This route starts near the French border near Baden-Baden, where we cross the Rhine and follow the road south to Switzerland.

First we follow the Northern B500, better known as the Schwarzwaldhochstraße.

The name Schwarzwaldhochstraße was first used in 1930 after the completion of the section of the road between Hundseck and Untersmatt. The road made access to the high Black Forest easier. Under the Third Reich, further construction was done for strategic reasons, including completing the piece between Ruhestein and Alexanderschanze (between 1938 and 1941). The entire route from Baden-Baden to Freudenstadt was completed in 1952.

This road starts in Baden-Baden and rises quickly to the most important ridge of the northern Black Forest and reaches the summit at the Bühlerhöhe. In clear weather there is a wide view over the plain of the Rhine towards the Vosges.

From the Bühlerhöhe, the Hochstraße runs at an altitude between 800 and 1,000 meters above sea level.
At the bottom of the highest mountain in the northern Black Forest, the Hornisgrinde 1,164 meters high, the road reaches the almost circular Mummelsee, a kettle valley from the last ice age

The road then continues over the Schliffkopf and Kniebis, past Zuflucht and the Alexanderschanze to end up in the city of Freudenstadt.

We then follow the B294 and then continue on the B33 to follow the B500 back to Switzerland at Trimberg im Swarzwald. The remaining part of the B500 traverses the southern Black Forest.

We pass on the Titisee and the Schuchsee and the viewpoint Gupfen viewpoint. When the weather is nice you have a wonderful view of the Swiss Alps, the Black Forest, the Hotzenwald and the Rhine plain.

The route ends again on the Rhine, which this time forms the border between Germany and Switzerland.
