With some great day trip options available in the surrounding area, renting a car makes good sense. Without one, it’d be much more difficult to enjoy everything that Freiburg im Breisgau, 20 miles away, has to offer. Freiburg Main Cathedral, Schlossberg and Schauinsland Cable Car alone make the drive out here worthwhile. Don’t forget about Villingen-Schwenningen either! Just 30 miles away, Wanne Observation Tower, International Aviation Museum and Franziskaner Museum are non-negotiable stops here.
