Description

Los Mallos de Riglos are conglomerate rock formations rising up to 300 meters high alongside the Gállego River in Huesca province, Aragón. These vertical walls stand out in the Pre-Pyrenees landscape and are a benchmark for sport and traditional climbing in Spain.

When visiting Los Mallos de Riglos, you'll see a series of large monoliths jutting from the ground, with rounded and vertical shapes. The local biodiversity includes birds of prey such as the griffon vulture, which nests on these cliffs. The natural surroundings offer hiking trails with panoramic views of the valley and river.

These formations originated millions of years ago through sedimentation and compaction of materials in an ancient riverbed, followed by erosive processes that shaped their current structure. Los Mallos have been a reference point for locals and climbers since the mid-20th century, contributing to the development of mountain tourism in the area.

Access to Los Mallos de Riglos typically starts from the village of Riglos. The visit is free and requires no prior reservation.
