Don't miss these unique wonders in Europe. In Aragon these unique reddish geological formations characteristic of the Hoya de Huesca are called 'mallos’ (mallets).

Legend has it that King Pedro I left the mallets of Riglos as an inheritance to his wife Doña Berta, since it was the only landscape that could be compared to her beauty.

And it is true that the mallets of Riglos, with their enormous vertical walls that rise more than 300 m above the waters of the Gallego river, on the natural border between the Pyrenees and the Ebro valley, leave no one indifferent.

The Riglos are the most famous, but in this same area you will find the mallets of Agüero, Vadiello, Murillo de Gállego and the Salto de Roldán, among others. We recommend that you visit them at sunset, when their reddish colour is accentuated and contemplating them is even more spectacular.
