Beautiful port with a French side heavily covered by forest

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.

Large village where we can find several bars and shops. From here we can go up to the gate or follow the valley of Aran, either up to find Vielha or towards Les. From Les we can take the Col de Menté, highly recommended, or go in search of the Col de Balés - incredible.

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.
