The region also includes the Ville-Seenplatte, a lake district formed from recultivated brown coal mining areas, offering a distinct landscape.
Among the most appreciated natural formations are the Katzenlochbachtal Stream, known for its wild and narrow brook valley, and the Hollow Way with Marl Outcrop, which offers a rare ravine formation. Another notable spot is the Geological Educational Trail: Venner Graben, a deeply incised stream valley formed over 800,000 years ago.
