The mountain path single trail leads down through typical Jura soil, moderately steep to steep. The ground alternates between soft and hard and you drive over stone blocks, fist-sized, partly loose stones and roots. At the top it starts at Burgbüelstrasse and at the bottom it ends at Grasrüttistrasse. After a quarter of the route you cross the mountain path. Therefore the name.
If you want to pedal from the bottom up, you will probably reach your limits. Even with an eMTB.
