A steady Tour de France climb to 1,570 m in the Ariège Pyrenees, tight wooded hairpins out of Aulus-les-Bains giving way to high pasture near the Étang de Lers.
The Col d’Agnes climbs to 1,570 m on the D8F in the Ariege Pyrenees between Aulus-les-Bains and Massat, passing close to the Etang de Lers. It is a steady, scenic Tour de France climb through forest and high pasture with broad mountain panoramas near the top. Mind tight wooded hairpins, livestock on the open upper slopes and damp shaded tarmac.
