Pic de Saint-Barthélemy via Moulzoune

Superb viewpoint over the entire eastern part of the Pyrenees. The Pic de Saint-Barthélemy also offers an exceptional view of the plain to the north. It is easily identifiable on a clear day from the motorway...
The route combines beech forest, where the small Lac de Moulzoune nestles, two old quarries, grassy hilltops overlooking two high-altitude lakes, a small forest of mountain pines and ends with a stony ridge covered with rhododendrons.
Pics de Soularac and Saint Barthélémy from Montségur

Loop starting near the village of Montségur, via the peaks of Soularac, at 2,368 m, and Saint Barthélémy, at 2,348 m, then return via the Diable and Truites lakes. This is a fairly demanding circuit in terms of elevation and the nature of the trails.
Étang de Moulzoune - Pic de Soularac - Pic de Saint-Barthélémy

Loop starting from the Étang de Moulzoune via the peaks of Soularac and Saint-Barthélémy. To be done between June and November, checking that there is no snow on the north side (visible from Lavelanet), as access would be difficult.

Ax 3 Domaines Plateau du Saquet - Rulhe Refuge
This is a magnificent hike that starts from the Plateau du Saquet, and therefore the Ax 3 Domaines ski slopes, and ends at the Refuge de Rulhe, where a good local rataf will do you good. Once you reach the top of the resort, long desert plateaus await you before you descend into the austere scree slopes at the foot of Rulhe and finish sliding down to the Refuge de Rulhe. This first stage is wild and challenging, in the scree slopes. Be careful on the descent from the Col de Lhasse, which is very steep (but the GR® is well marked).
From Ax Trois Domaines/Le Saquet to Castelet via the Refuge de Rhule
A long hike in Haute Ariège to admire the lakes, ridges and magical landscapes with a stop at the ideally located Refuge de Rulhe, an opportunity to taste the local rataf'. On the second day, you can admire the whole area from the ridges.
Laparan - La Peyre - Passerelle - Fontargente - Aston - Refuge du Rulhe

Please note: the approach walk along the road is the only part of the hike that is in the shade if you set off early enough in the morning. This is the only way to complete this loop. It may seem tedious, but the landscape is very beautiful.The hike can be classified as quite difficult. After the footbridge over the Ruisseau de la Coume de Varilhes, the path is not easy: steep, with steps, a paved scree slope, a ledge to cross, etc. But once you reach the top, you will be rewarded. Then the GR®T66 from the largest of the Étang de Fontagente lakes to the refuge is more of the same. This is definitely a mountain hike.
Forges d'Orlu - Refuge d'en Beys via Naguille and La Couillade d'en Beys

Significant elevation gain over a relatively short distance. Magnificent landscapes in a very wild mountain setting. Numerous ponds along the way. A magnificent view from the Couillade d'en Beys. The effort is rewarded throughout the day.
⚠️ Stay on the marked trails: GRP® Tour de la Montagne d'Ax, as you are on the edge of or within the National Reserve.
