The Col de Portet made its Tour de France debut in 2018, during the shortest stage of the race (just 65km). It instantly became a hit, with Nairo Quintana winning on the day, and with the steep slopes and delightful hairpin bends proving very popular with fans. Col de Portet shares a mountain with Col du Tourmalet and, with time, it may even rival its famous sibling's title as the hardest and best climb in the Pyrenees.
The scenery is beautiful throughout the climb, particularly on the upper slopes when you get above the trees and are afforded wonderful views of the high mountains in all directions.
Col de Portet is open as far as the Pla d'Adet turn off throughout the year. The final 9km are usually open from June to October.
