Peñarroya, Mountain summit in Sierra de Gúdar, Spain

Peñarroya is a mountain summit in the Sierra de Gúdar reaching 2028 meters above sea level with a rounded peak in Spain's Teruel province. Dense pine forests cloak the slopes of this peak within the wider Sistema Ibérico mountain range.

Peñarroya is a residual limestone and Cretaceous sandstone hill that rises barely above the erosion surface of the Sierra de Gúdar. Its position and lithology left it shaped by Quaternary karstic and periglacial processes. At 2028.228 m it is the highest point of the Teruel part of the Sistema Ibérico, in the municipality of Alcalá de la Selva.

The summit's name, Peñarroya, comes from the Spanish peña (rock) and roya (rust-coloured), referring to the reddish limestone and sandstone of the Cretaceous residual hill. The peak marks the highest point of the Teruel part of the Sistema Ibérico, a fact known to walkers who use the geodesic pillar as a landmark.

Two main trailheads give access to the summit at Collado Gitana and Alcalá de la Selva, with parking available at each location. The mountain is most accessible during warmer months when weather conditions allow safe passage on the paths.

The summit's most distinctive feature is a geodesic vertex about 10 metres tall, which can be climbed. From the top, the Maestrazgo and the Sierra de Javalambre come into view. The peak is a residual hill of Cretaceous limestone and sandstone rising barely above the erosion surface of the Sierra de Gúdar.
