Forcella di Mastaun in val Senales
Very long and very challenging route, dedicated to trained and technical bikers, who also like to carry their bikes on their backs for a long time. Superb and wild high mountain views.
Go up the Val Senales road to Madonna di Senales, to avoid the tunnels pass carefully on the old road (with prohibition). Or drive up and arrange for car retrieval at the end of the tour.
From Madonna climb to the Mastaunalm (last refreshment stop) with steep sections and then follow the trail to the Mastaun pass 2920 m with a very long and strenuous bike backpacking section. Beware that the snow has already melted. Descent to Silandro valley technical and challenging with small walking sections but very beautiful. From the valley another path on the left smoother and then down the valley on forestry, only at the end still by path. From Silandro go to the bike path and back to the start, or return by train.
