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!

It is one of the great climbs in the Pyrenees. In my opinion it is in the Top 10 of the Pyrenees, without the slightest doubt. I like long, high, hard climbs with magnificent views... and the Cirque de Troumouse fulfills this 100%. The road is narrow and bumpy, with an irregular but smooth surface. It is the typical mountain road that suffers the passage of winters and summers. The two times I've been there, I've barely encountered any traffic. The second time was a Saturday. Traffic usually goes to the town of Gavarnie, with the Cirque de Troumouse being very untouristy. Much better for those of us who want tranquility and spectacular landscapes!!!

Although perhaps the most notable is its Romanesque parish church, expanded in the 16th century, the entire town is worth a walk through its steep streets flanked by houses with thick stone walls and slate roofs.

Access is via forest tracks in good condition. Obviously, to reach 2000m it takes a little time but the reward is worth it: the views are magnificent over the valleys and peaks at 360 degrees. A delight !
