Description of the walk

Access: From Saint-Chaffrey (Serre Chevalier), take the Col de Granon road. It takes about 20 minutes by car to reach the large car park at Col de Granon.

(S/E) When you arrive at the car park, take the first path on the left (signposted Lac de l'Oule).
Continue for about 300 metres until you reach a fork and a sign for Lac de L'Oule.

(1) Take the path on the right. You will reach Col des Cibières (altitude 2,525 m).

(2). Take the path that climbs opposite (signposted Porte de Cristol) to reach Crête de la Gardiole. As you climb, you will notice a stone wall on your right. The climb becomes steeper as you reach the summit of La Gardiole (altitude 2,760 m), which is occupied by an observation post. There is a beautiful 360° panoramic view.

(3) Descend on the opposite slope (towards the east) via a small, very discreet and unmarked stone path and, a few metres further down, continue south to reach a fork (altitude 2,570 m).

(4) Take the path on the left (not marked, heading north/east) to reach the Col de l'Oule.

(5) Descend the north slope opposite to Lac de l'Oule (altitude 2,430 m) via theGR®57marked in red and white.

(6) Return to Col de l'Oule via the same route.

(5) Follow theGR® trail to the left for 300m, then leave it (on your left) and continue straight ahead (south) to cross the Plateau des Cibières. This trail is marshy in places and you may see a few small lakes.
Approach a ridge and finish at the Col de Granon car park (S/E)

Beautiful 360° views from La Gardiole. The climb to the summit and the descent are rocky but not difficult.
As we set off early (before 8 a.m.), the trail was quiet, but when we returned around midday, the car park was full.
There is a refreshment bar at the Col de Granon.

This beautiful, accessible hike is very popular in August, even if you set off early. The route via La Gardiole is ideal as it is less travelled. The view from the summit is well worth the effort.

The access road to the Granon Pass is very narrow. It is a very busy place in summer.
Going via La Gardiole allows you to avoid the crowds.

We did this hike on 24/7. The route is not always marked but fairly easy to find, except on the summit of La Gardiole where you have to find the path down. From La Gardiole, the descent is quite difficult at first.
It is not at all a family outing (unless you only do the Lac de l'Oule).
The view from La Gardiole is magnificent. The lake is superb.
Thank you for the description.

Hello,
Thank you for organising this walk. We set off at around 2.30pm. There was no one else climbing up and down the summit of La Gardiole. There were a few hikers on their way back from the lake, but it wasn't crowded.
A pleasant walk with beautiful views.

Nice walk, but it's a shame to have to go back and forth to see the lake.

A very beautiful hike to do with the family. Beautiful view of the lake at the top of Gardiole indeed. Just be aware that you have to make the short (steep) climb from Lake Oule to reach the return trail, which can be a bit tricky for children after lunch by the lake. The lake is very beautiful, with a superb shore where you can relax and swim.

Beautiful hike. Very beautiful view from the summit of La Gardiole, where you can also see Lake Christol and Lake Rond on the left. On the way back, between points 5 and 1, at point 2389, we joined the military road on the left. Worth seeing.

An easy walk accessible to all, beautiful surrounding landscapes, magnificent lake (the water was 15°C that day, I took a dip, it was cool and pleasant). Option to return via a different route from the one taken on the way there.

A beautiful hike that feels like you're in the high mountains. On the way back, we took the GR trail to the Porte de Christol. Walking on the GR trail isn't very interesting; the small paths are much more pleasant, but unfortunately they are poorly marked.
