The Mortirolo Pass, which links the province of Sondrio with the province of Brescia, may “only” be 1.852 m above sea level, but it is one of the hardest, most challenging passes in the Alps. From the valley floor, you can reach Mortirolo Pass from various access routes:
from Mazzo di Valtellina: 12 km of climb with 1300 m of elevation change;
from Tiolo (in Grosio) with a climb of 14 km and 1100 m of elevation change;
from Tovo Sant'Agata with a climb of 12.5 km and more than 1300 m of elevation change
Like other passes in Valtellina, Mortirolo has repeatedly starred in the Giro d’Italia.
