Ostweg
The Ostweg is a north-south long-distance path through the Black Forest from Pforzheim to Schaffhausen. The roughly 240-kilometre-long ridgeway was laid out in 1903 and has been managed and maintained since then by the Black Forest Club. Its waymark is a black and red diamond on a white background.
