For me, the most beautiful natural swimming pond in the wider area. Very well maintained. Beautiful with blooming water lilies.

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.

A small footbridge leads us from one side to the other. It's lovely to stop on the footbridge and watch the flowing water.

I drove past first. I didn't regret my return trip! A beautiful little lake, Aaschächli, hidden and quiet. A little idyll. Unfortunately, I was there at dusk, so I couldn't see much, but I could still see and, more importantly, hear the birds landing on the water, seeking nighttime shelter. A perfect place to unwind. Thank you to the creator of this highlight 😍🔝.
