Enjoy the hilly Eifel landscape around Kalterherberg on this approx. 21-kilometre route. You start at the Ruitzhof and ride past the Kalterherberg elementary school towards the Perlenbach and Fuhrtsbachtal nature reserve to the German-Belgian border. The nature reserve covers approx. 330 hectares and is one of the rare intermediate moors characterized by a constantly high and only slightly fluctuating water level. An impressive natural spectacle awaits riders in spring between April and May. Millions of blooming daffodils transform the gently sloping hillsides and the valley floor into a bright yellow carpet of flowers. The trail continues in a wide arc to the Fuhrtsbach stream and from here south along the stream. After crossing the stream over a bridge, you reach the Perlenbacher Mühle mill, where you can take a short break. From here, the route then heads back south/Kalterherberg along field paths at the western end of the nature reserve. After approx. 3 kilometers, turn right and follow the same route as at the beginning of the tour back to the starting point.
