Ruisseau d'Escalès (rivière) - Affluent du Siguer 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.

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.

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.

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.

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 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.

The fourth stage is in the high mountains, easier than the previous two, allowing you to reduce your effort. Many trails through forests and woodlands make for a more bucolic and enjoyable hike. This stage presents no technical difficulties, but orientation and following the route are complicated due to numerous crossings and intersections of hiking trails. It is essential to have a hiking app and the GPX track to avoid getting lost.

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.

Third stage passing through the highest point in Andorra: Pic de Comapedrosa. A high-mountain stage with no particular difficulties apart from the climb to Portella de Baiau over scree and the descent along the somewhat exposed ridge of Pic de Comapedrosa.

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.
