From Parkeerplaats Spitzenberg-Michelbach-Baiershälde you roll straight into the Spitzenberg nature reserve, then on past the Ravensburg und Alter Berg reserve towards Kohlbachtal. Castles stack up nicely in the middle: Wasserschloss Menzingen, Schloss Massenbach, another Schloss and Burg Neipperg. The 73.1 km loop stays paved throughout and climbs 744 m before Haberschlachter Tal sends you back to the start.
