Climb Description

Col du Portillon is a climb in the Pyrenees which finishes at a border crossing between France and Spain (Catalonia). The ascent from Luchon is inconsistent with some sustained steep sections, which makes it a more challenging climb than the average gradient suggests.

The scenery here is quite typical of the nearby Ariege Pyrenees region. It is largely forested and, although the scenery is pleasant, there are few spectacular views - even at the top of the climb.

The climb has been used in both the Tour de France and the Vuelta a España, although never as a stage finish. Riders leading the race over the col have included Joaquim Rodríguez and Richard Virenque.

Col du Portillon is open throughout the year subject to weather. Short term closures are possible in winter, but the relatively low altitiude of the climb means that it often stays open even during the coldest months.
