In reply to Pyreneenemec:
I haven't stayed at this hut, but Cain is a lovely village with some nice restaurants. On the other side of the gorge, it is well worth visiting the Vega de Ario, which has a great hut, and the high peaks around Pena Santa. There is a strenuous walk to Ario from near Cain, a well-marked path up the Canal de Trea. The views across the gorge from Ario are magnificent. You can easily walk up the first peak on the main ridge of the Western Massif, Jultayu, from Ario. This drops away sheer on the Cain side for about 800 metres.
Ario hut food is excellent. They have their own chickens and make their own bread.
