From Mauléon-Barousse, this 19-kilometer hors catégorie climb is completed in three stages. The first seven kilometers are fairly straightforward, then the next seven become more complicated, before culminating in a grand finale with the last five at over 9%. Even more so than on other passes, the key here is economy.

At this bend, the trees disappear and the pastures spread out in their splendor. In the distance, you can see the top of the port. At its feet, a beautiful and quiet valley, which we have climbed from Ferrère. I was waiting for two straggling group members at this point. I enjoyed the views and the tranquility like a child.

I would just like to remember that Alejandro Valverde was the first rider at the top of this pass when the Tour crossed it for the first time in 2012, subsequently winning the stage that ended in Peryagudes.

Small and very pretty town at the foot of Port Balès. It is worth stopping at the town fountain to take a breather before the climb to Port de Balès.

Port de Balès is one of the great colossi of the Pyrenees, discovered for professional cycling in the 2012 Tour, crowned by Alejandro Valverde for the first time. The two times I have climbed it it has been on its northern slope, the longest and hardest, although the southern slope is also very hard. The northern slope begins with a very nice road that runs next to the river and goes up it at a very gentle rate. Starting from a bridge, where you leave the river on the left, the hard 11 km stretch to the top begins, although it is true that there are 2 stretches where the slope softens and allows you to take a break. The last 5 km have spectacular views of the valley and the surrounding peaks. At the top, the panoramic view of the Pyrenees is incredible.
