Within the Serrania we are lucky enough to have three natural parks, Grazalema, Sierra de las Nieves, and Alcornacales, and at El Bosque, a small botanical garden “El Castillejo” devoted exclusively to the local and endemic plant species of these mountains.
Due to the Serrania being both Mediterranean and European, many of the tree species are common throughout Europe, whilst most of the shrubs are generally Mediterranean. Most of the flowers and grasses are either Mediterranean or endemic to the area. Your stroll will take you through several mini ecosystems, each with their own viewing area to sit and appreciate the surroundings.
Sadly many of the endemic species of the area are endangered, and not just in the Serrania, so the botanical gardens now also have preservation areas set aside for plants from the Sierra de Loja and Sierra Bermeja, thus ensuring that qualified botanists are able to track grwoth patterns and grow new seedlings for transplant should this ever be required.
As you wander around pay attention to the signs next to each species, a red dot in the top left corner indicates the species is in danger of extinction, while a yellow dot indicates the species is vulnerable. An orange dot signifies a species that is endemic or peculiar for some reason.
The park has adequate parking, and toilet facilities at the main entrance, which is also where the library and classrooms are located. Take care not to hurt any wildlife you encounter, from insects to lizards and snakes, all of which are a vital part of the ecosystem.
