The park acts as a natural corridor connecting the Iberian System mountains with the Duero river basin.
Parque Natural Cañón del Río Lobos is a limestone canyon carved by the Ucero River located in the provinces of Soria and Burgos. The park features high vertical cliffs reaching up to 100 meters, characterized by karst formations including sinkholes, caves, and arches. Dense savin juniper forests cover the canyon floor, providing a habitat for a significant population of griffon vultures. The San Bartolomé Hermitage, a 13th-century Templar-influenced structure, is situated centrally within the canyon. Visitors can traverse the park via a 25-kilometer longitudinal trail connecting the Ucero and Hontoria del Pinar entrances. The terrain is part of a wider Special Protection Area for Birds, hosting endangered raptors like the Egyptian vulture and golden eagle.
