The Scala (staircase) di Giocca indicates the stretch of the old access to Sassari from the route SS131 " Carlo Felice ". Scala in Sardinian language also assumes the meaning of a steep and difficult access road, while Giocca means snail, probably referring to the slow and tortuous turns imposed by the climb).
The 3 km long road climbs from 132 to 312 m above sea level on six narrow hairpin bends obtained along a large edge dominated by sheer limestone walls, so that it was called "the little Moncenisio".
The climb was even more demanding in the past, when it was the only access route to Sassari and the road was stony: arriving from the Logudoro subregion with their loaded wagons, the peasants had to unload half of it at the beginning; then, after having deposited the other half on top, they had to go down again and repeat the operation.
Today its winding curves are the fun of motorcyclists and (downhill) cyclists; moreover, in June there is the "Scala di Giocca - Osilo", the oldest car race in Sardinia: vintage cars and motorbikes start from Sassari and the Scala di Giocca, touch various villages in the surrounding area, including Osilo, before returning to Sassari for the award ceremony.
