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

A fairly difficult hike when you're not trained (which was my case) but not impossible if you take your time and go at your own pace. On the other hand, it's a very beautiful hike! The landscapes are magnificent. There are two parking lots, the Masousa parking lot and another higher up which saves 45 minutes, but the road is very bumpy.

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 rises to an altitude of 2,044 meters and is located between Navarre in Spain and the Pyrénées-Atlantiques in France.
