The canyon route to San Bartolomé Activity · Ucero, Tierras del Burgo, Soria Image of Ucero, not of the place itself. The park's classic itinerary runs along the bottom of the gorge from the Puente de los Siete Ojos to the hermitage, among rock walls, junipers and pools. It is a flat, long path, much walked in spring and autumn. Photo: Rowanwindwhistler (CC BY-SA 3.0) What to see and do in Ucero
