After breakfast, it closes for a while for cleaning. Fill up your water bottle before heading up, as it's a scarce resource up there.

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

Emblematic peak of Canfranc, common at the start of the ski touring season, and recommended family outing to Ibón de Escalar in summer. It is a short, easy and beautiful ascent to Ibón de Escalar, and with a final climb to the peak only for mountaineers.

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).
