Climb Description

Col du Portillon

Col du Portillon is a climb in the Pyrenees which finishes at a border crossing between France and Spain. 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.

Port d'eth Portilhon 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.

Port d'eth Portilhon 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.

Other sides

Col du Portillon can also be climbed from the Spanish side, where it is known as the Port d'eth Portilhon.
