Cabane d'Auruzan (1620m) walks

More magnificent lakes are on the agenda, with the added bonus of a short chairlift ride on the Andorran side to rest your legs before the descent to L'Étang de Soulcem, which is very challenging in the last section.

This is the sixth and final stage of the Tour des Géants des Trois Nations, which has a steep descent (1,800 m of elevation loss, which will hurt your joints) to return to the starting point of this journey. This stage passes by the Fourcat Waterfall, the beautiful Izourt Pond and the forests of Goulier-Auzat and Montcalm.

The first stage of the journey, the shortest and easiest, to warm up your legs, passing through the Bois de Fontanal and the Étang Sourd to the Refuge du Pinet. The elevation gain is still significant.

A magnificent hike in the upper Ariège in a spectacular setting. On the agenda for the day are the Etangs du Picot and the two Etangs Fourcat, which quickly make you forget the intense effort required during the climb.

The fifth and final stage of the high-mountain route passes by the iconic Pic de Tristagne, which towers over the many lakes in the surrounding area, and its short, fairly exposed ridge route, before returning to France via the magnificent Étangs Fourcat site.

After our chairlift ride, we descend towards the Soulcem lake on the Ariège side. We enjoy the beauty of this glacial valley, the Soulcem lake, the Mérens horses grazing freely, not to mention the numerous orris that line the route. It is a wonderful but particularly challenging end to the hike between the Caraussans lake and the Soulcem trail.

The second day is a high-mountain stage passing through the highest point of this itinerary: Pic d'Estats, as well as two other peaks over 3,000 m nearby, Pic du Montcalm and Pic de Verdaguer. The route is largely over scree and rocky terrain, which will greatly appeal to mineral enthusiasts. The trail largely follows the Porta del Cel hike and the GR®T61. Although not particularly technical, this stage should not be taken lightly due to its altitude (three peaks over 3,000 metres), its length, its elevation gain and its trails composed of loose stones that can make progress difficult.

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.

From the start of the hike, pay attention to the common white and red GR® T66 and GR®10 markings, as there are several crossroads and forks in the trail. Please note: the hike is in open terrain until the descent into the forest, well after the Rieutort hut.From the refuge, via the Crête des Isards and up to the Col de la Didorte, what a view! Of course, you need to be very careful on this ridge, which is often steep and jagged. But as soon as you stop, you can enjoy a 360° panorama.The steep descent to the Rieutort hut is on a narrow but safe path, offering beautiful views. The return to the road is not easy, but the path (GR®T66), although steep in places, is well marked throughout the descent.

This second day is exceptional. Most of it takes place on ridges from which you can see the Ax 3 Domaines resort on one side and the Plateau de Beille on the other. And everywhere, there are lakes and breathtaking landscapes. This stage is long (nearly 18 km), but you'll never want it to end before you descend into the valley through the forest. It's best to have someone waiting for you in the valley, or else you can reach Ax-les-Thermes on foot or by bus. Be aware that as you will be taking photos and spending time admiring the landscape, you should allow 6½ to 7 hours for the whole trip.
