Very busy hike in season, snow is abundant on this route in April, remember to equip yourself with a good pair of shoes and take poles for more safety. We are in the low season in April, no signal at this location, wildlife is exuberant at the moment. It is advisable not to hike alone.

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!!!

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. This point marks the end of the asphalt road. It's definitely worth getting here because the road is magnificent and gives you the opportunity to ride peacefully in the heart of a grandiose 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 climb with a small tourist train pulled by a tractor. Personally, I preferred this passage to the road to the Gavarnie cirque.

One of the best scenarios where we can reach the Pyrenees by road bike. Beautiful glacial cirque where we will never encounter much traffic. Apart from that, cars cannot access the last 2 km. It's a relatively unknown port but aesthetically it's a 10.

This pleasant gîte is located at an altitude of 1,837 meters on the road to the Cirque de Troumouse. It is the ideal place to take a break while tasting many local specialties in a grandiose setting.
