If you want to go to the watch tower from Klein-Umstadt or Groß-Ostheim or just want to avoid the less attractive ascent via the Radheim-Schaafheim connecting road, you can choose this option.
From the end of Mosbach, it leads over a cobblestone ascent to an asphalt path through the fields, until it finally goes in a nice bend (> 10%) up to the watch tower.
