It is a MUST of the Pyrenees, without a doubt, that should be included in any route that crosses the Pyrenees from side to side. Any of its slopes 2 is spectacular and tough. The views from its summit are wonderful, feeling the wild side of the Pyrenees. Of course, once at the summit of this pass... you have to descend to the Étang de Lers and enjoy a quiet rest on the shores of the lake. It is a pass that has been part of the Tour de France route on several occasions, although always far from the finish line. The first professional rider to crest it in the lead was the unforgettable Marco Pantani in 1995.

A little past the summit sign of the Col du Saraillé on the way down towards the valley or Aulus is a section where the road opens up in front of your reveiling a stunning view of the mountains with a few houses in the foreground. On the left at the intersection is a little viewing platform with a picnic table where you could relax and take in the view. Or you can also take in the view as you zigzag down the moutain into the valley.

Once you go past the Col de Saraillé sign and down towards Ercé a few kilometers you get an amazing view of the small little village, the valley and the looming mountains in the distance.

The Port of Lers is a crossing point which offers a beautiful panorama where you may be lucky enough to see Mertens black horses. It is also a place which has seen the Tour de France pass many times.
