Circular Sainte-Victoire and bottom of Lake Bimont

An exceptional walk at the far end of Lac du Bimont, to be done before the dam is filled in 2019. Views of the most beautiful side of Sainte-Victoire, a lovely climb, a magnificent panorama of the region, a walk at the far end of the lake, and old stones bearing witness to times gone by.
Important: The final section of this route – part of which is marked on the map as being in the lake – was accessible until May 2019, before the lake was filled. Please read the practical information below.

11/09/2024: The Imoucha path will be closed for three months, from 1 October to 31 December (2024 and 2025). The walk cannot be undertaken during these periods. See practical information.

Description of the walk

Park in the upper Aurigon car park, leaving the first car park on your right.

(S/E) Walk to the end of the car park and pass the two retractable bollards that prevent vehicles from passing. Cross the concrete bridge, then take the small wooden footbridge on the right to cross the large meadow heading north-east. Enjoy the view of Montagne Sainte-Victoire. Reach the end of the meadow and cross the bridge.

(1) Take the track on the right, which leads uphill and is marked with green lines and theGR®® 653A sign: this junction is also on the return route.
Head up the track. At the hairpin bend to the right, carry straight on along the path heading east. This is a shortcut that rejoins the track a little further on.

(2) Continue eastwards along the track, which takes you near the hamlet of Le Trou and the Cézanne Refuge. Leave them on your right and head north.

(3) Leave the track and take the path that winds between the low walls of old terraces. As you cross the ridge, look out for the rock known as ‘Le Baiser’. Follow the path climbing up through the rocks known as ‘Pas du Dinosaure’. You’ll reach a junction of paths.

(4) (546m) Turn right onto the path marked “Difficult” and marked with red lines. You’ll soon reach the “Pas du Berger”. This is a fairly vertical slab about 5m high, which you climb first to the left and then to the right (good handholds on the right). Afterwards, the path is steep; it veers to the right after a ledge, then to the left across slabs. Follow the markings carefully to the “Pas du Moine”, where you’ll reach the Imoucha path.

(5) (767m) Here you’ll discover the north-facing slope of the mountain. Head for the rock face above you. Instead of following the blue markings, turn left, heading due east, and walk along the base of the rock face, then up its upper section, until you rejoin the white-and-red marked path – this is theGR®® 9, the Chemin des Venturiers.

(6) Follow this path downwards; it becomes a rescue track. The descent is steep until you reach a hairpin bend to the right.

(7) (370 m) Take the unmarked path on the left, leaving theGR®®9here; it climbs slightly at first, through the woodland. The path then descends, runs along the edge of a field and follows the river known as the Cause. Follow the river and cross it twice. You are now following a track on the left bank. Leave this track by veering northwards to enter the area cleared when the lake was drained.

(8) Cross the ruined bridge. Continue across the centre of the empty lake to reach the gorges.

(9) The landscape opens out onto a vast expanse overlooked by the dam. Two posts have remained there since the reservoir was filled. Pass close to the metal post and continue south-west. Head back up towards the bank, as if you stay at the bottom all the way to the dam, you will be unable to climb back up due to unstable cliffs.

(10) Follow the edge of the vegetation southwards and head back down into the dry valley as soon as possible. Make your way back up the valley floor. At the edge of the vegetation, take the unmarked path leading uphill.

(11) Cross the Sentier Imoucha (351m) and continue climbing south-southeast. You are now in the Vallon de la Dispute.
You’ll come to a fairly level track. Turn right, heading due west. Five minutes later, the track descends.

(12) Turn left and take a track that descends; you will see a few green markers and the signposts forthe GR®® 653A. When you reach the bottom of a concrete track, you are in a former shooting range, the eastern part of which is sometimes off-limits (275m). Cross it heading south, taking the path which is slightly to the left of the previous track’s centre line. Follow the stream back to the original junction.

(1) Go round the meadow on the left, following the stream along a path, to reach the car park. (S/E).

Notes

The Imoucha Path is closed; further information here.

Please note: There is no path at the far end of the lake as the area has been submerged for 60 years. In the event of recent rainfall, there is a risk of getting stuck in the mud. Do not set off alone.

Please note! Between1 June and 30 September, access to the forest areas is restricted by prefectural order. Please check the official website.

Please note: The Prieuré de Sainte-Victoire has reopened, but access is restricted; please see this page for further information.

  • No water sources, no shelter.
  • Sturdy footwear suitable for rocky terrain, and sun protection.
  • Climbing the Pas du Berger may pose a challenge for some people, who will need to be belayed.
  • Be prepared to cross the river: in certain conditions, you will need to wade through the water between (8) and (10).
  • After (7), if the water level in the lake prevents you from continuing the walk, there is an alternative route: head north to the Departmental Road 10 at its junction with theGR®® 9, take bus 140 (Cabassol stop) towards Aix, where you’ll then take bus 110 towards Puyloubier. Stop at the Aurigon car park in Roques-Hautes. Alternatively, if the Bimont dam is open – that is, on Saturdays and Sundays whilst works are ongoing until 2019 – you can take the D10 then the D10f, cross the dam and reach (12).
  • To avoid the lake, you can choose to reach the starting point via the Sentier Imoucha. From (5), turn left and head to (11) by following the blue signposts.

Do not use the definite article ‘la’ before Sainte-Victoire: say ‘A walk to Sainte-Victoire’ or ‘A walk to Montagne Sainte-Victoire’.

Worth a visit

  • The pier ofthe Roman aqueduct at the entrance to the car park.
  • (1) Site of a resurgence; in dry weather, it is fed by Lac du Bimont, provided the lake is full.
  • (3) The hamlet of Le Trou, now in ruins except for the Cézanne Refuge, which is locked. If you have time, visit this hamlet: the vault of a chapel, a threshing floor, a well, building remains, and a viewpoint. You can walk a circular route via the metal staircases.
  • Between (3) and (4), look out for the rock known as‘Le Baiser’, where you can make out a couple kissing when viewed from above, about a hundred metres away. The woman is on the left, with her arm around the man’s neck.
  • (5) The Mur du Pré des Moines has been restored. An information plaque is affixed to the western end of the wall.
  • (5) From this point, you can take a detour via the Priory (the Imoucha path, marked in blue) and the Croix de Provence (marked in red and white), then head back down via the Priory and the red-and-white-marked path to (6). Allow an extra hour to enjoy the scenery a little. Please note: you should check this website to see if the Priory is open.
  • Between (8) and (10), you may come across freshwater mussels.
  • Between (10) and (12), at an altitude of 351m, you can follow the Imoucha Trail to reach the Bimont Dam. If it is open (only at weekends until 2019), you can cross it to reach a fountain, just before the Bimont car park. Allow an extra 40 minutes. On the right bank (north), just after the dam, there is also an orientation table and information boards about the Canal de Provence and the dam.

Due to rising water levels, it is no longer possible to complete this hike in its entirety.
Please read my previous message!

We didn't complete the entire hike because Lake Bimont was starting to be refilled with water.

As expected, the water level is rising. To see what can still be done at the bottom of the lake, do the route in reverse. Once you reach the point (10), you will see if you can enter the gorges. If not, bear in mind that this hike will not be possible again for many years.

Please note that the dam is flooded at this time (26/05/2019).
so we took the Imoucha trail instead.
The walk was much shorter, but in the end, considering the weather, it wasn't so bad!

That's right, ferdial34, the water is rising, and I don't know if it will go down again before they refill the reservoir.
Will this hike, as I've described it, still be possible?

I didn't do the hike as described, but I went down behind the dam. There is currently a lot of water and I doubt that the hike is possible.

At this time of year, given the rising water levels, if the aim is to see the bottom of the lake, it is prudent to do the circular route in reverse. That way, if it is impossible to cross due to the water level, you can get back to Roques Hautes more quickly.
But it's a shame to miss out on the beautiful climb from Pas du Berger to Pas du Moine. And the climb via Les Venturiers is unrewarding, in my opinion. That's why I chose to go anti-clockwise.

I discovered the description after doing it on my own, setting off at midday
Rand'eau les pieds dans l'eau is something to do again and again before it's too late.
Personally, I set off from the Venturiers car park via the Cabassols single track, which gives you plenty of time to enjoy the surreal landscape of the lake at the start of the hike.
After the November rains, the lake was a little flooded and you have to search a bit to get out while staying as close to the lake as possible.
Return via Imoucha and Les Venturiers after a detour via the priory.

Do not go on this hike alone because of the risk of sinking into the mud.
A rare temporary hike, with an expiry date fast approaching: the lake will fill up again after the Bimont dam is repaired. That's why you had to make the most of it!
We did the hike between two days of rain, at full speed in one afternoon! There was a fairly strong south-easterly wind at the Pas du Moine pass (where the view is beautiful), which weakened afterwards, sheltered by the wall and on the descent.
After the small bridge at the start of the lake, with the rains of the last few weeks, it was very, very muddy.
I'm only giving a good rating for the description, because in the lake you have to make your own trail: you have to follow the stream, avoiding getting stuck.
It's very interesting to walk through the gorges that have been submerged for sixty years. You can find shells on the ground.
At the broken pylon, keep to the left if you see that it's muddy, otherwise you'll get stuck.
To climb out of the lake, there is no trail, so you have to choose the best route, follow the old edge, pass by an old island, and descend into the valley where walkers have trampled the grass.

Everything is fine until you reach the lake. Contrary to what is indicated, there is no path in the lake.
You either end up in the mud or in tall grass.

(!) Covering clothing is essential! Long sleeves and long trousers: this autumn, tall grasses (knotweed) have grown at the bottom of the lake. They reach chest height after point 8 and sometimes exceed 1.80 m. In the gorges (before point 9), you must either walk along the edge of the riverbed through these grasses or walk in the riverbed itself, under the grasses that form a tunnel. It is better to be warned...
