The San Boldo Pass, which connects Valbelluna to Valmareno between the municipalities of Cison di Valmarino and Borgo Valbelluna, is one of the most spectacular passes in the Venetian Prealps. Known as the "Road of 100 Days", it was built in record time in 1918 by Austro-Hungarian military engineers for logistical purposes during the Great War. Its architectural uniqueness lies in the five hairpin bends carved entirely into the rock and regulated by traffic lights, which overcome a very steep difference in altitude in a small space.

It's an exceptional gateway to the Dolomites, with calm, crystal-clear waters nestled between the mountains. A wonderful place with hardly any traffic.
