Fuchslochtobel

Highlight • Gorge

Rustic ravine between Walzenhausen and Sankt Margrethen, in which a jungle atmosphere arises. A narrow bridge leads over the stream, which cascades down over a rock face in a kind of waterfall.

Highlight • Castle

Was my first small / easy hike with the help of komoot. To be honest, komoot is recommended, especially if you are not familiar with the area. Super thank you komoot.

After a pleasant, cool climb through the forest you reach the Burghalde with the Grimmenstein castle ruins. A wonderful view opens up of Lake Constance and the three neighboring states.
