The Passo di San Boldo, also known as the "100-Day Road," is one of the hidden gems of the Belluno and Treviso Prealps. This mountain road, connecting the foothills of Treviso to the Valbelluna valley, is a true monument to history and human ingenuity. Its fame is linked to the speed with which it was built during the First World War: in just 100 days, the Austro-Hungarian army, with the help of prisoners and local people, dug five tunnels through the rock, creating an unprecedented engineering feat. Today, the Passo di San Boldo is much more than just a road.
It is a suggestive place rich in history, where you can breathe a unique atmosphere. The tunnels, carved into the living rock, allow you to immerse yourself in a distant past. But the Passo di San Boldo is not just history. It is also an ideal place for nature lovers, with its breathtaking views of the Dolomites and the surrounding mountains. And for those seeking a little relaxation, there are numerous farmhouses, refuges, and trattorias where you can taste local products. Driving it has its charm, but by motorcycle it becomes one of the most beautiful roads to travel.
The most trained and daring can ride it by bike, in the footsteps of the legendary Jacques Anquetil who, during the 1966 Giro d'Italia, devoured it, followed closely by the Pink Jersey of a very young Gianni Motta. Almost 6 km for 451 m of elevation gain with an average gradient of 7.5% make this road one of the most challenging in the Prealps.
