Cross-trail Freiburg - Lake Constance: Mühlhausen - Singen

If you arrive by the regional train from Mühlhausen, follow the yellow diamond through Bahnhofstraße to Schlossstraße to the left, then climb straight on the right via the "Duchtlinger Steige" (1.5 km). At the "Mägdeberger Hof", continue the hike on the cross-trail towards Singen. Between Offerenbühl and Schüsselbühl, head straight towards the "Hohenkrähen". The gravel path first turns left onto a meadow path, which immediately changes to the right into a trail through a small forest. Upon reaching the archway to the outer castle, be sure not to miss the view from the Kegelberg (about 30 minutes). To do this, walk through the private castle yard and continue steeply up the rocky path secured with high-quality steel cables. At the top, you will be rewarded with a beautiful view of the Hegau and the upcoming stages, from Friedinger Schlössle to Lake Constance. Then the cross-trail turns south, leads to a parking lot and continues to the right to the Hotel Restaurant Hegauhaus. Head south towards the inconspicuous "Staufen". This phonolite mountain once also had a castle. Its sparse remains are not worth a detour. Therefore, at "Ettenberg" turn slightly left into the forest. Upon exiting the forest, you can already see the Hohentwiel ahead. Between them lies the A81 motorway, which has been tunneled underground for 700 m to preserve the landscape. We follow the gravel drive briefly to the left, then turn right onto a meadow path to climb to the junction "Alte Landesgrenze". Here the premium path Hohentwieler branches off to the right and leads as a panoramic path to the main entrance of the fortress, whose visit along with the view certainly forms the highlight of the route. We descend on an asphalted path to the Domäne (total 1 – 1.5 hours). To the left we go to the "Portal Hohentwieler" at the Domäne and further to the information center. Only there are admission tickets for the fortress sold! Straight ahead, the restaurant invites you to its garden terrace with panoramic views from Hohenkrähen to Lake Constance. To the right, the shady "ten Brink-Weg" leads through the forest down to the "Wiederholdweg". Passing left by the "Hotel Widerhold", we finally reach the former site of the Landesgartenschau with parking lot and the Regionalbahn "Seehas" stop. Those who still have enough time should not miss the nearby newly opened MAC - Museum Art & Cars. Its modern silhouette adapts to the curves of the Hohentwiel with its fortress ruins. In the museum, art and architecture combine with classic cars.
