The Col du Portillón is a short but intense mountain pass that connects the Aran Valley to France via a narrow, shady road through forests. Its ascent, with its pleasant slopes, is highly appreciated by local and professional cyclists.

A challenging climb from Luchon, but still worth it.

Strenuous but worthwhile climb.

It is a port that, despite not having the characteristics of its neighbors, it is important that we do not lose respect for it. From Bossosst it climbs really hard, from Luchon a little more gently, although they don't give anything away.

A real pain to climb, not because of the difficulty but because of the fact that it is extremely busy, and that we have plenty of time to breathe the exhaust pipes of the tower which makes us feel doubled.
