A very enjoyable climb. No steep inclines, a narrow but well-maintained road. The finish at the foot of Peña Montañesa has its charm.

Beautiful glacial cirques, interesting morphology. Fragile terrain and subject to erosion.

A fairly easy to access viewpoint which offers a magnificent view of the Gavarnie cirque and Mont Perdu Park.

From passing in front of the Héas Church to the parking lot at the foot of the Cirque de Troumouse, there are approximately 7 km with 33 curves. It is a wonderful experience. If you are also lucky and have a good day with sun, no air and good temperature, then it is a perfect plan!

The Troumouse cirque is, with Gavarnie and Estaubé, one of the three great cirques of the Pyrenees. It is the largest and wildest, peaking at more than 2100m with a cirque diameter of 4km. There are no trees or bushes on the horizon, due to the climate and the wind. It is part of the Mont Perdu massif which is located on the other side of the border. It's definitely worth getting here because the road is magnificent and gives you the opportunity to ride peacefully in the heart of a magnificent landscape. The last bends from the Auberge du Maillet are on a narrow road inaccessible to cars and bikes therefore share this end of the ascent with a small tourist train pulled by a tractor. Personally, I preferred this passage to the road to the Gavarnie cirque.
