The start is at the bottom of the North West arête of the Mt. Pellegrino, in Palermo, some dozens of meters from the parking spot of the Falesia dei Valdesi. From the parking spot get on foot toward the North West arête, up to the Bunker. The route starts on the left of that Bunker, near the inscription "Spigolo Valdesi". You can see the first pitons from the bottom.
The climb down is by abseil. Once at the end of the route (on the top of Mt. Pellegrino) traverse to the right. After some meters, you find the first of three abseil points. These three abseil points are 25 meters from each other. Usually the third (last abseil) is joined with the second. Anyway, please remember that the third abseil point is a bit hidden, under a small roof.
