Difficult
Departure from Oô (Haute-Garonne)
Starting from Les Granges d'Astau, there is a long climb with some steep sections, made more pleasant by the presence of several lakes. Lac d'Oô and its inn, and Lac d'Espingo in its magnificent setting are ideal places to stop for a break. After Lac du Saussat (pronounced Sa-ou-sat), the much smaller Lac de la Coume de l'Abesque marks the start of the steep, winding climb that leads to a plateau dotted with smooth rocks and small lakes, and then to the Jean Arlaud refuge.

Departure from Oô (Haute-Garonne)
A more demanding hike than it appears, passing by famous lakes in the Pyrenees: Lac d’Oô and its superb waterfall, Lac d’Espingo, Lac de Saussat and Lac du Portillon. The view from the summit of the Tusse de Montarqué is magnificent, set in a cirque surrounded by numerous 3,000-metre peaks, which may inspire ideas for future hikes.

Easy
Departure from Oô (Haute-Garonne)
A gentle descent after the exertions of the previous days. From the Col d’Espingo, the Lac d’Oô below accompanies us for a long while. Once at the stone bridge, don’t hesitate to make a short detour to the Auberge du Lac d’Oô, where you can enjoy the view of the great waterfall, which will help you forget, if only for a moment, the increasingly obvious and cruel shortage of water. The return to Les Granges d’Astau brings this getaway in one of the most beautiful spots in the Luchon area to a pleasant close.

Very difficult
Departure from Castillon-de-Larboust (Haute-Garonne)
A truly beautiful walk leading from the Vallée du Lys to the Hospice de France via the Lac Vert. The route is varied and the elevation gain is certainly significant, but this is more than made up for by the magnificent views over the Haut-Luchonnais and the ridge marking the border with Spain.

Departure from Cazeaux-de-Larboust (Haute-Garonne)
This first stage, which serves as an approach walk, is difficult. The climb is steep and sustained along the Torrent de Houradade up to the junction at the Cabane de la Coume. Continuing the route to reach the Cabane de Pratlong allows you to catch your breath a little before tackling the final stretch via the numerous tight hairpin bends leading to the pumping station and then to the Refuge du Maupas, where the warm welcome will quickly make you forget the day’s exertions.

Very difficult
Departure from Cazeaux-de-Larboust (Haute-Garonne)
An alternative route to climb up and spend the night at the Refuge du Maupas: this is longer than the standard ascent but less busy, offering splendid views over the Lys Valley and the 3,000-metre peaks overlooking the Cirque des Crabioules. Best undertaken in good weather, as the path is sometimes poorly marked after the Anciennes Mines des Crabioules.

6 hrs
Very difficult
Departure from Castillon-de-Larboust (Haute-Garonne)
On this day’s hike, you’ll need to find your own way up to the Pic de Maupas over rounded boulders, where the numerous cairns mean you’ll have to locate the next one each time to continue the ascent to the ‘Mal Pas’, which gave the peak its name. This is the only pass – difficult to access – allowing you to cross over to the western slope and complete the ascent with a few easy climbing moves. The return will follow the same route as the ascent, with a pleasant alternative route via Lac Vert.
