Tastavins River Nature · Peñarroya de Tastavins, Matarraña, Teruel A watercourse that rises in the municipal district of Peñarroya de Tastavins, at the confluence of the Escalona ravine and the Escresola ravine, and gives its name to this town in Teruel province before flowing into the Matarraña. It also crosses the districts of Monroyo, Fuentespalda, Ráfales, La Portellada and Valderrobres, serving as a municipal boundary along many stretches. Owing to its torrential nature, the floods of the Tastavins are larger and more violent than those of the Matarraña itself. Along its course through Tertiary materials it has eroded the conglomerate strata, giving rise to place names such as El Tormassal, and at La Portellada it forms a waterfall known as the Salto de la Portellada. Along its banks traditionally irrigated market gardens survive, although the river's flow is not regulated. Photo: Adrian Sediles (CC BY-SA 4.0) What to see and do in Peñarroya de Tastavins
