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.

Silent, deserted, a testimony to the past.

Anyone traveling to Lake Hallwil should definitely pack their swimming trunks when the weather is nice. There are dozens of inviting and sometimes romantic places where water lovers can let off steam. The water is clear and warm! Barbecue enthusiasts will get their money's worth along the mostly wooded riverside promenade, as will nature lovers. Anyone who wants to fish can do so from the shore without hesitation. The Hallilwersee is of course also easily accessible by boat. The journey times are long and don't keep hikers/walkers waiting long. Hallwyl Castle is of course the star on the lake and certainly the number one tourist hotspot.
