Quite accessible for a normal training level. The first section is more shaded, the second more open. Almost at the end, turn right to climb to the Peyragudes station. You can also do it at the summit with less gradient; it's a more accessible road in good condition.

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.
