The Sabinares del Arlanza-La Yecla Natural Park Nature · Santo Domingo de Silos, Sierra de la Demanda, Burgos Image of Santo Domingo de Silos, not of the place itself. Created on 14 December 2020, it protects 39,173 hectares spread across twenty-one municipalities. Around a hundred pairs of griffon vulture nest on its cliffs, along with Egyptian vulture, golden eagle and peregrine falcon. The park, close to the Cañón del Río Lobos park, takes its second name from the La Yecla gorge, a narrow ravine cut by the arroyo del Cauce through the limestone of the Peñas de Cervera, today crossed by bridges and hanging walkways. Its limestone slopes support extensive stands of Spanish juniper, with specimens over 2,000 years old, alongside holm oak, Portuguese oak, and forests of Scots pine, black pine and maritime pine.
