If you like mountains, white-water streams and fir forests, then is this definitely worth a visit.
On the bottom of the valley you have two choices. One is the path next to the white water, which assume some good shoes. The other way is a bit more secure and easier, but not as interesting. About half of the trail lead the paths back together. You'll reached one of the highlights. A small water dam with a bridge, called "Barbarabrücke" and some water action!
The second half will be peppered with small streams and waterfalls, before you'll reach the meltwater source "Siebenbrünnen", where you can relax and picknick . In the summer a small restaurant is open.
If you still not do have enough, you can extend your trip easy. There are several places for example "Flueseeli" which are worthwhile to visit.
