The Iberian range seems to want to reach out to the Mediterranean via the Espina and Espadán sierras, separating the Mijares and Palancia river basins. The Espina sierra is crowned by mount Santa Bárbara de Pina (1,405m) sheltering valuable vegetation on its skirts. In the Espadán sierra, a unique combination of Triassic sandstone soil and copious rainfall maintains magnificent pine tree and cork oak forests. The villages of Aín, Almedíjar, Eslida, and Villamalur - among others - provide access to the Sierra de Espadán Nature Park, with its network of signposted hiking routes: the GR-36 and a number of Short-Distance Hiking Routes. Around the festivity of San Juan (24 June) the extraction of cork from the cork oaks enlivens the local scenery, with the usually dark tree trunks turning bright red in a magic contrast of chromatics.
