The nature in the region of Sobrarbe is remarkable in three important aspects:

Geologic. Used by prestigious universities as an on-location school. The Sobrarbe county, due to its geological wealth, has been included by the UNESCO within the European Geopark Network.
Botanist. The different soils and habitats (alpine and Mediterranean) have fomented an abundant botanical community, unique in Europe.
Fauna. It is sanctuary for species threatened with extinction like the Bearded Vulture (Gypaetus Barbatus).
