Roll out of Lüerdissen and let the ride unfold: first past Erichsburg castle, then on to Schloß Bevern. The middle section strings together nature reserves — Heinsener Klippen, Mühlenberg bei Pegestorf, Weinberg bei Rühle and Pöttchergrund — before the road turns you back toward home. It's 77.1 km, entirely on paved surface, with 761 m of climbing along the way.
