From Gengenbach, the stage leads along the edge of the Black Forest and ends after 56 kilometres in Bühl.
The vineyards between the Rhine plain and the heights of the Black Forest are characterised by steep slopes. Castles such as Ortenberg (just before Offenburg) or Staufenberg (Durbach), fortresses and monasteries (Erlenbad, near Sasbach) bear witness to a centuries-old tradition and wine-growing culture.
In addition to wine, the seasonal variety of fruit and vegetables plays a major role, which is particularly noticeable around Oberkirch. This is also reflected in the distilling industry: there are over 7000 small distillers in Ortenau.
