Unlock Free Transit with the Black Forest KONUS Guest Card
When you stay overnight in any of the 145+ participating Black Forest towns (such as Titisee-Neustadt, Hinterzarten, Triberg, Baiersbronn, or Gengenbach) and pay the small municipal visitor tax (Kurtaxe, ~€2.20–€3.50/night), your host gives you the KONUS Guest Card. It works as a free 2nd-class rail and bus ticket across the entire 11,000 sq km Black Forest region from Pforzheim down to Basel!
