The Musbachtal[1] is a small 2.6 km long steep and narrow carved valley with a creek at the bottom.

The valley stretches from the Carthusian monastery in Freiburg im Breisgau (Baden-Württemberg, Germany) to below the summit of the Roßkopf (Black Forest).

It begins below the Rosskopf summit at an altitude of 463 m and ends in Freiburg's suburb Waldsee (forest lake) at an altitude of 320 m. There is also the Vogelsanghütte (birdsong hut).

Through the lower part of the valley runs a way of the cross[3] which ends at the end of the valley at the St. Odile chapel.

In the 18th century eight stations of the cross were erected by Wolfgang Kleiser on the footpath which starts at the Kartäuserstraße (Carthusian street) and ends at the upper end of the valley in a clearing.
