From Rahden the route continues through Oppenwehe to Levern. In the vicinity of Oppenwehe is the Oppenwehe Moor. Its next goal, opposite the Wiehen Hills, is Preußisch Oldendorf, a town with three state-approved climatic health spas. A special route links the palaces and manor houses around the town. From here the cyclist must choose whether to follow the northern variant or southern variant of the Mill Route.
