Situated in the north of the state of Andaulcia, Sierra de Andujar has a landscape of rolling hills, dotted with rounded rocky outcrops of granite and an extensive Mediterranean forest known as dehesa. The 74,774-hectare park protects one of the best preserved areas of holm and cork oak forest and Mediterranean scrub comprised of strawberry trees, myrtle and wild olive in the province. Fauna includes one of the largest populations of Iberian lynx in the country: around 80 individuals are thought to live within the park and, although elusive, can be spotted with patience and luck.
Red and fallow deer, wild boar, rabbit and Iberian hare are among the more commonly seen mammals, with otters sometimes seen along the Jándula River and Spanish ibex at the Jándula dam.
Birdlife is plentiful with birds of prey a particular highlight: both golden and the endangered Spanish imperial eagle nest in the park and the enormous black (cinerous) vulture can often be spotted on thermals. The Iberian azure-winged magpie is a local speciality that is particularly common here and other birdlife includes little and eagle owls, golden oriole, black wheatear, blue rock thrush, rock bunting, hawfinch and crag martin. Reptiles include a population of Spanish terrapins and viperine snakes along the Jándula River, and the large, colourful ocellated lizard and moorish gecko are widespread.
