Description of the walk

Access: From Malaucène, reach the village of Beaumont-du-Ventoux via the D153 departmental road.
Cross the village and continue to the hamlet of Les Valettes. Park in the small car park behind the wash house on the right at the entrance to the hamlet.

(S/E) From the car park, walk past the hamlet's wash house. The hiking signpost is opposite it.
Turn right towards Plan de Vau,GR®4, walking along the D153 departmental road.
After 250 metres, climb the stairs on the left that lead to the Chapel of the Holy Sepulchre.
Then return to the road and, after about 100 metres, turn left onto the slightly uphill track at the houses on the outskirts of the hamlet.

(1) At the fork after 100 metres, continue left on the track. There are no markings. Follow the track uphill alongside the orchards.

(2) At the next fork, continue to the right. Walk alongside more orchards. The track becomes a little grassy but is clearly marked. Ignore any other tracks and continue straight ahead. The track heads east, continue to the end until you reach a fence.

(3) Cross the fence and take the path veering slightly to the left. There are no markings. The path climbs steadily over stony ground. It alternates between small scree slopes and undergrowth as it crosses the Combe d'Arnoux.
After about 1.2km, the path curves sharply to the left and climbs up a scree slope to reach the Col d'Arnoux.

(4) At Col d'Arnoux, marked by a small plateau, take the path on the right. The trail then climbs through a gravelly and stony passage. The slope becomes steeper towards the end. There are no markings.

(5) You will arrive at a grassy plateau with a cairn. Turn left towards the east on the ridge line. Follow the ridge through the boxwood trees. The well-marked trail continues, alternating between wooded areas and open spaces offering wide views of the north of Mont Ventoux. The path climbs very slightly. Reach the Sommet de la Plate marked by a large cairn.

(6) Continue along the visible path on the ridge towards the east. The path descends and then climbs steeply for about a hundred metres to reach the Pic du Comte.

(7) At Pic du Comte, the path branches off to the north-east and then descends fairly quickly along the ridge at the edge of the woods.
As you approach a reforested area of tall pine trees with bare lower trunks, the path makes a sharp right turn and then continues along the slope through the pine trees towards the south. The forest track is visible below on the left.
Continue for about 600 metres. You will come out onto the forest track, then continue straight ahead on it for about 75 metres.

(8) You will reach the Col du Comte at the large crossroads. Pass to the left of fire hydrant no. 225.
At the hiking post, turn left towards Mont Serein via theGR®4. White/red markings.

(9) After 1.8 km, cross a forest track. At the signpost, continue on the second track on the left leading into the woods, towards Pra Long. Stay on theGR®4. White/red and yellow markings.

(10) After 250 metres at "Pra Long", you will cross the forest track again. Continue straight ahead towards Le Contrat. White/red and yellow markings. After 2.1 kilometres, you will cross a wide track coming from the right. Continue left on theGR®4.

(11) At "Serrières", at the crossroads, take the path on the right towards Le Contrat. Stay on theGR®4. The route follows a wider, stony track.
After about 450m, continue right on theGR®4and walk south for about 500m.

(12) You will come to a small tarmac road. At the "Le Contrat 1" sign, continue left on theGR®4towards Mont Ventoux.
After 200 metres, you will reach the "Le Contrat" sign. Continue left on a beautiful wide track towards Mont Ventoux. TheGR®4andGR®9are now the same.

(13) At the "Combe de la Mine" sign, continue right on theGR®4towards Mont Ventoux.
After a few metres, you will reach the "Les Mélèzes" sign, continuing straight ahead towards Mont Ventoux.
The route initially climbs through the forest, with increasingly tight hairpin bends. It then crosses rocky terrain where vegetation is sparse. Shortly before the summit, pass close to the D974 road at a hairpin bend.

(14) Continue the ascent on the bare ground. TheGR®4then leads to the D974, just below the orientation table.
Cross the road towards the buildings. Pass the "Mont Ventoux" sign. Head up towards the main building of the antenna, passing in front of the souvenir shop to reach the sign marking the summit.

(15) At the summit of Mont Ventoux, head back down the south side, walking along the D974 road to the first bend. From there, continue straight ahead towards the west and descend to the Sainte-Croix Chapel.

(16) At the Sainte-Croix Chapel, take the path on the right that crosses the scree slope while following the road (towards Malaucène). Reach the hairpin bend on the D974 below, then take the wide track on the left towards the radar. There are no markings.

(17) Go behind the radar station, passing to its right. Continue eastwards along the ridge line. Aim for the weather station visible 600 metres away. The path is fairly well marked. There are no signposts.

Once you have passed the weather station, you will arrive at the start of the Rochers de Cachillan. Facing west, the route stays as close as possible to the rocky ridge on the right for most of the way. The route alternates between scree, sharp limestone pavements and a short section through undergrowth. Although there are quite a few cairns, you need to be careful to follow the direction. There are no visible tracks on the sharp limestone pavements (only rock).

After 1.7km through the undergrowth, the path turns right to go around a rocky outcrop. The cairned path then descends fairly quickly into the forest.

(18) Cut across the Tête du Chauva trail at Casseù. At the hiking marker, continue straight ahead eastwards on the trail entering the forest. Then follow the edge of the forest to cross the clearing. There are no markers.
After 450m, ignore the turn-off to the right (blue snowshoe hiking sign). Continue eastwards along the edge of the forest.

You will arrive at a deforested area (ground littered with cut wood and shrub regrowth). At this point, leave the edge of the forest to cross this passage.
At the end of the clearing, enter the undergrowth. You will find a cairned path. Take this path on the left. Continue eastwards for about 650m through the undergrowth on sloping ground.

(19) At the bottom of the descent, at the crossroads, turn right and then immediately left. Follow the mountain bike trail, marked in black. After 350m, you will come to a small clearing.

(20) Head south-west (left then diagonally) on the visible path marked by a few cairns before the undergrowth.
After crossing the trail, the path heads west on downhill terrain via an old access track. Follow the red or green markings on a white background downhill.

(21) At the bottom of the descent, cut across a path and take the one on the right. Yellow markings.
At the fork that appears quickly after 75 metres (not shown on the map), continue to the right along the box trees. Yellow markings.

After 200m, at the fork, continue left. After about ten metres, leave the yellow-marked path and continue left, then turn left again after about 100m.
At a fork below (not shown on the map), continue straight ahead on the wide path. Yellow markings.

(22) At the "Près de Michel" signpost, continue straight ahead towards Col de Comte. Cross the D974 coming from Malaucène, then turn right onto the wide track. Yellow markings.
After travelling about 900m on this wide track, look for a small collapsed cairn on the left. It is located just after the sign marking the entrance to the national forest.

(23) Take the descending path that winds through the box trees. No markings.

(24) At the bottom of the descent (after about 600m), you will come to a wide, rutted track (not shown on the map). Continue along this track to the left, descending.

(25) At the next fork (not shown on the map), continue to the right. After 1.6km, you will come to a small clearing.

(26) Cross it straight ahead and arrive at a track suitable for vehicles. Continue straight ahead on this track for about 600 metres.

(27) Look for a path on the right leading into the undergrowth. Follow the red markings on a white background on the tree trunks. The path descends through a cleared area. After about 100 metres, you will come to another path. Turn right onto this path.

(28) At the Saint-Sidoine Chapel, turn right towards Les Alazards. Take theGR®4(route differs from the map). White/red markings.
After about 1.1km, you will come to a small tarmac road. Continue right on this road to enter the hamlet of Les Alazards. Continue on theGR®4.

(29) At the "Les Alazards" signpost on the D153, turn right towards Plan de Vau via theGR®4. Then, after 250 m, take the uphill track on the left alongside an orchard (track parallel to a wide track on the right leading to private property). Continue along this track uphill until you reach the villa. There are no signposts.

Then continue north (straight ahead) until you reach an uphill paved slanting street. Continue straight ahead until you reach the edge of a fenced olive grove, ignoring the small paths you encounter.
Then walk along the left side of the grove on the grassy path. After a few metres, the path turns north, still running alongside the fence.

(30) At a small grassy fork, continue left downhill and continue on the path that then winds through the undergrowth (facing east). No markings. After about 400 metres, you will come to a path.

(31) Turn right onto this path heading east. After a few metres, ignore the cairn and the path branching off to the left (not visible on the map). Continue eastwards until you reach the fork after 500 metres. There are no markings.

(32) Take the path on the left. There are no markings. At the next fork (after 250 metres), continue right on the path heading east.

(33) After 250m, you will reach a small path branching off to the right. It leads to ancient Roman quarries. Walk there and back.
Then take the path on the right. This follows a paved slanting street downhill (slightly different from the route shown on the map).

(1) At the fork near the houses, descend to the left to reach the D153 road. Follow this road again to the right to reach the hamlet of Les Valettes and the starting point (S/E).

Notes

Water point at the summit (shop/restaurant between May and November).
Uncontrolled water source at the wash houses at the start (S/E) then between (28) and (29) at Les Alazards.

Bring a windbreaker for crossing the ridges.

Crossing part of the north face can be tricky if there is snow or ice in winter.

The crossing of the Rochers de Cachillan requires particular attention, as it is a long passage alternating between scree slopes and deep sharp limestone pavements.

Many sections are not marked.

Two-day trek, no water sources along the route (shop and bar closed at the top of Ventoux).
Day 1: stages 1 to 18 in 7½ hours (lots of photo breaks).
Day 2: stages 18 to the finish in 4 hours.
The climbs are tough on the legs but not technical, and you'll be stopping anyway to admire the beautiful scenery. I didn't meet anyone except at the end of the climb to Ventoux, of course.
There were quite a few hunts over the two days, but I didn't see any hunters and didn't have to make any detours at the start (no grumpy farmers in sight!).
Be aware that there are no water sources along the route (the shop and bar at the top of Ventoux are closed at this time of year) and very few places to pitch a tent. The climb is a protected area (camping is prohibited).
There are small spots after the weather station or at point 18 on a large path next to the antenna (I camped there, 1°C and 80% humidity, so I was glad I had the right equipment!).

A GPS is essential as the trail is not easy to follow at the start of the descent from the mountain and is relatively technical on the rocks (no need to be a mountain guide though!).
For the rest of the descent, you have to make a few small detours because there is a lot of tree felling at this time of year (the loggers were not far away) and piles of wood block the path (easy detours).

A very beautiful trek, the few firebreaks and other vehicle tracks don't last long and the landscape makes us forget these less pleasant passages before we return to pretty trails.

Hello
Taken at the end of October, magical atmosphere, among colourful deciduous trees, leaves on the ground hiding damp roots in places, frosty summit and a good mistral wind ensuring blue skies, pure bliss!
Really lucky to have this magnificent, varied mountain less than an hour from home...

Average trail runner, trainers, poles, shorts, T-shirt, merino wool and Gore-Tex in my bag, VERY useful at the end of the day, gloves would have been useful up there, 2 litres of water over the day (it wouldn't be the same in the middle of summer...) and a plate of pasta eaten while shivering in the Ste Sidoine chapel, which I conveniently came across at 11.30am.
I left Mont Serein at 8:30 a.m. (slept at the campsite, 2 days of hiking/trail running) and arrived at around 5 p.m., between 6 and 6:30 hours of walking, knowing that I made an extra detour to the Tête du Gros Charme but covered the same distance in the end, with 2,100 metres of elevation gain.

I recommend doing the circular in the other direction, whether you start from Mont Serein or Beaumont, as this makes it easier to navigate the technical part of the sharp limestone pavement and gives you more time to look for the few cairns (thank you)
Having already done it downhill, it's steep, slippery in places, doesn't roll easily and is as tiring as going uphill, in my humble opinion!

The rest of the route does not present any major difficulties, nor does the GPX track guidance.

Go for it, it's great!

Three times, I climbed Mont Ventoux starting from the hamlet of Les Valettes, following the route via the Sommet de la Plate and the Pic du Comte. But I never came down via the Rochers de Cachillan.
I stopped at the Chapel of the Holy Sepulchre because, for once, it was open!
I returned once again to the Roman quarries, even though I know the place well.
Two chamois watched me from above.
I reached Pic du Comte in 2 hours and 40 minutes, and 20 minutes later, I was at Col du Comte.
I climbed through the forest and along the track to reach the Mont Serein station.
I took a quick break to eat before starting the climb up Ventoux. It took me 1 hour and 15 minutes from the campsite.
Wind, mist and a few drops of rain at the summit, and with no fleece or jacket, I didn't linger.
Quick descent via the ski slopes, walking under the pylons.
It's quite steep, but it saves you from having to walk back through the resort on the road!
In 45 minutes, I reached Grand Valat (1,344 m), where there is a junction to go directly down to Les Alazards or back via the Col du Comte. I added 4 km to my route because I prefer to go down via the Col du Comte rather than take the slippery, stony and leg-breaking route directly to Les Alazards.
I reached "Le Plan" (605 m), where you rejoin the road in 1 hour 35 minutes, as the path from the Col du Comte is very pleasant and easy. Beautiful views on the way down.
A final hour's walk on the road and trail back to Les Valettes.
A 9.5-hour hike, including a 45-minute break, 1,800 metres of elevation gain and nearly 34 km.
I plan to complete this entire suggested route.

Nice walk,
but be careful on the forest path after the hamlet of Les Valettes, number 2. The path is private and the farmer is unfriendly and aggressive.
I had to change my route and catch up with the GR4 at Alazard until I reached the Col du Comte.
Sinno. Beautiful hike.

A very beautiful and pleasant walk, not very busy except for the final climb to the summit via the GR... which is to be expected! However, a few details about the route:
point 1: the fork takes us onto private property with a really unfriendly farmer and a fairly high fence with no gate, so we had to turn back and go around the mountain. In fact, at the fork, follow the sign on the right for "combe Arnoux". At the next crossroads, continue straight ahead, leaving the quarry on your left. At the next intersection 300 metres further on, turn left onto a wide path that climbs steeply. You then come to a crossroads where you turn left. Here, a small, half-broken sign for "combe Arnoux" shows you the way. The rest of the route is fairly well signposted, and you end up behind the fence of our friendly farmers!

Point 21: there is no fork; you will come to a woodcutter's hut. Turn right onto the main path that climbs uphill and continue along it until you reach the departmental road and the "Près Michel" signpost at point 22.

Point 27: the red and white markings are very fresh/recent and take us back to the main path we took 10 minutes earlier. In fact, you have to take this small path and go straight down into the woodcutting area. Do not follow the red markings on a white background, which take us to the right. We rejoin the GR 200 or 300 metres further down.

Point 29: at the olive grove, the path is quite overgrown. I didn't see/pay attention to the path indicated on the map, so I walked along the fence and took the path opposite (instead of going further to the right, I suppose). This path ends up being well marked and is in fact almost parallel to the planned route. They meet up a few hundred metres further on.

Circumstances: hike with bivouac at Mont Serein. Sunny, very little wind, cold night. Map and compass, no GPS. From the start to the Cachillan rocks, magnificent due to the varied topography, landscapes and difficulties. After a lot of sheltered terrain and nothing but descent. On the second day, there were two or three minor uncertainties about the route. Before point 18, don't hesitate to descend along the ridge, and at point 21, before coming out into the open in the boxwood, be careful not to miss the green markings. At 23, don't look for the cairn, which has disappeared, but fortunately the sign is there, so dive into the tall boxwood and swim. During the preparation, I had some apprehensions when reading the information sheet, but fortunately these were overcome because it was really superb (the route remains passable and fairly well marked). Thanks to Visorando.

I am planning this hike in a few days, with a night at the Mont Serein campsite, but I am unsure about how easy it will be to follow the route description. If anyone has followed it, I would really appreciate some comments.

We did the hike in two days, staying overnight at the Mount Serein station in a guesthouse.
Good description of the route. The GPS and .gpx track are useful for making sure you don't miss any turnings.
Day 1: Beautiful views to the right and left on the ridge of La Plate summit.
Day 2: Austerity and cold at the summit of Mont Ventoux. Beautiful rocks and sharp limestone pavement on the ridge of the Cachillan rocks.
It's nice not to have to follow the GR trails all the time and to be able to navigate using the terrain. Well done on this route.
