Preda Rossa

Preda Rossa is a high mountain pass at an elevation of 1.955m (6,414ft) above the sea level, located in the Province of Sondrio in the Italian region Lombardy. In 1991 the road was severely destroyed by a major landslide and then a bad gravel road on the other side of the valley served as the only way to go up.

But in 2012 the road to the summit was mostly asphalted. There’s only a short gravel section (around 300m). The road is pretty steep, with sections up to 14.0%. Starting from Masino, the ascent is 24 km long. Over this distance, the elevation gain is 1.675 meters. The average percentage is 7 %.
