Mount of encina y riberas del Eria Nature · San Esteban de Nogales, La Bañeza, León Image of San Esteban de Nogales, not of the place itself. The district alternates scrubland of holm oak, rockrose and thyme with the banks of the Eria, where broad poplar groves open out. It is a landscape of transition between the cereal moorland and the ranges that close off La Valdería to the south. Photo: Unknown author (Public domain) What to see and do in San Esteban de Nogales
