There is no ibon, it doesn't match the photos. It's just a pond for the animals to drink from.

Exceptional spot. To fully enjoy it, sunrise or sunset are preferred.

Pleasant cabin and well located for getting to Pic d'Anie in the early morning. During my visit (10/2023) only the SAS entrance to the cabin was accessible. The other 2 rooms were locked. Presence of a water point just a few meters from the cabin (be careful of the noise generated if you spend the night there).

The peak of Arlas forms a beautiful, incisive tooth, which stands out particularly well in the surrounding panoramas. On this point, you are ideally placed to admire his profile. The peak rises to an altitude of 2,044 meters and is located between Navarre in Spain and the Pyrénées-Atlantiques in France.

This mountain pass is on the Franco-Spanish border. It is overlooked by the peak of Arlas which rises to 2,044 meters. From the pass, you can admire the valleys of Roncal in Spain and Haute-Soule in France.
