Description of the walk

Heading towards Saint-Lary-Soulan, at the exit of Guchen, follow the signs for Vielle Aure via the D19. Pass the Le Lustou campsite and the Chapelle d'Agos, continue for about 500 m and park in a small car park on the right at the Croix de Housdarou, where there is also a picnic table.

(S/E) Take the path that climbs to the left of the road when coming from Vielle-Aure.

(1) After 150 m, at the fork, turn left and pass the slate quarry. The winding path is steep.

(2) Follow theGR®105on the left (red and white markings) and, at the first fork, leave theGR® and follow the path that climbs up to the right. Ignore the paths coming from the left and continue climbing through the woods. Pass a first barn, then two more.

(3) At the edge of the woods, you will come to the summer pastures.

(4) After two barns, turn right, then right again between the barns at the fork that follows.

(5) Pass a watering trough and continue towards the ridge (north-east).

(6) Follow the ridge to the left, towards the south-west, pass the summit near the Granges de Grascouéou and continue west-south-west along the ridge.

(7) At the signpost, turn left (south-east) and descend along a fence. Ignore a path on the right and, further on, a perpendicular path.

(8) When you reach a crossroads, take the track on the left that climbs up to the barns.

(4) Then take the same path you took on the way there to return to the car park (S/E).

Steep on the climb, then fairly flat around the barns. Fast descent. Nice view of the mountain

Great hike. Done in mid-October under blue skies.
The climb is steep from the start but manageable.

A route planned long ago by our hiking club, for snowshoeing. Unfortunately, there was no snow, so it was a beautiful walk, just like in summer
Departure point changed to the SOULAN car park and route extended after Granges de Grascouéou

A GPS-tracked route with no difficulties.
As soon as you leave the forest, the view is splendid and potentially windy. Follow the ridge on the right to enjoy it to the full.
A panoramic view of the Saint-Lary-Soulan resort, where the snow was melting in January 2024...
On the way back to point 2, you can continue straight ahead to extend the route slightly and descend on another trail.

We did this hike on 6 May in beautiful weather.
A beautiful 950-metre climb right from the start to the barns. Extraordinary views of St Lary, Azet and Plat d'Adet.
The other side offers views of Aulon.
We preferred to complete the loop with the GR10 just after point 8, which brought us back to point 2.
We took our time (picnic and nap) and it took us 7 hours
Not to be missed!

A very beautiful hike, quite a strenuous climb, the trail from AGOS is very steep.
A beautiful 360° view at the highest point.

Between the heat and afternoon storms, we set off at 7:45 this morning and decided to return via the GR10 towards Vielle Aure. A beautiful 360° view at the highest point.

• Edited:

It is possible to avoid getting lost at the summit by staying on the road, but this makes the route considerably longer.

Not much marking, which is a shame because when you're in the sea of clouds, it's easy to get lost. You have to be careful and not set off if it's cloudy.

I didn't quite follow this route: I climbed up from Vignec. Whether you start from Agos, Vieille-Aure or Vignec, you have to be prepared for a two-hour climb with no flat sections and significant elevation gains. The only thing missing is a lift, but that's what we came for, right? I went up via Vignec and then Soulan. To climb up to the mountain pasture after Soulan and reach the ridge, it's best to take your time, as the slope is steep and straight. Once on the ridge, the world is at your feet. You may see vultures or what remains of carcasses. The descent is also interesting, with several viewpoints.
A superb hike that doesn't take much time and leaves you plenty of time to linger on the ridge. It took me a total of four hours, setting off at dawn to avoid the heat of the day.

Great hike done in early March after snowfall during the night, with bright sunshine at the summit – what a beautiful sight!
This hike offers superb views of the surrounding peaks, reached after a 4 to 4.5 km climb with an elevation gain of around 740 m.
At the top, walking along the ridge gives you a 360-degree view.
Visorando is very reliable for finding your way around, as there are very few signposts.
We chose to do a loop, descending via Soulan, then the village of Vignec before returning to Vielle-Aure, a very pleasant 12 km route.

A beautiful hike to barns that were still in use until the 1960s, some of which have fortunately been maintained or restored.
We did it with two variations. First, we started from the village of Vielle-Aure, which at an altitude of 950 metres offers beautiful views of the valley and Saint-Lary, and rejoined the route just after point 2. The climb through the forest is a bit challenging, but not difficult if you are in good shape, and above all it is shaded by the trees. There are superb views of the barns and the ridges. You can see the mountains to the south and the Arbizon to the north. A real treat.
Return with the second option: just after point 7, we turned off towards Soulan and then returned via Vignec. The descent here is less steep (except at the very beginning) than via the GR 10.

A very beautiful hike with magnificent views of the mountain pastures. We made a slight change to the route at the start, leaving from the Lustou campsite and returning via the GR10 trail to Vieille Aure, instead of heading back to markers 4, 3, 2 and 1 as indicated in the hike itinerary. The climb was a bit tough, though, and the ridge was a little tricky to find at first, but we had an IGN map to help us, so it wasn't a big problem.

A beautiful hike in the sunshine, with a few clouds on the surrounding peaks... The climb is indeed tough, as my partner confirms . We got a little lost on the ridge when we had to follow the ridge to the left, as the path disappears a little in the grass, but thanks to the GPS track we were able to find our way back. We descended via the GR10 to Vielle-Aure to add some variety to the return journey

Hike ruined. We set off under cloudy skies, navigated using GPS in thick fog, and saw the sun again when we returned to the valley.
Normally, it should have cleared up, but the clouds remained stuck to the peaks.
On the plateau, we saw gentians by the side of the path and cows on the path.
Many thanks to the GPS and the good route.
