The Holenweg Trail is the logical route to the Weisse-Wand Trail. In contrast to the Naturfreundeweg, it is drivable throughout. The single trail leads steeply upwards, so you have an advantage with the E-MTB. A section leads past a ledge. There are a lot of loose rocks here. A bit crisp for driving in steep terrain. The final section, just before the White Wall, is the steepest. You work up a sweat. If you drive in the opposite direction, you are on a groovy trail, which, however, requires high concentration.
