I cycled to Schopfheim. An easy tour about 20 km one way. Going I went via Brombach. Coming back I cycled on the other side of the Wiese river via Lörrach-Haagen.
Riehen – Brombach – Steinen – Maulburg – Schopfheim – Haagen – Riehen
There’s one stretch between Steinen and Höllstein where the bicycle route follows the busy main road, B317. Loud and lots of fuel fumes and particulates.
I missed one turn-off between Maulburg and Schopfheim and cycled the path up to Wiechs instead.
Length: about 40 km
