The imposing Gigerwald dam wall is located between the Mountain Restaurant Gigerwald and the Walser settlement of St. Martin in the Calfeisental. It is walkable (the road to St. Martin leads over it) and is located about 20-30 minutes by car from Bad Ragaz via Vättis

The central Mapgragg is located near Vasön, a little further ahead in the valley. On hiking maps, both reservoirs are clearly recognizable.
