One of the most inhospitable and spectacular mountain passes in the eastern Pyrenees, with several slopes, all of them very difficult.
The landscape is wild and wonderful. You can breathe absolute tranquility and you can dedicate yourself exclusively to enjoying the views, the horses, the sheep, the cows and the suffering on the bike. The summit is on the border with Spain, although there is no road that crosses the border, so the pass runs entirely in France.
I have climbed it on 2 of its slopes. The first time I climbed it on the slope that crosses the Col d'Orgambide, on the D428 road, which starts from Estérençuby. The first 3 km are very easy, until you cross the detour to go up to Artaburu, where the road begins to have slopes of more than 10%. From there, to the summit, the climb is very hard, around 9%, on a very rough and bumpy road, with a lot of humidity and crossing a wonderful beech forest. Once you reach the top of the Col d'Orgambide, you turn right and continue climbing for another half kilometre with a gradient of 11%. There comes a small descent, to face the last 3 kms, the first 2 very hard with several 13% gradients. The last kilometre is very easy and has panoramic views that are simply wonderful.
The second time I climbed it on the side that starts from Arneguy and Ondarolle. This side is harder than the previous one, with a central section that is hellish, being 6 kms at an average of 10%, and a very hard km at 12% and 18% gradients!!! The final part is more gentle. You cross the Croix de Thibault in the penultimate kilometre of the climb. The final kilometre is very gentle and with beautiful and exciting panoramic views.
