Cabane d'Auruzan (1620m) walks

First stage of the journey through the Haute-Ariège. A beautiful, steady climb takes you to the Étang d’Izourt, steeped in human history. This is followed by a gruelling climb up to the Orri de la Caudière. Once you’ve crossed the rustic footbridge, there’s another very steep climb up to the small Étang du Fourcat. The rest of the route to the Étang du Fourcat refuge is more gentle. A very steep climb to the Fourcat refuge with an average gradient of 17 per cent. Please note: from the Étang d’Izourt to the refuge, the gradient is 24 per cent.

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.

Second stage of the journey through Haute-Ariège.A difficult and long mountain stage (around 7 hours), to be undertaken seriously and by those in good physical condition.Shortly after leaving the mountain hut, there is a very steep climb.After crossing the first pass (2) (altitude 2,574 m), you’ll encounter rocks, snowfields, another climb and then another pass (3) at 2,640 m.From this point: tricky sections with cables and steel rungs fixed to the rock.Then the rest of the very gruelling descent through magnificent scenery.Please note that the Mounicou lodge will be closed in 2026 => accommodation in Marc: see the ‘Places to Visit’ section.

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.

A short, not too difficult hike – very enjoyable. You follow streams all the way, first through the forest, then across a plateau. A very wild, natural atmosphere. Countless spots, ideal for pitching a tent, with trees galore, majestic rocks and a fast-flowing yet calm river. A very good population of brown trout in the river. The lake, too, is teeming with fish – large brown trout and rainbow trout – to potentially delight the palates of food lovers.

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.

First stage of the 3-day hike that is circular and loops around the Étang de Soulcem. This beautiful, long stage will take us into Catalonia, first passing by small lakes and then through the Port de Bouet, through gentle high-mountain landscapes, over the grassy, undulating slopes of the Ariège and then Catalonia; we finally reach the unmanned Josep M. Monfort Baiau refuge, which is in perfect condition and offers safe shelter (sleeps 9).
