Hotel Casa de San Martín
Situated on a remote and wonderfully scenic stretch of the Eje Pirenaico (Pyrenean Axis Highway), midway between medieval Aínsa and the Parque Nacional de Ordesa y Monte Perdido, is this tasteful mountaintop bed-and-breakfast with verdant valley views, stone-wall rooms, and standout down-home cuisine. The British owner knows the surrounding trails through pine and oak forests like the back of his hand, and you can explore many of them without leaving the property, which spans more than 200 acres.
