After the sewage treatment plant, drive a short distance on the B317 towards Schönau, cross this after about 50m and continue on the Wiesental cycle path to Fröhnd.
When you arrive in Fröhnd-Unterkastel, take the first possibility on the right and drive past a riding stable towards the farm. We follow the “blue diamond” over a steep ascent to Hof.

You follow the Hirtenweg, enjoy the beautiful views of the Wiesental and continue to drive along the "Blue Diamond" to the Kammfichte. At the spruce, which has been standing for over 90 years, keep to the left in the direction of the pointer. When you arrive at the pointer, take the first opportunity to go down a short distance on the right. You meet again on a wide gravel path which you follow to the Hau hiking car park.
