Trail 4- Selva de Oza
Near the bridge across the River Aragón Subordán is a path that climbs up to meet the old Roman road leading down from the Palo mountain pass. Shorty afterwards, the train enables us to climb up the Espata gorge and walk through lovely shady woodland amongst fir, beech and Scots pine, accompanied by mountain ash, hawthorn, yew or willow. Soon afeter, we pick up a woodland trail on our left which goes round the Ramiro el Monje camp to bring us back to the place where we started via the Netera gorge inmmersed in the atmosphere created by these wet forests stretching down the mountainside of Castillo de Acher. Along the way various species can be seen, including Great Spotted Woodpecker, Chaffinch, Common Bullfinch, Tawny Owl, Blue Tit, Marsh Tit, Black Woodpecker, Eurasian Nuthatch, European Pied Flycatcher, Common Firecrest, European Robin and Eurasian Jay.
