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.

Also, stop at the Là Soulan hostel for a well-deserved break. Very warm welcome. 👍

This is essentially a 14km clockwise loop. The ascent to the peaks is pretty well marked out although I’d always suggest downloading an offline route map. It’s not particularly technical just some simple clambering over a few steep rocky sections before the 1st col (Teyech). I wouldn’t fancy that rocky section if it’s frozen mind you. After the 2 stunning peaks the rest of the loop is a few kms along the ridge before turning down back through the forest. If it’s snowy, you’ll very easily lose the path (i did a lot) so another good reason to download the route.

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.
