Roll out from Parkeerplaats Halbtrockenrasen am Schwanberg and back again on 82.7 km of paved road. First up are two castles, Ruine Wässerndorf and Schloss Marktbreit, before the route slips into the Marktstefter Tännig nature reserve. Then it's reserve after reserve — the Mainaue zwischen Sommerach und Köhler, the Alter Main bei Volkach and the Astheimer Dürringswasen — with Schloss Schönborn and Schloss Crailsheim closing the loop.
