Starting in front of the station building in Rottenburg, the Schönbuch Nature Park - Round of Castles & Palaces - Tour leads about 100 meters down Bahnhofsstraße to the north. From the signpost at the first intersection, the tour follows the district's official cycle path signs and is marked with the red castles and locks inset. Cross the flat field and the suburb of Kiebingen to Bühl, where the Bühler Castle is already approaching from the town entrance see is. It served as a model for Hirrlingen Castle, which is part of the circuit through the Upper Neckar Valley and is just over ten kilometers away. From the field path between Bühl and Kilchberg, when the visibility is good, there is a double view of the castle, both of the castle complex in Kilchberg as well as Hohentübingen Castle some distance away. Along the property of Kilchberg Castle, the tour runs over a level crossing and through the wide Neckar Valley to Tübingen. When you arrive in Tübingen, the route leads past the outdoor pool and through the park to the Neckarsteg, from which Hohentübingen Castle seems only a stone's throw away. The pedestrian and bicycle tunnel through the Schlossberg is the fastest connection to the old town of Tübingen. On hot summer days, the tunnel with its consistently cool air offers a short refreshment. At the other end of the tunnel, there is the option of a short detour on foot up to Hohentübingen Castle. A small, steep path leads in two bends up to the fortress-like complex. For a short excursion into the center of Tübingen's old town, it is advisable to lock your bike to one of the many bicycle racks and explore the pedestrian zones of the city center on foot, past the Jakobuskirche and the historic one Nonnenhaus, the route runs along the Ammer in a large arc around the Österberg. In the Lustnau district, where the Goldersbach flows into the Ammer, there is the option of shortening the route by around 20 kilometers and heading directly to Bebenhausen Castle. Follow the regular cycle path signs in the direction of Bebenhausen. The complete tour leads down to the Neckar and then on the Neckar valley cycle path through the Neckar valley, which is very wide in this section, to Kirchentellinsfurt. There follows the most demanding ascent of the tour up to the extensive plateau of Einsiedel in the Schönbuch nature park. An avenue leads to the small town of Einsiedel, at whose northeast end the ducal domain of Einsiedel Castle can be found. A hiking rest stop is operated here on Sundays and public holidays. The tour continues through the Schönbuch Nature Park, first over the field and later through the forest to the beginning of the Kirnbach Valley, one of the most beautiful valleys in Schönbuch. After crossing the Rotwildgattersperre of the nature park, the valley continues gently downhill for six kilometers to the Goldersbach. On the way there is a spacious rest area with a barbecue area about halfway up. When you reach the bottom you can see the monastery and castle Bebenhausen, which is harmoniously located in the middle of the nature park and offers a variety of sightseeing opportunities, just a few pedal steps later. From Bebenhausen, the route follows the course of the Goldersbach and later the Arenbach upstream. At the Triangle Garmerklinge, where there is also a rest area with a barbecue area, the tour branches off to the right and follows the side valley with a moderate gradient uphill to the highest point of the tour: the royal hunting lodge in Schönbuch. From the hut at 536 meters you can enjoy a view of two well-known landmarks when the view is good. On the one hand, the Wurmlinger Chapel - the landmark of the Tübingen district - can be seen through the trees. On the other hand, you can see the striking silhouette of Hohenzollern Castle on the horizon. Through the forest of the nature park, it goes downhill again to the Entringen car park and from there slightly uphill to Hohenentringen Castle with an excellent view of the Ammertal and first-class excursion gastronomy. It is only a stone's throw to the next castle: past a horse farm, the tour leads along the Schönbuchtrauf to Roseck Castle, which towers over Unterjesingen further across the field to Poltringen. At the end of the village, the Moated Castle Poltringen awaits, surrounded by a moat, is nestled on the back in an almost fairytale landscape of wild brooks and plants. The tour continues upstream along the Ammer, past the impressive lake of the Reusten quarry and behind the village Short but steep ascent towards Oberndorf on the fields. From the fields in front of Oberndorf there is a fantastic view of the Ammertal with Hohenentringen Castle, Roseck Castle, as well as the Wurmlinger Kapelle. On a gently sloping route, the tour leads from Oberndorf via Wendelsheim back to Rottenburg, where you can explore the episcopal city.
