The partially exposed mountain hike leads to the Sauerquelle and surprises with magnificent views.
A short ascent follows from the Brambrüesch mountain station. Then the path continues straight ahead through the dense forest. After a shorter descent, turn left and the path climbs briefly again. Now a narrow hiking trail follows, which descends towards Schönegg. In this environment one quickly dives into another world; dense vegetation and surprising views all the way to the valley accompany the hiker. Instead of going to Schönegg, turn right further down towards Sauerquelle. The water from the spring tastes quite acidic, but it is very rich in minerals and contains a lot of iron. The hiking path continues spectacularly through the flanks of the mountain massif with breathtaking deep views. Finally, one reaches a road, which one follows and at the end, after a short ascent, one reaches the middle station Känzeli. If you prefer to go up the route can also be reversed.
