Monte San Petru as seen 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

Car park located at the Col de Saint-Eustache, on either side of the RD420 which links Petreto-Bicchisano to Aullène, near the ‘Chez José’ chalet and refreshment bar.

(S/E) Start of the walk from the RD420: head west along the wide track, leaving the chalet behind you.
When you reach the water tank, leave the descending track and follow the ascending track opposite (signpost visible).

(1) Soon after, at the Fork in the road, take the path that climbs to the right, ignoring the track that branches off to the left (closed off). You will then reach a shaded woodland area and follow a path climbing at a steady, gentle gradient. Yellow markings are present throughout the route.

(2) A path branches off to the left. Ignore it and continue straight on towards the woodland.

(3) At a Y-junction, in a left-hand bend, ignore the path on the right – where a signpost indicates the descent to Petreto – and continue along the track opposite towards the Col de Velica (signposted), leaving the wooded area behind you.

(4) At Col de Velica, ignore the path leading down to the left and continue straight ahead, following the track which now climbs up onto the ridge (signpost to San Petru). If you look back regularly during the ascent (or on the way back), you can see the Aiguilles de Bavella and Mont Incudine. The path climbs gradually in stages until it reaches San Petru, which overlooks the path on the right.

(5) At San Petru, for those who wish, a short, easy climb leads to the summit, offering a panoramic view of the Taravo valley to the north, Propriano Bay to the south-west and Mount Cagna due south.
For the return journey, follow the same route as on the way up.

(4) On the way back, at the Col de Velica, ignore the track branching off to the left (the ascent route) and take the path sloping gently down to the right, starting with a grassy section (signpost – towards Col de Saint Eustache). Follow this route down, which offers fine views of the surrounding mountains.

(6) At the T-junction just after the bend to the right, leave the main track (closed off) which is blocked by tree trunks, turn left and follow the path down through the fir trees until you rejoin the path you took earlier.

(2) Turn right onto the path that descends and leads back to the car park at the start (S/E).

Thank you for suggesting this walk – it’s simply splendid and presents no particular difficulty for this type of mountainous terrain. It’s best to follow the circular route in the direction indicated: the ascent is steady but fairly gentle, and as it’s on the north-facing slope, the temperature is very bearable in summer if you set off around 9 am. The round trip to Mont San Petru is superb! And the descent is a little steeper, but quite quick. Do consider taking walking poles to take the strain off your knees if needed. There are several well-designed information boards, and it’s also a place for contemplation. We came across very few people on 22 August 2026. We did the walk the day after some heavy thunderstorms, with no particular difficulties. The view is spectacular.

Stunning views once you reach the summit at 1,400 metres. Best done as early as possible in the morning to avoid the heat. Beautiful scenery.

A fairly easy walk with lovely views from Mont St Petru. Another highlight of the walk: carry on straight ahead, following the small aluminium signs pointing to the memorial; it takes about 15 minutes. The memorial is a small chapel built to commemorate a DC9 plane crash in 1981, in which 180 people died. Return via the same path.

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.
