Starting in Loffenau, this forest road runs into the Schwarzwald (Black Forest). Initially, you can expect a pleasant easy ride, but after 2 km (1.2 mi) the steepness suddenly picks up and you've got a stiff climb.
There are several forest roads that intersect along its distance, and it terminates at a little forest hut where several trails intersect. If you want to continue climbing, Fadweg
is a good option.
