It is in northern Umbria and lies between Gubbio and Cagli at 632 meters.

It opens up as a natural plateau near the border with the territory of the municipality of Cantiano, in the province of Pesaro and Urbino.

Although it is on the border between Umbria and Marche, it does not represent a watershed between the Adriatic and Tyrrhenian sides: in fact, it connects the Burano valley (Metauro basin) to the Sentino valley (Esino basin).

Coming from the direction of Rome, after Scheggia there is a gentle climb up to the pass proper, beyond which the road descends rapidly towards the border with Marche with a few bends until it reaches a barrel bridge built entirely of stone during the 19th century.

[1] An Umbrian and then Roman temple dedicated to Jupiter Apenninus once stood there,[2] as is also suggested by some Roman baths found nearby.
