The Reales de Sierra Bermeja Natural Site is a natural space split between the municipalities of Casares, Genaguacil and Estepona. Covering a total of 1,236 hectares, it makes up part of the Sierra Bermeja range and separates Serranía de Ronda from the Mediterranean coast. In addition to the wealth of cultural and tourist interest to be found in these municipalities, the site has flora and fauna which are unique in Andalusia: a walk around the interior of the Sierra is full of special landscapes, as shown by the presence of peridotites, a volcanic rock which has remained in the region with the passage of time and gives it a unique character. This mineral richness and the characteristic rainfall in the area give it a unique range of plant species, such as Galium viridiflorum and Slaelina baetica, both of which can only be seen in this region. There is also an area where Spanish firs can be seen growing on peridotites. The species dates back to the Ice Age and has remained among the area’s tree species, along with the pine and the cork oak. This rich vegetation also provides a habitat for large mammals, such as the roe deer and the Spanish ibex, as well as other species such as the common genet and the Egyptian mongoose. The golden eagle and Bonelli’s eagle can also be seen flying over the site.
