Starting point is the Erlebnis-Waldschwimmbad (adventure forest swimming pool). Shortly after the turnoff to the Erlebnis-Waldschwimmbad Kössen, we leave the Klobenstein road on the right and follow a meadow and forest path into the Schwarzwald (Black Forest). We hike above the Mühlberg stream, continuing on to the Ast zu Moosen-Alm. From there, we follow trail no. 21.
