I live here so I can give you advice on what to visit in Aragonese Pyrenees. If you comment about your interests I can give further information (e.g. hiking routes depending on your level, back country skiing, where to eat, camp sites open, points of interest, sights, etc.).

Eat in any "Borda". I recommend Borda Bisaltico, inside the camp site.
* Sallent de Gallego, Panticosa, Balneario de Panticosa
