Description of the walk

Parking is available below the Chaillol Tourist Office at 1600.

(S/E) From the Tourist Office, take the track opposite and pass under the ski lift.
Head towards Col de la Pisse (GR® signposting) on the track on the right. Continue along the track, pass the signs for Coustaille and Lou Dévès, then continue straight ahead towards Col de la Pisse via the Cabanes forest road. When you reach the first sign for Les cabanes, turn right.

(1) Turn right and cross the stream to find another Les cabanes sign. Turn left towards Col de la Pisse on the yellow and red marked trail, which winds through the forest on a gradual but not too steep climb.

(2) Reach the Grande Baume crossroads and continue right towards Col de la Pisse. 300 metres further on, at a crossroads, turn left. The trail climbs to Col de la Pisse, which offers a beautiful view of the Champsaur valley.

(3) From the pass, turn right onto the stony path and follow the old Mal Cros canal for a while. There will then be no more signposts, just cairns. Try to follow the cairns and the numerous and varied tracks, which all lead to the Col de Côte Longue. This section is very stony in places, but higher up it rejoins the old canal and arrives at the Col de Côte Longue.

(4) From the pass, take the path on the left indicated by a sign for Le Vieux Chaillol. Continue climbing for about 500 metres to reach La Cabane des Parisiens, the last barrier before the summit.

(5) Turn left at the hut and begin the climb to the summit. It is quite difficult, as there are many cairns and traces that are more or less visible at times, but also many rocks and stones. You will need to find a way through, trying not to follow the cairns that go to the left, but rather those on the right.
The summit section is easier and, once you reach the summit, there is a small shelter on the left with a hiding place for the guest book. A few metres further on, the true summit (3,163 metres) offers breathtaking views.

(6) Descend by the same route (if you can find the same cairns) or by another trail to La Cabane des Parisiens.

(5) From the hut, turn left onto the path along the mountainside that passes the remains of the canal and leads to Lac de Mal Cros.

(7) From the lake, return to La Cabane des Parisiens.

(5) Descend to the Col de Côte Longue (4) and then to the Col de la Pisse (3) via the same route as on the way up. Begin the descent towards Chaillol Station - Le Chevalet, still following the same path as on the way up.

(2) At the Grande Baume junction, turn right towards Le Chevalet and continue downhill.

(8) When you reach the Le Chevalet junction, turn left towards Chaillol Station - Les Cabanes. The descent continues along a beautiful forest trail and returns to the Les Cabanes crossroads.

(1) Turn right onto the track that leads back to Chaillol station and the car park (S/E).

Hello
It was my grandchildren who went to Chaillol on Saturday; everything went well. They saw the broken-off part of the cross.
Thank you

For the final stretch, the easiest route follows the ridge to the right, above the Parisiens’ hut, and then climbs along a vein of green-grey schist.

I set off from Saint Michel de Chaillol (1,400 m) in July 2026, hiking solo. The route is a steady climb and very shaded at the start (which is pleasant in July during a heatwave).
Set off fairly early to avoid orographic thunderstorms in the late afternoon.
Then, from the Torrent de Front Froide onwards, the dense vegetation and pretty flowers give way to more sparse growth (I stuffed myself with blueberries!).
Up to the Cabane des Parisiens, the path is clearly signposted.
From the ascent of the Vieux Chaillol onwards, the path is no longer clearly signposted and you’ll need to follow the numerous cairns, which offer several options, but it’s best to take the route up to the right. The climb is very rocky, with large boulders, and you’ll spot plenty of ibex and their young.
The summit is spectacular, with a 360° view already described in other posts.
The hike doesn’t require any particular technical skills, but it is long and demands a fair amount of stamina, especially from the Col de la Pisse onwards. However, I’d recommend it 100 per cent if you’re in good physical shape (nearly 1,800 metres of elevation gain).

I wanted to do this hike since 2012 and finally did it in memory for a friend who disappeared. I started the hike at around 5pm so I could avoid the crowd and sleep at the Cabane des Parisiens. I saw many bouquetins, marmottes, etc. I started the ascension at 4.30 in the morning to catch the sunrise. It is quite easy to follow the cairns and keep the mobile app on at the same time. The sunset and sunrise were just incredible!!!
On the way down, I met too many people. It was overcrowded from 8am already...
I suggest to be an early riser and get to the top! The view is magnificent and worse the effort.

Useless app, unreliable directions...
Nothing is free, so we ended up using the old IGN blue series 1:25,000 map and a compass
We uninstalled the app on the first day of our hike.

I confirm the 23.5 km and 1,700 metres of elevation gain. The 1,583 metres correspond to the difference between the highest and lowest points. In fact, there is a 1,700-metre climb.
Thank you to those who provide such accurate route information.

On 8 July 2024, I stopped at the Cabane des Parisiens due to fatigue, while my companions continued on to the summit. The soft snow stuck to our crampons, and although it was beautiful, it was exhausting for them.

It's a good 22 km round trip with an elevation gain of around 1,500 m. It's physically demanding but not impossible for someone who is reasonably fit. I was lucky to have beautiful weather, great light and still quite a bit of snow at the top. Please note that you have to park at Chaillol 1600, as the upper car parks, which save time and distance, are closed until the end of November 2024 for construction work

I had already climbed the Col de la Pisse four or five times in the past, most recently in the snow at the end of September 2020.
But I had never continued on, even though I wanted to climb Vieux Chaillol. I don't think I was ready.
From Chaillol 1600, I climbed up to the Col de la Pisse via the balcony trail, which offers beautiful views of the Champsaur and Dévoluy.
It took me 2 hours and 5 minutes to climb the 760 metres of elevation gain. I then continued towards the Col de Côte Longue (2,690 metres).
I left the path clearly visible to cut across, and following some obvious tracks, I arrived at the Cabane des Parisiens in 10 minutes. Don't continue on the path that leads to the tunnel and the lake, but take the route marked with cairns just behind the hut.
From the Cabane to the summit of Vieux Chaillol, there is a 465-metre elevation gain, which took me 1 hour and 10 minutes.
I expected it to be more difficult, but you just have to follow the cairns all the way up, and apart from a small rocky outcrop to cross, there are no difficulties. This route marked with cairns seems to be the "official route", because from what I had read in the past, it used to be more complicated due to the many alternative routes up the mountain.
The view from the top of Vieux Chaillol is breathtaking: the main peaks of Oisans, Barre des Écrins, Ailefroide, Meije, a few peaks in Valgaudémar including Olan, as well as Dévoluy (Pic de Bure, Grand Ferrand, Grande Tête de l'Obiou).
The return trip to Chaillol 1600 took three hours, following a different route after descending the Col de la Pisse, passing through the forest and above the lake.
The hike took me 9 hours, including a 1 hour 40 minute break, covering 24 km and approximately 1,570 metres of elevation gain.
I don't think it's considered "Very Difficult", but it's for experienced walkers with knowledge of high mountains!
It was my second 3000+ hike of the summer, after the Refuge du Promontoire (3092 m), from La Bérarde.

Great hike! Magnificent 360° view. A few ibexes, but mostly vultures. A flock of sheep at the sheepfold before the Col de la Pisse. Perhaps a guard dog (heard but not seen). It is possible to bypass the area.

Very beautiful 3,000 metres, but you have to earn it (especially in the final section). A female ibex was waiting for us at the summit! I opted for the last section via a trail that was not very clear at first but became clearer further on, and on the descent I took the right-hand trail (going downhill), which was perhaps clearer but steeper (requiring the use of hands)... We made the round trip to Lac de Mal Cros, which was superb and definitely worth doing! We made the ascent between 1 and 2 on the left (in the direction of the ascent, faster and very beautiful) and the descent between 2 and 1 on the left (in the direction of the descent), which was longer and gentler but also very beautiful!
No snow problems at this time of year (just a few patches), which can be easily avoided. Luckily there are small waterfalls to fill your water bottles. Definitely worth doing again!

An exceptional hike which, given the elevation gain, distance and altitude, is well earned and requires excellent physical condition. We didn't go via the lake. From the Cabane des Parisiens, we climbed straight up. Be very careful, as the trail markings are difficult to see. Several pseudo-trails can lead you astray.
Great hike!! With chamois and ibex. At the summit, the view is exceptional, as with any hike above 3,000 metres.
Thank you
