The Fünfweiher is popularly called Feufweier. It was created in the 16th century for fish farming and irrigating the lower meadows. Later, it served as a fire-fighting water reservoir for the city of Lenzburg. In May, entire schools of tadpoles frolic beneath its surface. We have never seen such a high population of tadpoles in our lives. The pond offers the opportunity for barbecues and picnics.

The steep path to the quarry has been washed out and is very rocky due to the heavy rain in recent months. Each biker has to decide for themselves whether the stairs at the end of the trail are rideable.
