The Untersee near Liblar is part of the Ville lake chain, a group of residual lakes that formed after early lignite mining on the Ville ridge. Unlike the heavily used bathing lakes in the surrounding area, the Untersee is a protected body of water that is not freely accessible. Older reclaimed forests, some of whose trees are now 30 to 70 years old, line its shores. The lake is ecologically significant primarily due to the presence of stoneworts, which are considered very sensitive.

Now every meter becomes a highlight again. Yes, almost every meter of the three lakes is great, but it is enough to capture the highlight of each lake.

One of the few benches that can be found around the Untersee. A nice place for a break...

Most of the pictures still show an old jetty that leads crooked and crooked onto the water. (Unfortunately) it no longer exists. It was replaced by a straight and shorter bridge. But it's still a nice place to unwind on the jetty...
