Climb Description

Port de Lers is a nice climb in the Ariège region of the Pyrenees. It has been used five times in the Tour de France, most recently in 2015 when reigning World Champion Michal Kwiatkowski was first over the summit, before getting caught on the final climb to Plateau de Beille.

The climb from Massat shares much of the same road as the Col d'Agnes, turning off just 4km from the summit. The lower part of the climb is very gentle as it follows the course of the picturesque Arac River. The top part, however, is the more scenic. The scenery opens up here with great views across to the high peaks near to the border with Andorra.

Port de Lers is open throughout the year, subject to weather, but be aware that short term closures are common in winter.
