The fourth stage requires a great deal of physical fitness and endurance, even for experienced mountain hikers. On the ascent and descent, a few meters of altitude must be mastered. From Tanas, the Venosta Valley High Mountain Trail leads to the Rimpfhöfe farms above Alliz/Allitz, and from there via the Monte Sole mountain above Silandro/Schlanders to the Schlandrauntal Valley and then to the Schlandersberg mountain. Along Monte Sole mountain, the route leads past dilapidated mountain farms. The Zuckbichl and Laggar farm ruins were forced to cease operation due to the scarcity of water at Monte Sole in Venosta Valley. The route leads past the mountain farms of Forra and Hofschank Egg farm bar (refreshment stop) until reaching S. Martino in Monte. This small mountain village above Laces/Latsch with 120 inhabitants is home to rustic mountain farms and the pilgrimage church “Zum Heiligen Martin” and is one of the most beautiful destinations in South Tyrol. The cable car at S. Martino in Monte is open year-round and runs daily from Laces to St. Martino.
