Did you know that... The Natural Park of the Western Valleys

 

With its more than 27,000 hectares, it extends along the headwaters of the rivers Veral, Aragón Subordán, Osia, Estarrún and Lubierre and is located in the northwestern corner of the Aragonese Pyrenees. It is a natural border with France to the north and Navarre to the west. It is part of the region of La Jacetania and includes the municipalities of Aísa, Ansó, Aragüés del Puerto, Borau and Valle de Hecho, so we have a large number of places to see and things to do in the Natural Park of the Western Valleys.

What to visit in the Natural Park of the Western Valleys

The action of the glaciers modeled its relief excavating cirques, U-shaped valleys and beautiful mountain lakes known here as ibones, which are undoubtedly some of the places to visit in the Natural Park of the Western Valleys. Slender and steep mountains were also preformed, such as the Bisaurin peak with its 2670 m, the Aspe 2643 m, the emblematic Mesa de los Tres Reyes 2428 m or the Castillo de Acher 2384 m among others. The limestone rocks and their karstic modeling that occupy much of the territory have given rise to deep chasms and caves, and if the light falls on some of the characteristic red sandstones in some areas of the park, which come from materials of the Primary Era and that print a beautiful and striking reddish color, it seems that we are facing a beautiful landscape picture.

A little more history

 

The Western Valleys have seen how their territory has been populated since ancient times, numerous megalithic monuments (5000-3000 years BC) found in the headwaters of their valleys attest to this. The Romans also left their mark on the area, of which bridges and roads can still be seen, including the Roman road Caesaraugusta-Benearnum, which gave rise to the primitive Way of Santiago that entered Aragon through the Puerto del Palo. Of the mark left by the Visigoths, the monastery of San Pedro de Siresa, built over an ancient church, is another of the places we have to visit in the Natural Park of the Western Valleys. Although nothing remains of the old monastery other than the church, its size is a good indicator of its importance. In the 12th century Alfonso I granted a letter of immunity and freedom to the inhabitants of the valley, as well as privileges for the use of the mountains and pastures. The Western Valleys also saw part of the childhood of Alfonso I the Battler, first King of Aragon.
