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.

The western ascent to the Col du Tourmalet is the more scenic and the harder. Approximately 18 km (11 miles) covers 1,400 meters (1,400 ft) of elevation gain. In the lower section, the pass has a steady and easy gradient in the high single digits. After the village of Berges, there are a few double-digit climbs, after which the gradient returns to a steady gradient. Only at km (16 miles) do the switchbacks begin, and thus the steepest section, which reaches a maximum gradient of 14%. Then the monument is already in sight, and the col is in sight.

A beautiful, quiet pass. Easily accessible by mountain bike from Bederet. The trail from here to Cauterets is a dream. A must-do if you're in the area!

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.
