Follow the hiking trail through the Rappertal, (trail no. 24), through the Katzenloch to the turnoff to the Rauthhütte. Follow the trail (no. 99) to the Rauthhütte. Then follow the forest path (no. 8) back to the starting point.
Tip: From the Rauthhütte it is worthwhile to hike even further to the "Zugspitzblick". (Walking time: approx. 20 minutes)
