The San Boldo Pass, located between the provinces of Treviso and Belluno, is a road engineering masterpiece unique in the world. Known as the "Road of the Hundred Days", it was built in record time by the Austro-Hungarian army in 1918 for wartime needs. Its peculiarity lies in the final meters of ascent, where the roadway winds through five tunnels carved into the living rock, connected by very tight hairpin bends that seem to overlap vertically. Traffic in the tunnels is regulated by a single traffic light, as the road is so narrow that it only allows one vehicle at a time.

A challenging climb with many sections in double digits. The asphalt is in good condition, making the descent easier.
