From the Genova-Ventimiglia motorway, turn right and, after about 300 m, turn right again, after passing the hospital you reach Terralba. Here you take Via Pecorara on the left (immediately after a pharmacy) which climbs steeply to the north.
At a crossroads, go uphill to the right, following the signs for “Centro Ornitologico - case Vaccà” up to Pian del Curlo where you can leave your car.
From here, take the uphill cart track, pass Case Vacca and continue on the path to the right (way marker two red stamps); it reaches the horizontal path (way marker A red). In 10 minutes, when you reach the top of the ridge, you can see the refuge and the climbing area with the sea underneath.
Beyond the Scarpeggin, the track follows the head of a wide valley, then you leave on the left the track directed to Passo della Gavetta (way marker V), to continue on path A. Passing under the high voltage pylon, you reach a small ridge, where the start of the route is located near a rocky pillar, indicated by a large stone marker on the right and a bolt on the plate on the left (h 1.15 from Curlo).
Almost all the shots can be safely taken in preserves, given the relative ease of passing.
Follow the path marked “●●” to the clearly visible Passo della Gavetta (0.15 h from the top). Following the path marked with the "V" to the left, you return to the path "A" and, through the alpine refuge Scarpeggìn, back to Agueta (0.40 h from the pass).
