The Montes Obarenes
Bordered on the north by the Ebro river, the park includes river canyons, ravines, gorges, synclines and the Obarenes mountains themselves. The main highlights of the park are the ravines carved out by the Ebro river in Sobr├│n and the gorge created by the Oca river near O├▒a. Many different birds of prey have made their nests in the numerous cliffs, especially in the Hoz de Sobr├│n. Visitors can also soak up the culture in the nearby town of O├▒a, where there is an excellent medieval monastery.
