Roll out from Parkeerplaats Krebsbachtal bei Kaichen and let the ride unfold: first past Burg Wonnecken, then through the Erlewiesen nature reserve and into Naturpark Hessischer Spessart. Later comes Schloss Philippsruhe, followed by the Im alten See nature reserve and two more castles, Leonhardisches Schloß and Degenfeld'sches Schloß. Along the way you pass the Krebsbachaue von Oberissigheim nature reserve. It's 73.8 km, all paved, with 560 m of climbing, and it ends back at the start.
