A very beautiful summit just before the Pic du Cagire. It offers a very beautiful view of many peaks: Pic de Midi de Bigorre, Aneto, etc. You can also see the Boutx ski resort!

I would like to make hikers aware that this route can become particularly dangerous in winter, particularly because of the ridge towards the Pas de l'Ane which can become covered in ice. In this case, ice axes and mountaineering crampons are essential. 2 people died at this location on 1/1/2025, which triggered access bans. I have taken steps to have these bans lifted while raising awareness in a constructive way. Take the time to find out about the snow conditions before undertaking this hike. Enjoy your walks!

One of the mythical Pyrenean ports of the Tour de France, known largely for the tragic fall of Luis Ocaña in the 1971 Tour when he was leading the general classification. Its 2 aspects have a lot of crumbs: - west slope that starts from Saint Béat: it is the hardest. It is 9.7 km with an average slope of 8.7%. It is a very constant climb, with a small break when passing through Boux. The first part is a little harder and uglier since you barely have any views and you go up through the middle of a valley. The final part is spectacular with its many horseshoe curves, good panoramic views and the monument to the place where Luis Ocaña fell. - east slope: it is longer, with an initial section of 7 km very winding with a slope of 4%. It also has a break in its intermediate zone. Once the hard part starts, it is also very constant, like the west slope, although the average slope is 7-8%. This aspect has even more twists than the previous one. For more information, consult the profile published by cylcingcols.com -- > http://www.cyclingcols.com/col/Mente

Spectacular path that goes towards the town of Canejant. It is hard because it saves many meters in a few kilometers but it represents the old road that leaves you at the gates of the town. Stone curves that zigzag.

A small hermitage at the end of the village of Les that is perfectly preserved. The chapel is on one side of the road so it is not difficult to see it when you run past it.
