When coming from the Frankfurt-Basel motorway, car drivers should take the Freiburg-Mitte junction and join the B31; when approaching Titisee-Neustadt they should follow the B500. If coming from the east, they should take the B311 from near Ulm or, from Stuttgart, follow the motorway in the direction of Singen as far as Donaueschingen. From the south they should come via Waldshut on the B500 to Höchenschwand.
You can reach Höchenschwand by taking the international Upper Rhine train line Frankfurt-Basel and changing at Freiburg onto the Höllentalbahn; at Titisee take the Dreiseenbahn branch line as far as the terminal, Seebrugg. From the south via Basel-Waldshut, Zürich-Waldshut or Konstanz-Waldshut.
