Roll out from Parkeerplaats Trockenhänge bei Böttigheim and straight into the Trockenhänge nature reserve. Then it's castle to castle: Schloss Grünsfeld, Bettendorf'sches Schloss, and later the Burgruine Schweinberg, with the Naturpark Neckartal-Odenwald and the Geo-Naturpark Bergstraße-Odenwald along the way. Schloss Külsheim and the Laubertal nature reserve round things off before the loop returns to where it began. 75.4 km and 1039 m of climbing, almost all of it on pavement.
