Schlossberg is a forested hill rising 456 meters above sea level just behind the Old Town. The Schlossbergturm observation tower offers breathtaking panoramic views of Freiburg's red rooftops, the Minster, and the Black Forest beyond. Accessible on foot via multiple hiking trails or by the Schlossbergbahn funicular. The summit features ruins of a medieval castle, forest walking paths, and a restaurant with city views.
