Description of the walk

The start and finish are on the tarmac road leading to the Val d'Aren quarry. It is best to park about a hundred metres after the bridge on the left at an intersection so as not to obstruct the passage of lorries during the week.

(S/E) Join theGR®®51, which follows a shaded path on the left bank of the Aren. Follow the well-markedGR®® (red and white markings) gradually climbing up to the Gros Cerveau ridge. After a few hundred metres, you will reach a three-way junction (cairn).

(1) Follow theGR®® which continues to the right (south). You will reach a disused military fort, the Ouvrage de la Pointe, which is accessed via a footbridge that is closed.

(2) Follow theGR®® trail along the south side of the fort. Quickly leave the tarmac road and continue along theGR®® trail which runs along the north wall of the fort. Follow the path along the ridge via a beautiful aerial route with a few short steep climbs with carved steps leading to the Pointe du Cerveau.

(3) While following theGR®®, descend the ridge to reach the gap at the edge of the road below (D2220).

(4) Descending the gap, you can visit the Grotte du Garou cave, located about a hundred metres to the north. To reach it, follow the blue markings. After about twenty metres, on the left, climb a 2-metre-high rocky outcrop equipped with rungs. Continue along the blue trail to reach the cave below. Return to theGR®® by following this path in the opposite direction.

(4) Turn left and continue onthe GR®® trail, which crosses the wooded area above the road to the east. Along the trail, information panels mark an educational trail. At a small clearing, the trail passes close to a chasm known as "De la Femme Morte" (Dead Woman's Chasm), which is protected by a gate (sign with FFS description). Continue along the trail, which leads to a large clearing at the intersection of the road and a track.

(5) At this cleared area, after about 30 metres, join theGR®® trail, which winds through the woods above the road. Cross a blue-marked trail that leads down to the Val d'Aren before reaching a water cistern located in a bend in the road below the summit of Gros Cerveau.

(6) Continue straight on theGR®® which winds its way up through the sharp limestone pavement to reach an observation table located at the edge of the cliff. Follow the track for about 50 metres to the fort. Leave the track and follow theGR®® which goes around the Gros Cerveau fortification to the north-east, crossing a ditch via a footbridge. After about 50 metres, a path opens up on the right.

(7) Leave theGR®® to take this path, which climbs diagonally towards the top of the fortifications. Follow the edge of the enclosure towards a telecommunications pylon to the south-east to reach a geodetic marker located on the edge of a large plateau overlooking Toulon.

(8) Continue along the embankment, which extends northwards along a path. After about 50 metres, rejoin theGR®® at the bend marking the start of the descent.

(9) Follow theGR®® trail, which descends rapidly in a series of hairpin bends to the north-east. At the end of the bends, the slope levels out and after 250 metres, a narrow path marked in blue branches off to the left and north. Continue along theGR®® trail and after 100 metres you will reach an intersection (signposted 'Danger Carrière').

(10) Leave theGR®® which continues to the right and take the path on the left to the north-west. After about 100 metres, leave this path and take the narrow path marked in blue, which branches off to the left to the south-west. After a short descent, you will reach a valley at a tree (cairn). The trail veers to the right. Continue downhill, following the path along the right-hand side of the gully. You will come to a large open plateau bordering the quarry, where the trail disappears.

(11) Descend this rugged plateau, shaped by quarry machinery and littered with rocks and shrubs, following the left-hand edge of the quarry. After about 200 metres, you will reach an old track covered with sparse vegetation overlooking the quarry. This track leads to the bottom of the quarry, where large boulders block the way. Do not enter the quarry area, but continue along the path that extends the track, skirting the quarry to the south. Follow this gently sloping path. After about 2 km, you will reach the entrance to the quarry.

(12) Turn left onto a path that climbs diagonally above the road. Follow this path along the cliff edge and, after about 1 km, return to theGR®®51at the start of the climb (cairn).

(1) Continue the descent by taking theGR®®51on the right (north-west) to the car park (S/E).

Notes

The descent runs along the edge of the Val d'Aren quarry without entering the working areas.
This means that there are several signs prohibiting access and warning of danger along the descent between (3 and 5).

The descent from the embankment at the top of the quarry is on very hard siliceous sand, which can be slippery in steep sections. Although the slope is relatively gentle, the rugged terrain requires caution, and walking sticks may be useful for some.

Due to the presence of the quarry, noise pollution is possible during the week (machinery and blasting).

The duration of the route indicated does not take into account visits to the cave and fort.

(9) Alternative route:
It is possible to descend via the Blue trail to reach the bottom of the Talweg directly. This shortcut, which descends a scree slope, is steeper and more technical than the route described.

Worth a visit

The name of this peak, "Gros Cerveau", comes from the Provençal "Gro Cervo", which means "Great Stag", like the legendary creature that lived on this hill in the 18th century.

It is common to encounter Rove goats near the summit.

The two structures were built between 1889 and 1891 to defend the harbour of Toulon in the event of an invasion from the interior of the country via the Gorges d'Ollioules. The main barracks could accommodate 250 men. It is now in ruins, but it is still possible to see the walls of the barracks, an underground shelter that was used as an ammunition store, and the remains of the gun mounts in their circulation gallery.

Outside the fort, in front of the main gate, a German blockhouse from the Second World War is visible.

 Always be cautious and plan ahead when you're outdoors. Visorando and the author of this route cannot be held responsible for any accidents occurring on this route.

The indicated car park is no longer accessible. You can park along the road, a little above the tunnel. The path to Gros Cerveau is very good with superb views. Avoid returning during the week because of the quarry.

The first part of this hike is beautiful, running along the ridge with stunning views across the coast from La Ciotat to Toulon.
However, the descent is difficult to follow (use the GPS track!) and the return along the quarry is long and monotonous. In addition, this trail is poorly maintained, and you have to make your way through branches, some of which are prickly.
The indicated car park is no longer accessible. You can park along the road, a little above the tunnel.

Beautiful hike. The route is very easy to follow when you stick to the GR51, but becomes more difficult once you leave it on the descent above the quarry.
It is impossible to park on the access road to the quarry, so we recommend parking on Chemin de Fontanieu on the other side of the main road, passing under the bridge.

Disappointing route through dusty undergrowth due to the quarry that you walk alongside for 4 km on the way back...
The view from the top of Mont Caume is breathtaking, but it's better to climb up the other side (starting from the Jardin des Oliviers in Bandol)

We drove back along the road next to the summit, which is not open to cars due to the noise and dust caused by the quarry and lorries
Otherwise, it was very pleasant and offered beautiful views of the coastline and the hinterland

Impossible to park at the start: stone blocks had been placed there. The route isn't very well signposted. A shame. But what a magnificent view!!! We couldn't complete the loop... We retraced our steps.

Hello,
The description is very good up to point 9.
From there on, the blue markings are crossed out, meaning that the return route via points 9, 10 and 11 is prohibited by the quarry and dangerous.
I therefore did not take this return route, and local people also told me that the path was dangerous, poorly marked, etc.
I therefore advise against it.
The path to Gros Cerveau is very good with superb views!!!!!!

Hello,
We did this hike today in 5 hours, including a lunch break.
It is no longer possible to park at the indicated starting point, as large concrete blocks have been installed.
To reach the quarry, we had to cross a restricted area. ("quarry restricted area, danger").
Not to mention the somewhat complicated descent to reach the edge of the quarry.
For these reasons, I do not recommend this hike, and instead suggest a round trip to the fort.

A hike with breathtaking views!!!

But you have to earn this pleasure! The hike is rated as moderate, but I would say it is quite difficult with average signage and a very steep and rocky descent from point 8 to point 10. Moreover, the start of this descent is very difficult to find because the sign is not very visible and slightly below the path.

To complete the hike in 4 hours 35 minutes, you need to be a good walker. For an average walker, I would say it takes more like 5 hours 30 minutes

But it's still a great pleasure.

As a bonus, at the top of Gros Cerveau, we encountered three pheasants!

One last point: the last part of the route runs alongside the quarry. We were lucky enough to do the hike on Easter Monday and the quarry was closed. I would recommend doing this hike at the weekend or on a public holiday.

What a treat! Magnificent views, a variety of terrains and the goats of Le Rove.
I grew up not far from here and found myself transported back 35 years.
Thank you!

A beautiful hike, worth doing in its entirety. A few people at the points accessible by car. But 80% of the hike, no one.
The return via the hunters' path is deserted and little used.
Very beautiful views of the entire region.

Hello,

A very beautiful hike with no technical difficulties. The return trip was a bit complicated due to the loss of the trail caused by work at the quarry.

Please note that the embankment mentioned in point 10 is actually a descent into scree. It is not very long, but it is really not easy for an average hiker

Between points 9 and 10, you must telephone the quarry to find out if it is possible to pass (blasting)
Then, after leaving the GR, the route forces us to cross large scree slopes. These rocks are very unstable and the edge of the quarry is close by. We gave up and climbed straight up through the scrub to retrace our steps.
