From the parking lot on the edge of Haller, this 10 km long hiking trail first leads on a long descent through meadows and forests into the Schwarze Ernz valley. With a bit of luck, you will see the famous Black Angus cattle along the way, which are highly valued by meat lovers far beyond the region’s borders. Through the beautiful valley of the Halerbaach with its impressive rocks along the stream, you finally return to the starting point.
