An imposing mountain peak in the western Pyrenees. The ascent is very beautiful, but quite strenuous. At the top, a magnificent panorama opens up.

A beautiful valley with spectacular views, which can be accessed without difficulty (either from Ansó or from the Roncal valley), where you can breathe peace and tranquility and where you can enjoy a nice swim in the river on the hottest days of the year.

An ideal place to bathe in a high mountain river. The setting is idyllic and the water will surely refresh you! Don't hesitate to take a dip even if you have to take off your cycling shoes and jersey!

It is a gorge that allows access to the Oza Valley. Its entire route is spectacular. It is a MUST of the Pyrenees, both for the tranquility of the area, for its landscapes, and for the beauty of the route with the river next to it. One of my discoveries this year. The climb is very steep, with some ramps, but always very easy, which allows you to enjoy the gorge even more.
