This nature park is situated in the Central Sierra, in the provinces of Segovia and Ávila. The landscape is dominated by a vast mountainous ridge and dense forests of Scots pines that cover the slopes, whilst the lower areas are clad with oaks, holm oaks and junipers.

This space is the habitat for an outstanding range of fauna, including some of the Iberian Peninsula’s most emblematic species such as the Spanish imperial eagle, the black vulture and the black stork. The area boasts a perfect state of conservation and is well worth a visit.
