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 😍🔝.

The duckweed covers the pond, what lies beneath remains a mystery.
