When you take this extra segment, you will begin from Gfrill, which is located at approx. 1,300 meters above sea-level, and continue to Buchholz at 560 meters above sea-level. At first, you'll have a pleasant, relaxing stroll downhill until you come to Unterstein. You can then continue along the old aerial lift trail until you reach the vestiges of an old cableway. The trail then goes downhill until you come to the brook where the Truden Faultline is especially noticeable. This boundary is distinctly visible not only on the basis of the different geological strata (dolomites and porphyry), but also due to the abrupt change in vegetation. You can then continue to the small village of Buchholz.
