Roll out from Parkeerplaats Steinbruch Ehrleshalden and let the route unfold past the Saure Matten nature reserve and on to the Hohbergsee. Two watermills follow, the Hammerschmiede and the Historische Mühle Glatz, before the Schutter river leads you onward. With 76.7 km and 772 m of climbing, the loop returns through the Steinbruch Ehrleshalden nature reserve to where you began.
