The "ABS" at the Karlspitze peak is quite the tour! Few others can match it in terms of views and variety. Just so you know, the initials ABS do not stand for anti-lock braking system, but for the initials of the first climbers. Braking would be no help at all in mastering the route’s eleven pitches (at most in two short passages). The course designed by Andy Schonner and Bernhard Salvenmoser skilfully guides climbers from slabs into cracks and finally into an insanely angular chimney in which full-throttle laybacks are needed to reach the finish. Climbers will need to be up to the challenge. The protection is good but still sometimes tricky and the rappelling back down via route is not exactly beginner-friendly. But if you keep all this in mind, you will surely have fun at the Gaudeamuspfeiler!
