Sierra y Cañones de Guara Natural Park

Nature Parks in Aragon

Sierra y Cañones de Guara Natural Park covers almost 48,000 hectares in the foothills of the Pyrenees. Several important rivers traverse the area and have eroded the surrounding rocks leaving it with beautiful karstic formations that include dolines, caves, pits and spectacular canyons. Due to its location in between the Pyrenees and the Ebro valley, the area gets both weather systems from the Atlantic and the Mediterranean. The Guara Sierra and Canyons form a spot between two climates which marks the different vegetation: dry to the south and luxuriant to the north.

The park is located to the south of the Ordesa and Monte Perdido National Park and to the south west of the Posets-Maladeta Natural Park.

There are some trails in the Sierra y Cañones de Guara Natural Park, although not well marked. A good map and compass is recommended.

The sport of canyoning is also very popular here – the Rio Vero is a popular track and is used by many thousands of people because it is easy and requires only a walk and swim, without a rope and harness.


The village has examples of rock art at the Vero River Cultural Park. It also has a castle and the Santa María la Mayor collegiate church (the region's most visited monument) with its cloister of Romanesque capitals and its organ, along with many shrines.

Human activity can be traced back to the Upper Palaeolithic period, there are cave paintings still in existence in the shelter of Fuente del Trucho.

The mountains are traversed by four main rivers: the Flumen, the Guatizalema, the Alcanadre and the Vero, all of which leave peculiar geological formations in their wake, such as dolines, caves, pits and spectacular canyons. These canyons are the most well known feature of the Sierra de Guara.

The Griffon vulture, bearded vulture and the golden eagle are just some of the birds to be found in this area.

The Sierra y Cañones de Guara Natural Park includes Mediterranean forest, with some enclaves of Atlantic forest and mountain pastures.
