The view is less impressive than at Lac du Barbat, but it is the gateway to the Cauterets valley, with the Lys ridges (Cauterets resort) to the left and the Ilhéou lake below, which cannot be seen from this spot.

Splendid scenery! Warning: difficult route, rock climbing, slippery stones. In September, there's almost no snow, which is the perfect time!

For the first 20 kilometers, the climb is gentle, crossing the picturesque landscapes of the Gavarnie cirque. Then once you reach the town of Gavarnie, the real climb begins, with much steeper gradients that can exceed 10%, reaching an altitude of 2,200 meters.

A magnificent cross-country route that I never tire of: France ➡️ Col des Mulets ➡️ Spain ➡️ Col d'Arratille ➡️ France 🤩 In this sense, although the climb to the Col des Mulets from Les Oulettes may seem steep, at least at the start, it is done quite quickly, in less than 2 hours. In September, you will no longer find snow on the path that connects the two passes. One point of attention, however: as you approach the Col d'Arratille, a passage may seem tricky for some and will require a certain agility. Indeed, a short rocky section, requiring the support of the hands, leads to a flat area from where you will continue your path without difficulty. At the Col d'Arratille, you will come across its lake, a jewel whose colors will remain in your memory for a long time.

Splendid stony passage in Spain along the cirque between the two passes to return to France.

The 19km to Gavarnie are easy and on foot, 705 meters in altitude. The next 10 kilometers are tough and grueling with about 830 meters of elevation gain. Moreover, you go above 2000m, which also makes it more difficult.

29.9 km of ascent with a gradient of 1,524 m and an average slope of 5%. It is one of the hardest climbs in the Pyrenees, especially due to its length and the hardness of its last 10 km, once you have passed the town of Gavarnie. The first 19 km, from the Luz exit to the town of Gavarnie, are very gentle, with flat and rest areas. You cross the village of Gèdre, from where the road leading to the Cirque de Troumouse starts. The road is in perfect condition and is wide. The only drawback is the traffic of motorcycles and motorhomes in summer. The last 10 km, the hardest, come after passing the town of Gavarnie. After a short break the average slope is 8.5%, with long areas maintained at 10%. It is a colossus in every rule. I recommend taking photos at its summit and, if possible, walking along the road in terrible condition until you reach Port de Boucharo, a mountain pass on the border between Spain and France.
