Montes Obarenes Natural Park
Discover the Montes Obarenes, the last foothills of the Cantabrian Mountains that rise like a natural wall over the plains of La Bureba. Explore gorges, ravines carved by rivers such as the Ebro, the Oca and the Purón in the Sierra de Arcena.
Marvel at the biodiversity: wild cats, otters, wild boars, roe deer and endangered species such as the European mink and the bearded vulture. Observe the varied flora with beech trees, holm oaks, holly, juniper, boxwood, oaks and pines, thanks to the mix of Atlantic and Mediterranean climates.
Immerse yourself in cultural heritage with the medieval monastery of San Salvador in Oña and the Church of San Juan Bautista. Visit picturesque villages such as Frías, the smallest town in Spain, known for its castle, fortified bridge and hanging houses over the Ebro.
