Between Offenburg and Hausach, the Black Forest Railway follows the river Kinzig, and runs right next to it near Gengenbach. The section between Offenburg and Gengenbach is flanked by expansive vineyards, which slowly dwindle away as the Kinzig Valley narrows. The line then runs through the Gutach valley to Hornberg. From Hornberg to Sankt Georgen, the route must negotiate numerous loops, many through tunnels, and transcends several hundred metres in altitude in the process. This section is clearly visible from a lookout point near Triberg.
