Mont Chenaillet

Le Chenaillet, an ancient volcano located under the ocean, is of exceptional geological interest. It is an easy hike with two lakes to discover and a 360° panoramic view of Italy, the Écrins, the Briançonnais and some of the peaks of the Queyras.

Description of the walk

From Briançon, take the Col d'Izoard road to Cervières. Turn left onto the Route des Fonts (signposted, pass the church). Park in the car park after Les Aîttes near the old La Chau farms.
The La Chau farms are visible from the track and accessible via a path that you will take on the way back.

(S/E) Leave this path on your right and take the trail on the left (north) towards Lac des Sarailles. This trail then heads northwest

(1) Go around the lake on the left and continue climbing.

(2) At the next intersection (Cabane de douaniers), turn right towards Chenaillet.

(3) At the summit, descend towards the Collet Vert to the east (not marked on the map, but signposted). You will see some steps and you will have to pass a handrail (see video).
On the small pass, follow the ridge eastwards then north-eastwards until you reach an intersection.

(4) Take the path on the right heading south-east. Pass a first unnamed lake (on your right) then Lac Noir.

(5) Continue your descent south and pass the Bergerie des Fraches.

(6) Descend La Chau and enter the hamlet of old farms.

(7) Take the path heading south-west to rejoin the track, then follow it back up to the car park (S/E).

Very beautiful hike, 360° view. The software is essential. PS: signposting.

Fortunately, we had the Visorando map with us, as the signposting on the ground is inadequate in places.

A very beautiful hike. We extended it with a climb to the Col Vert and then descended to Lake Gignoux for a picnic (very busy, but there is enough space to keep your distance from other people).
Loop back to Lac Noir.
The climb to the Col Vert is very steep but short (approx. 50 m elevation gain). Take care on the descent down the scree towards Lac Gignoux, as it is slippery.
View +++ from the top of the Col du Chenaillet.

Hello, this was an interesting route because it included a trip to the summit, but it was a real high mountain valley route. The software allows you to follow the route easily and the explanations are very helpful. I recommend this route to experienced hikers.

Sheepdogs come and go, depending on the season and the shepherds. I don't think it's worth mentioning an unfortunate event on these pages, especially as it's not a recurring occurrence. The Chenaillet is a classic hike in the Briançonnais region. Hundreds of schoolchildren and geology students visit every year to see the wide variety of rocks found there. I have never heard of any dog bites. To suggest otherwise is to do a disservice to the mountains and to this classic hike in the region, which is rich in discoveries. It is best to keep your dog on a leash, especially as it may carry diseases that could infect wild animals. Otherwise, it is a magnificent hike. I highly recommend it.

No, no, it was definitely four monstrous Anatolian shepherds that attacked me, one of which was very aggressive towards my dog... https://www.woopets.fr/chien/race/berger...

I did some research on these dogs, which are
generally quite docile.
Here it is: https://www.woopets.fr/chien/race/berger...
As a former resident of Briançon, I have never come across this type of dog in the mountains, only Patous and Border Collies (black and white, but also brown and white).

Thank you very much for your reply and for calling the police. Thanks to my dog's thick coat, only large tufts of fur were torn out and there were no bloody bites, but it could have escalated very quickly. However, i would like to point out that these were Anatolian Shepherds and not Patous. They were beige with slightly brown/black heads and not very long fur. They did not look anything like Patous. I filled out an incident report and sent an email to the tourist office and the regional manager to inform them of these dogs' aggressive behaviour... I hope this doesn't happen again! In any case, it was a very nice hike apart from this incident, which really scared me...

Hello,
I have just notified the Briançon police about this. You can therefore file a complaint and show the police the bite marks.
According to the police officer, the dogs are not Anatolian Shepherds but simply Patou dogs, which are found everywhere, both on this very popular hiking trail and throughout the valleys of the Hautes-Alpes
Best regards,
The author of the guidebook

This is the first time I've posted a comment on Visorando, but what happened today is too serious.
So BEWARE, there are sheepdogs (four Anatolian shepherds and one border collie cross) between points 6 and 7. There are no signs to warn you that there are sheepdogs in the area. I set off with my dog, feeling relaxed, and found myself face to face with five dogs, one of which repeatedly attacked my dog. I was forced to kick the monster to get it to let go of my dog, then I ran away (there was no other option, as they were trying to attack my dog relentlessly) the dogs chased me for 300 metres, even though I was at least 300 metres away from the sheep and heading in the opposite direction. So if you have a pet, I strongly advise against this hike!

The southern slope, on the Cervieres side, is stunning with its small lakes, and Mont Chenaillet is truly surprising from a geological point of view. It's beautiful.
On the other hand, the Montgenèvre side is completely spoiled by the resort and the slopes.
The unique feature of Mont Chenaillet attracts a lot of people. At the same time as us, there were three buses of schoolchildren on a field trip, about 150 people in total... It was quite noisy...

Superb hike. 360-degree view. Very interesting from a geological point of view. It is one of the few places in Europe where you can see the ocean floor from when the Earth was created.
