At the entrance to the village, cross the road and turn right into Am Rebberg on the opposite side. At the end of the street, turn left into Römerstraße and then right into Hofenackerstraße in the valley. A little later you pass the border. Cross a junction and continue straight ahead.

You now stay on Hegaustraße, which you use to leave the village again, passing below the church. Always following the ascending tarred road, you soon reach the Mägdeberg. At the top of the hill, turn left to the Mägdeberg castle ruins, which are well worth seeing. The legendary phonolite mountain, 664 m above sea level, is considered a place of worship for mother goddesses by the Celts. The castle was first mentioned in documents in 1240. In 1634, Mägdeberg Castle was burnt down by Widerholt. From 1650-53, Hans Jakob von Buchenberg rebuilt Mägdeberg Castle. The subsequent owners, the Counts of Rost, abandoned the castle around 1699 and built the castle at Mühlhausen, later to become the Adler Inn, as a replacement.
After the worthwhile visit, a tarred road leads you back downhill towards Mühlhausen (tip: a detour to the Hohenkrähen is possible halfway up). Shortly before the B 33, turn left onto a cycle path that takes you to an underpass. Cycle under this and into Mühlhausen. At a crossroads in the town, turn left into Ehinger Straße. Cycle over the railroad bridge and get into the left-turn lane after it to join the cycle path towards Ehingen. Shortly before Ehingen, turn right towards the Eugen-Schädler-Halle. Keep straight on for a while and then turn right after the first house. You now cycle past the Ehinger Ried nature reserve on the tarred road to Mühlhausen. Turn left at the town sign. A little later, the path runs parallel to the Saubach. At the next crossroads with a stone cross, continue straight on towards Schlatt and Krähen. After a poultry farm, keep left. In Schlatt u.

Shortly before the Aachbad, cross the river again and turn left again until you reach Schaffhauser Straße.
