As of 2017, observation was still permitted up there (in September). Of course, this may have changed in the meantime. Good luck!

The Mallos of the Aragonese Pre-Pyrenees were formed 65 million years ago after eroded material from the Pyrenees washed away.

Agüero's mallos are a little less tall than those of Riglos, but even so, they are charming whims of erosion. Its contrast with the blue sky on a sunny day is simply spectacular.

We are in the Pígalo pools, ideal for warm summer days where we can take a dip. If we go upstream, we will find more less crowded pools, since this one is quite popular and soon fills up with people. If we want to leave the car in the car park, we must book on the Luesia town hall website as they control access. There are picnic areas to eat and a bar at the campsite.

Frequently Asked Questions

What are the most prominent natural monuments to visit in Las Peñas De Riglos?

The most prominent natural monuments are the towering Peñas de Riglos, which shelter the town of Riglos itself. These massive conglomerate rock formations are renowned for their dramatic appearance and are a world-class destination for climbers. Another must-see are the Mallos de Agüero, spectacular reddish-colored rock formations that also offer excellent climbing and bird-watching opportunities.

What kind of geological formations can I expect to see in Las Peñas De Riglos?

Las Peñas De Riglos is famous for its striking geological formations known as 'Mallos'. These are massive, reddish-hued conglomerate rock towers, rising dramatically up to 300 meters from the ground. They were formed over millions of years from eroded material from the Pyrenees, cemented together and then shaped by erosion, leaving behind these resistant, vertical structures. The reddish color is due to their iron content.

Are there opportunities for bird-watching, especially raptors, in the area?

Yes, the area is a Special Protection Area for Birds (ZEPA) and is exceptional for bird-watching. It hosts one of Europe's largest colonies of griffon vultures. You can observe these magnificent birds and their breeding grounds from the Riglos Griffon Vulture Viewing Area. Other raptors like Egyptian vultures, peregrine falcons, and bearded vultures are also present.

What hiking opportunities are available around the natural monuments?

Beyond climbing, the area offers numerous well-marked hiking trails with breathtaking views. A popular option is the 'Vuelta a los Mallos de Riglos', a circular route starting from Riglos village. The 'Camino del Cielo' is another highly recommended circular trail. For more detailed routes, you can explore the MTB Trails around Las Peñas De Riglos guide, which also includes hiking paths.

Are there any family-friendly activities or natural monuments suitable for children?

Yes, the Pígalo Pools are ideal for families, especially on warm summer days, offering natural pools for swimming. While popular, you can find less crowded spots further upstream.
