Calà del Sasso, Hiking trail in Valbrenta, Italy
Calà del Sasso is a historic stone stairway in the heart of Valbrenta, extending seven kilometers between Sasso di Asiago and Valstagna and passing through steep rock faces and forest sections. The limestone steps run alongside a continuous channel that collects and diverts rainwater, while the route crosses small meadows and dense stretches of trees.
The stairway was built in the late 14th century to create a toll-free link between the high plateau and the valley for timber transport. Over the centuries, the path also served as a pilgrimage route and a military access point during the conflicts of the 20th century.
The name Calà comes from the local dialect and means to descend or go down, referring to the direction timber carriers traveled when bringing wood to the valley. Visitors today hike in both directions, though many prefer the ascent to gradually reveal views over the Valsugana valley and surrounding peaks.
The ascent begins in Valstagna at 221 meters and ends in Sasso di Asiago at 965 meters, with the 744-meter elevation gain spread over many short sections. The steps become slippery after rain, so sturdy footwear with good grip is advisable, especially during wet conditions in spring and autumn.
The route contains 4,444 steps, making it the longest public staircase in Italy. The number of steps was chosen to be easy to remember and also carry a symbolic meaning for the communities above and below.
