Roll out of Wallertheim and the ride unfolds past the Aulheimer Tälchen nature reserve, then the Horn bei Siefersheim nature reserve, before Neu-Baumburg castle appears. Onward through the Haarberg-Höllberg and In der Au nature reserves, with Burg Stadeck as the last castle before the road turns home. It's 90.2 km, entirely paved, climbing 663 m along the way.
