The ascent from the east can be very tricky in spring, as there may still be snow in exposed places.

Magnificent panoramic point Highest peak of the so-called "Güggisgrat", which extends south of the Justistal over the Niederhorn to the Gemmenalphorn. Legend has it that this peak represents the ruins of a destroyed castle. The rocky outcrops that dominate the Justistal west of the peak give the impression of collapsed quarry stone walls. The peak is easy to reach thanks to the railway and the comfortable path.
