Points of interest

The Sierra y Cañones de Guara Natural Park (in Aragonese Parque natural d’a Sierra y as Foces de Guara ) is a natural park in the province of Huesca and covers the regions of Alto Gállego, Hoya de Huesca, Sobrarbe and Somontano de Barbastro.

Thanks to its geology this area has become somewhat a Mecca for the practice of canyoning and climbing (In fact some would say that this is the area in Europe that first developed the sport of canyoning). The ravine of the Balcés river is more than 20 km in length and has cliffs as high as 800 m. The Grallera Alta de Guara chasm which has a vertical drop of 277 m.

The whole area is noteworthy for its spectacular scenery and wildlife.

The climate is a hybrid of Atlantic and Mediterranean due to its location between the Pyrenees and the Ebro Valley . This marks the differences between the vegetation of the south and that of the north.

There are four rivers that cross the mountains and these have created the characteristic canyons: they are the Alcanadre, Flumen, Guatizalema, Vero and Mascún.

On the northern slopes gall oak occupies large areas, followed in height by the forests of scots pine and beech groves. At higher altitudes there are forests of black pine and spruce.

On the southern slopes the Mediterranean forest takes control with holm oak being the predominant tree along with scots pine at higher altitudes.

Around the natural park the scrubland is also one of the most important plant formations especially boxwood heathers and kermes oak.
