Col de Couraduque is a Cat HC climb to a cross-country ski station in Val d’Azun. It is a really great climb for cycling. From Argeles-Gazost climb in the direction of Col du Soulor until the village of Aucun. In Aucun take the right turn and you have 7km to the summit. It starts off very steep but eases off after 2 km. The road surface is fantastic and there is little traffic. From Aucune the climb is Cat 2, 7km at 8%. At the summit there is a nice cafe with a beautiful view from the terrace. For quieter roads climb through Saint-Savin and Bun to Aucune.
Can also be climbed from Argeles-Gazost via Gez. This route is much harder and the last 5km are gravel.
