Access by car:
From the RT 20 in Francardu, take the direction of Pont de Castirla via the D84. After the bridge, turn right and follow the road up to Col d'Arbitro and its white oratory at an altitude of 664 m.
Once parked, you will be able to see higher up the chapel that you will join. Take the track to the North and follow it leaving the left and its orange marks. Continue to a clear plateau which is also the crossroads of several tracks. Take the one on the left (west), to quickly reach the chapel nestled in the thicket.
Then return on your steps to the plateau, and head south. After 10 to 15 minutes walking downhill, you'll find the paved road that leads to Castiglione. Then turn left to the vehicle while walking on the right side of the road.
You will arrive at a sheep park and it will be possible to take the cemetery road on the right to see the San Nicolao chapel, and thus lengthen the journey somewhat.
