With a mountain bike, a short stop here by the water is worthwhile. The many water birds seem to be right at home here and give the section a calm, natural atmosphere. I stopped briefly, observed the animals, and enjoyed the moment on the bank – a beautiful natural spot on the tour.

When I cycle along the dam, I always come across different water birds. Whether in the water, when crossing the dam path, in flight... And it's always beautiful! On the east side of the Klingnau reservoir, there aren't so many water birds, and therefore fewer or no ornithologists or amateur ornithologists with their huge lenses and tripods. But there are lots of hikers. You come across skaters and joggers, especially when the weather is nice. And there's enough space for everyone here 😉😃!
