Pass with a beautiful view! If you go up the Hourc road, it's a steep climb at the end, but it's worth it!

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.

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.
