Very easy to drive path through deciduous forest. Upwards you can enjoy the murmuring of the brook, downwards you can enjoy the high achievable speed, gravel path without cross grooves.
Beautiful path in the Dernbachtal. You don't meet many hikers or bikers. It is worth taking a break at Karl's rest, there is a table with benches on the opposite side, right on the Grundbach and a small bridge.
