Even if you're physically fit, walking up steep slopes is hard work. Jump aboard Schraegbahn Funicular and ascend the mountain comfortably and quickly. The views are nicer too!
Situated in Lasa, this incline railway is worth a visit. But you'll find tons more to see in the area. Golfclub Val Venosta, and Churburg Castle aren't too far from Schraegbahn Funicular.
