At the western end of the dam there is a beautiful lawn where you can swim. If you cross the dam and follow the narrow hiking path on the east side after the turnstile for about 1km, you will reach a small meadow. There you can also sunbathe naked in peace. When I visited in August 2024 there were only a few visitors and it was wonderfully quiet and relaxed.

It's great to walk the path here and have water on both sides. Interestingly, the fish ponds are located slightly higher than the Ilz.
