of Winklen to the Rätselweg signpost. The path leads through meadows at the beginning, but leads straight into dense forest in which granite boulders as high as a house are scattered. Although the huge rock fall was 10,000 years ago, the traces are still clearly visible today. The geology is explained in a child-friendly way along the way. A walk-in witch's house should not be missing in a "fairytale forest". There is a natural water playground right on the lake that awakens the joy of playing in young and old. The descent is via the forest path or a forest path back to Winklen to the parking lot.
