Unfortunately overcrowded on the weekends. Otherwise, but always worth a visit. The nature is really beautiful on the Kaltenbronn. In wet or even slippery but sure footwear is mandatory, as the wooden beams can be very slippery.
Impressive dam, it is also possible to walk around the lake. The Westweg long-distance hiking trail leads right past it. It is the largest reservoir in the northern and central Black Forest.
