Located in the southwest part of Malaga province, the Sierra Bermeja is a mountain range with an average height of 1,000m (its highest point being 1,450m), covering 1,236ha. It is an area that has undergone major volcanic activity; the rocks are rich in the olivine mineral. Rainwater has oxidised the iron and magnesium present in the rocks and the iron oxide has coloured the rock reddish-ginger, a hue that gives the sierra its name.
