Roll out of Bad Frankenhausen/Kyffhäuser and let the route carry you along the Schleuse Artern, then beside the Unstrut itself. The Umfluter canal keeps you company before the Hackpfüffler See nature reserve opens up the way back. It's 71.3 km with 322 m of climbing, mostly paved with a short unpaved stretch. Then it's home to where you started.
