These great vertical walls are spectacular to see and could not be better for climbing. Their rounded shape is formed by rocks or conglomerate formations, known here as “MALLOS”, typical of La Hoya de Huesca.
As you may already have seen in the attractive pictures, some of them are reddish in colour caused by the iron minerals they contain. This colouring is accentuated at sunset.
A visit to the Mallos of Riglos, Vadiello and Agüero, and also to the Salto de Roldán, is ideal for watching birds of prey, for enjoying nature in a perfect state of conservation, for climbing and for relaxing your eyes with this unique panorama.
