Straddling the extensive pine forests of northern Soriano and the fertile plain of the Duero that runs through the south of the province, a unique space opens up, a gap in the rocks that stages a landscape of vertical cuts of living rock that frame juniper and juniper forests. black pines watched from the air by griffon vultures, eagles and falcons.

The Lobos River Canyon, which is accessed under the watchful image of the Ucero Castle, is peacefully traversed along both sides of the river bed adorned with water lilies until reaching the magical setting presided over by the Templar hermitage of San Bartolomé from the 13th century. Behind it opens the enormous entrance to the cave, inside which prehistoric engravings are preserved.
