From the centre of Lech follow the road to Zug. After the village of Zug, the road joins a toll road (free for cyclists). Follow the asphalt road to the fork in the road. From here, turn left uphill to the Spullersee lake. Cycle around the lake and follow the road up to the Ravensburger Hütte. Pass the Alpe Brazer Staffel and continue uphill to the Stierlochjoch. From here you now head downhill over several serpentines and back to Zug. In Zug, pass the fish pond, continue briefly uphill and then turn right and return to Lech.
