Lake Spullersee stores water from the surrounding mountains to generate electricity in two hydroelectric power plants, the Braz power plant and the Spullersee power plant. This reservoir and the power plants are operated by the Austrian Federal Railways (ÖBB), so the electricity is used for the railways. According to the ÖBB, the frequency of the generated traction current is 16.7 Hz, while the grid frequency in Austria and Europe is 50 Hz. Lake Spullersee also serves as a flood protection facility.

The approach via the asphalted Spullerseeweg is the much more comfortable option compared to the very steep gravel path that leads from the other side over the Stierlochjoch to the lake.

Zug is the starting point for fantastic mountain bike tours, for example to Lake Formarin or Lake Spuller. A particularly beautiful loop is possible around Lake Spuller: take the road and the Dalaaser Stafel alpine pasture (https://www.komoot.com/de-de/highlight/2615746) to the lake, then continue along the lake and over the Stierlochjoch pass (https://www.komoot.com/de-de/highlight/7658010) to descend back to Zug on the other side: https://www.komoot.com/de-de/highlight/7658010. Of course, you can also ride the whole route in reverse, but that will be considerably more challenging!

After the Sonnenkopf cable car's last descent, there's a wonderful silence, and you almost have the large plateau to yourself. The occasional biker still to be seen 😅
