This loop, roughly around Bergstein and the Krawutschke observation tower, is short and crisp in terms of fitness with a strong main ascent between the Kalltal valley and the high-altitude villages of Brandenberg and Bergstein. You cycle clockwise, first relatively flat through the Kall and Tiefenbach valleys, then steeply up to Brandenberg and later very steeply down again to Zerkall. Here you will find the national park information point, which is also the start and end point of the route. Alternatives are the train station parking lot or the parking lots of the church in Zerkall or the parking lots of the Krawutschketurm in Bergstein.
