The central section of the immense Sierra Morena is made up of the extensive and sparsely populated Sierra Norte de Sevilla Natural Park, a landscape of gently rolling hills clad in dense evergreen oaks. It's similar to the adjacent natural parks of the Sierra de Aracena y Picos de Aroche and Hornachuelos, in the provinces of Huelva and Cordoba respectively.

Alanís is set within the Comarca Sierra Norte of the Seville province, north of Cazalla de la Sierra. Only several kilometres from the border of Andalusia to Extremadura, it has about 1850 inhabitants.
