The circular hiking trail leads you from the three-castle town of Riedenburg through the densely wooded "Klamm und Kastlhäng" nature reserve with its mystical gorge, past the Kastlhäng Cave, which served as a resting place for Stone Age hunters, and then to Prunn Castle, which sits majestically on a Jurassic cliff and is visible from afar. The trail leads back to Riedenburg along the forest and across a juniper heath, where, with a little luck, you might encounter grazing sheep, which also help preserve the unique natural landscape in the Altmühl Valley. Views of Prunn Castle, the Altmühl Valley, and Riedenburg make the hike an experience for the whole family.
