Parking is available at the Col de Saint-Eustache, on either side of the RD420 road linking Petreto-Bicchisano to Aullène, next to the "Chez José" chalet and refreshment bar.
(S/E) Start of the hike from the RD420: head west on the wide track, leaving the chalet behind you.
At the cistern, leave the descending track and follow the ascending track opposite (signpost visible).
(1) Quickly, at the fork, take the path that climbs to the right, ignoring the track that branches off to the left (closed). You will then reach a shady woodland and take a path that climbs gently and steadily. There are yellow markings all along the route.
(2) A trail branches off to the left. Ignore it and continue straight ahead towards the undergrowth.
(3) At a Y-junction, in a left-hand bend, ignore the path on the right, which has a signpost indicating the descent to Petreto, and continue on the track opposite towards the Col de Velica (signpost), leaving the wooded area behind you.
(4) At the Col de Velica, ignore the path descending to the left and continue straight ahead, following the trail that now climbs up to the ridge (signpost for San Petru). Turning around regularly during the climb (or on the way back), you can see the Aiguilles de Bavella and Mont Incudine. The trail climbs gradually in steps until it reaches San Petru, which overlooks the path on the right.
(5) At San Petru, if you wish, an easy, short climb will take you to the peak, offering a panoramic view of the Taravo valley to the north, the bay of Propriano to the south-west and the Cagna mountain directly south.
To return, take the same route as on the way up.
(4) On the way back, at the Velica pass, ignore the track that branches off to the left (the path you took on the way up) and take the path that descends gently to the right, starting with a grassy section (signpost for Col de Saint Eustache). Follow this route downhill, enjoying beautiful views of the surrounding mountains.
(6) At the T-junction at the end of the bend on the right, leave the main track (which is blocked by tree trunks), turn left and follow the path downhill between the fir trees until you rejoin the path you took earlier.
(2) Turn right onto the path that descends and rejoins the car park at the start (S/E).
