Trail 3: Riglos
This stage includes several trails bordering the overwhelming and vertical walls of Mallos de Riglos. On Camino del Cielo we will enjoy a spectacular viewpoint, not suitable for people suffering from vertigo. We'll also be able to observe one of the largest colonies of griffon vulture in Europe.
Las Peñas de Riglos is a Spanish municipality belonging to Hoya de Huesca region. It is formed by the merge of several villages and its capital is in Riglos.
The town of Riglos is located at the foot of the so-called Outer Sierras of the Pyrenees. It is located between Santo Domingo (West) and Loarre (East) sierras, both divided by Gállego River Valley.

RELEVANT FLORA SPECIES
Riglos is located between the biogeographic alpine and Mediterranean regions, a situation that makes of this area the north limit of southern Mediterranean species and the southern limit of northen Pyrenean/alpine species. It features an extraordinary variety of flora species, especially those associated with unique geological formations such as cliffs and gorges.
Among the rupicola flora stands out: Petrocoptis montserratii, Jasonia glutinosa, Sedum sediforme, Silene saxifraga, Ramonda miconi, Saxifraga longifolia, etc.
Erodium gaussenianum (pre-Pyrenean endemism - Sensitive to the alteration of its habitat) and Petrocoptis montserratii (pre-Pyrenean endemism - Vulnerable) stands out as threatened flora.
After the creation of the Pyrenees during the Alpine orogeny, this great mountain range begins to be modeled by fluvial erosion (in this case by Gállego river), which drags the materials from the great peaks depositing them in enormous cones of dejection at the foot of the mountain range. This action creates Mallos de Riglos on the left bank of the river and Mallos de Agüero on the right bank of it.
The weather and fluvial erosion together with other climatic factors such as air, sun and temperature contrasts - among others - opened deep ravines widening fissures and forming characteristic chimneys in the area.
