If you come to visit the Iparralde area... you can't miss it. It's worth a visit, either by bike or after the route. It has a lot of activity and life, especially in summer.

Starting point for several climbs that allow you to cross the border and reach Spain. It is a very quiet town where you can take a break and get water. I remember that on hot summer days... the heat is oppressive because there is a lot of humidity. It is a typical town in the area where you will also find some bars where you can have a drink.

There are no words to describe the satisfaction of enjoying the wildest and most inhospitable landscapes of the eastern Pyrenees. It is one of my favorite places along this entire border area between Navarre and France. It is absolutely recommended and one of the best discoveries in the Pyrenees. All this without considering the hardness of its slopes!!!

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.

This is where you should spend the first night, as the walk to the next pilgrim hostel would be too far for the first day. But you have to book Orisson months in advance!

After a steep climb, you suddenly come to the Refuge. A wonderful place for a coffee! But after that, things get serious on the way to Spain.
