From Parkeerplaats Wallnau/Fehmarn you roll out for 61.8 km, roughly half of it unpaved. First up is the Nördliche Seeniederung Fehmarn nature reserve, then the Grüner Brink nature reserve, followed by the Kohlhofinsel nature reserve. You finish with the Krummsteert-Sulsdorfer Wiek/Fehmarn nature reserve before heading back to where you started.
