The biotope "Waldforum Roskerbach" in the Rosker Valley goes back to the former forest swimming pool Beulich, which was created by local citizens and opened in 1937. In 1986 the facility was renovated, but due to hygiene problems of the water it was closed in 1991. At the end of 2002, work began to renaturalize the site, restoring the natural stream channels and erecting several information stations. An ideal water playground.
