It's always great there. As well as birds, geese and ducks, with a bit of luck and at the right time you can also see deer and wild boar. Today I saw a marten there for the first time, which was being attacked by crows.

The path directly at the eco-lake is considerably nicer than the parallel towpath.

Very nice new location with great stilt houses. Great location on the Saarschleife and definitely a dream in the evening.

If you come from the Saar Cycle Path with its concrete slabs, you can treat your joints to some "rest" here on the gravel.
