Sierra y Cañones de Guara Natural Park

The Sierra de Guara and the Cañones de Guara are a landscape between two climates, characterised by distinctive vegetation: dry to the south and lush to the north.

The park covers part of the municipalities of Abiego, Adahuesca, Aínsa-Sobrarbe, Alquézar, Arguis, Bárcabo, Bierge, Boltaña, Caldearenas, Casbas de Huesca, Colungo, Huesca, Loporzano, Nueno and Sabiñánigo. Its altitude ranges from 430 metres at the river Alcanadre to 2,077 metres at Tozal de Guara. The landscape has a karst topography, full of caves, hills, chasms and canyons. The climate is somewhere between the Atlantic and the Mediterranean, due to its location between the Pyrenees and the Ebro Valley. This marks the contrast between the vegetation in the south, which is drier and has an abundance of holm oaks, and the north, where there are leafy species such as beeches. Four main rivers run through the mountain range, creating its emblematic canyons: the Alcanadre, the Guatizalema, the Vero and the Mascún.
