Monte San Petru from the Col de Saint-Eustache.

At the gateway to Alta Rocca, this moderately difficult hike allows you to enjoy the exquisite scents of the maquis in spring. The route begins with a pleasant woodland trail before reaching the ridge, which offers views of the Taravo valley and the Rizzanèze valley. From San Petru, there is a magnificent panoramic view of the Gulf of Valinco (Propriano) as far as the Gulf of Ajaccio. On the way back, the descent is opposite the Aiguilles de Bavella.

Description of the walk

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).

Superb hike, 11 degrees at the pass, wind and fog, but that cleared up by the time we reached the summit, where the sun was waiting for us. The climb up the right-hand path is very pleasant, dotted with little information boards. Reaching the summit rewarded us for our efforts and we enjoyed our snack with a view. I recommend taking the same path down as you took up, as the other path is not very pleasant in my opinion.
Note: On the first Sunday in July, a religious ceremony is held at the memorial to the plane crash. It can be very crowded on that day.

A perfect walk with magnificent views. Two hours of steady, gentle climbing, an hour and a half for the return trip – we are very occasional hikers.
The yellow markings are very easy to follow, no problems whatsoever, just pure enjoyment.
Definitely worth doing. Thank you to the designer.

Hello. A very beautiful walk with magnificent scenery. The first part is a little shady, but the entire climb up Mount Petru is open. So it's best to do it early in the morning during the summer to get the most out of it without suffering from the heat and to enjoy the peace and quiet.

Done in September after the big heat, starting from the pass at 16 degrees, arriving at the top at 8 degrees max and a strong wind... distance covered 9.33km in 3h15 with picnic. We're occasional hikers.
Magnificent circuit with no difficulties. Explanations on signs all along the route. Just be careful on the way down when you branch off from the way up, the path to take to the right is 100m before the visorando trail.
I recommend this route to discover the beauty of Corsica from above.

What a pleasure this hike was, one of the most enjoyable we enjoyed during our stay. The views are magnificent, from the Aiguilles de Bavella to the gulfs of Ajaccio and Valinco, the vegetation is varied, the rocks form beautiful natural sculptures, and there are interesting little explanatory panels along the way. The site of the DC9 crash memorial is very moving. On the way back, don't hesitate to do the loop, which adds 15 minutes (turn left at point 4 on the way down) but is shadier. And of course, don't forget to stop at José's for a drink on the way back.

The weather conditions were special, as we climbed into the clouds that swept over the path.
Our view of the distance was therefore limited. And we didn't suffer from the heat
However, the path is very beautiful.
Easy walk. Lots of signs along the way. Well done to the volunteer who made the signs!

The walk was very well signposted. There is no shade on the ridges, so be careful if you go in the heat. We were there in April and fortunately we had a little wool. We loved the view and the maquis on the mountain ridges!
In terms of difficulty, the last 20 minutes before reaching the summit are a little more technical with rocks but largely accessible even for amateurs.
It was so beautiful!
Ps: doggy friendly hike

A very nice walk. Depending on the weather (it was hot on 22 August), the first part could be done under cover on the way back. The landscape is open and there are many animal-shaped rocks - leave it to your imagination ... the site is remarkable, with a view from the summit that is not to be missed.
On the way back, we met José, a dream-maker he says... we believe him, we spent an hour talking about everything, life, nature... and Corsica. Don't leave without meeting him in his chalet.

It's a lovely walk, and well done to the volunteers we met for maintaining the paths and the small, hand-made signs, as well as the beautiful reconstruction of the Petreto Bicchisano chapel in tribute to the victims of the crash, which you can see once you reach the summit.
Beautiful panoramic views from the top.
If the weather is poor, remember to bring warm clothing.

The most beautiful hike of my 15 days in Corsica.
A must-do for the views over the bays of Ajaccio and Propriano!
And a really warm meeting with the owner of the Café du Col de St Eustache. Thank you for this moment

Lovely walk with a beautiful viewpoint at the finish. The first part is in the shade in the woods. On the way back, depending on how hot it is, taking this path (on the left) may be a better option.
After the walk, a stop at José's is a wonderful reward. His authentic charcuterie and cheese are magnificent.
Thanks to him, after a few bad experiences, he has reconciled us with the Corsicans.
