Roll out of Harbke and past Schloß Harbke, then into the Lappwald forest and the Elm-Lappwald nature reserve. The Aller river leads you to the Burgruine Weferlingen castle and on through the Rehm nature reserve. With 558 m of climbing, the windmill at Schernikau Ostingersleben is your last stop before rolling back to Harbke.
