Col de Puymorens is a Cat HC climb in Ariége. The summit is at 1915 metres altitude near the border of France, Spain and Andorra. It was first used in Le Tour de France in 1913 and last in 1993. The road to the col is very busy and it has very much fallen out of favour with cyclists over the last couple of decades. If climbing fro Ax-les-Thermes much of it is dual carriageway and there are lots of trucks using the route between France and Spain via the Tunnel du Puymorens.
