The most heavily frequented tourist destinations and resorts in the Black Forest are the Titisee and the Schluchsee. Both lakes offer opportunities for water sports like diving and windsurfing. From Freiburg these lakes may be reached on the B 31 through the Höllental, via the Hirschsprung monument located at the narrowest point in the valley, and the Oswald Chapel below the Ravenna Gorge.
