The Calà del Sasso is a path leading down from the village of Sasso di Asiago towards the town of Valstagna, province of Vicenza, north-eastern Italy.

It has 4444 steps, is 2.546 km long, and is the longest staircase in Italy[1] as well as the world's longest staircase open to the public[2] (the service stairway for Niesen Funicular is longer, but only open to the public once a year).

The highest and lowest points on the path differ by 744 m. Next to the staircase runs a gully.

The gully was used to transport timber from Sasso downhill.

Once in Valstagna, Calà del Sasso ends near the river Brenta, where the logs were floated to Venice; here, in the times of the Republic of Venice, they were used in the local arsenal for the construction of boats.
