From the D59 linking Sotta to Levie, take the road leading to the village of Borivoli. Drive through the village, heading towards the Col de Colombanu. Park in the dirt car park at the pass.
(S/E) Take the path at the far end of the car park, heading towards Bergerie de Bitalza and Funtanedda. Following the yellow markings, begin a fairly steep climb and, after a few hundred metres, reach an orientation table.
(1) Continue first along a gentle slope before the path becomes much steeper over occasionally uneven terrain, eventually reaching Bocca di Puzza.
(2) Continue to the left to begin a series of hairpin bends and join a track suitable for vehicles.
(3) Cross it and, a few metres further on, rejoin it. Cross this track again to take the yellow-marked path opposite. Continue on and, via an easier climb, reach a crossroads.
(4) Take the wide, flat and pleasant path opposite. Pass by a gate to enter the grounds of the Bergeries de Bitalza.
(5) Walk around this small plateau, passing the Statue of Our Lady of the Assumption and the houses of this picturesque old village. Stay on the yellow-marked path. You will reach a wider track near a cistern.
(6) Turn right onto this track, then return to the crossroads you passed earlier.
(4) Head straight ahead and continue downhill. After a very wide hairpin bend to the left, you’ll reach a junction marked by two cairns.
(7) Continue along the path on the right, down a long, often rough descent through the forest, sometimes obstructed by vegetation, until you reach the Col de Bucagaraccia.
(8) Continue the descent until you reach the hamlet of Vacca.
(9) Turn left onto the road, follow it and you will reach the Col de Colombanu car park (S/E).
