The area is located between the towns of Isili and Nurallao, on the south end of the lake. Driving from Isili you'll spot the crags on your right-hand side. Take a sharp right turn before the bridge, and go down to the level of the water, following the dirt road until it goes over a little bridge. Park on the side of the road allowing space for other cars.
Corvo Spaziale
At this point enter the gate (and close it after you) and follow the path at the base of all the crags. After only 50 metres there'll be another path diversion to the left, where Corvo Spaziale is located
