Forest Lake Rehbach, Rieden
From Langenfeld you can reach the Waldsee Rehbach by foot. An about 7km long hike leads to the shore of the small bathing lake.
The "Riedener Waldsee", as it is also called, was created in 1982 and has since been awarded the title of "European Bathing Water". Numerous day trippers relax on the shore of the small lake in summer. Furthermore, the "Riedener Waldsee" is the starting point for the Traumpfad "Riedener Waldsee" as well as for the geological path "Riedener Kessel".
