The road from Melles is in good condition up to the last houses, then it becomes much more sporty, with quite a few very rough and rocky sections. But the views are sumptuous!

Beautiful climb up Col de Menté. Although not a really famous climb it is a beautiful one, with nice hairpins inside the forest and beautiful views at the end.

Beautiful asphalt road whether on the Ferrere side or the Luchon side. The climb on the Ferrere side is much more pleasant. I recommend this pass.

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.

The ski lifts are very useful for practicing winter sports. Alpine skiing would not be possible without ski lifts. Now, in summer they are a sweet temptation that must be avoided at all costs. This lift is a good alternative for the cyclist who is accompanied by someone who does not go up on a bicycle. While the cyclist climbs SuperBagnères on the road, the companion climbs to the ski resort by lift, finding himself at the top of the pass.

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.
