The fourth stage requires considerable fitness and endurance, even for experienced mountain hikers. There are significant elevation changes to overcome, both uphill and downhill. From Tanas, the Venosta Valley High Mountain Trail leads to the Rimpfhöfe farms above Alliz/Allitz, then continues across Monte Sole above Silandro/Schlanders to the Schlandrauntal Valley and onwards towards Tappein. Along Monte Sole, the route crosses a 70-metre-long suspension bridge and passes 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, the Hofschank establishments Egghof 1677 and Af' Egg 35 (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.
