Roll out from Parkeerplaats Osterberg and the route unfolds through the Osterberg nature reserve before climbing on. Next up is the Steinbühl-Schäfergraben nature reserve, then a stretch through the Vorholz forest. With 58.9 km and 904 m of climbing, the mix of paved and unpaved keeps things varied under your wheels. The loop winds past the Albertskreuz nature reserve and returns to where you started.
