The Algairén Sierra is a mountain range located in the Cariñena Countryside (Zaragoza, Aragón). It is a small individual part of the IberianSystem, extending from Alpartir to Encinacorba, and running alongside the Ebrodepression, through Almonacid de la Sierra, Tobed, Cosuenda, Codos, Aguaron, Encinacorba, Santa Cruz de Crio and Mainar.

It bears northwest to southeast, parallel to the Ebro valley. Its northwestern side is fragmented into two branches by the Alpartir gully, lodged in a seismic fault line that dies out towards the South.

The Sierra is made of Cambrian slate and quartzite raised during the Alpine folding between two large fissures, which descend from the mountains to the Grío river valley and to Cariñena fields. In the South lies the town of Tobed, where you can make a comfortable ascent to the peak of the mountain range,Valdemadera Peak, 4,186 feet above sea level.

The Algairén Sierra is classified as SPAs (Special Protection Area) for birds, within the declaration of the Natura 2000 ecologicalnetwork. The flora of the mountain is composed of rosemary, rockroses, junipers, and even cork-oaks, a rare specimen in Aragon, as well as reforested pines like Pinusnigr, Pinuspinaster and Pinushalepensis.
