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.

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.
