Gigerwald Stausee

150-meter-high dam wall that can be walked on and driven over.

The Gigerwald reservoir is located in the Calfeisen Valley between rugged and steep rock faces that rise almost 2,000 meters into the air. At the far end of the lake is the tranquil Walser settlement of St. Martin. At the front, the water is held back by a dam wall almost 150 meters high, which can be walked on. The Sarganserland KSL power plants have been producing 460 million kWh of electricity here every year since 1976.

The water comes from the Calfeisen Valley and the neighboring Weisstannen Valley, is collected in the Gigerwald reservoir, and is turbined in the Mapragg power station near Vadura and Sarelli near Bad Ragaz.

Guided tours are available on request through the Mapragg power station and the Gigerwald dam.
