Roll out from Parkeerplaats Steinbruch Gravenhorst and let the route unfold over 73.7 km, mixing paved and unpaved stretches as it goes. First up are the Dörenther Klippen, a nature reserve, before the Feuchtgebiet Saerbeck wetland reserve takes over the middle section. On you ride through the Mesumer Mark reserve and past Zachhorn, another nature reserve, with 388 m of climbing spread along the way. Then it's back to where you started.
