The Esparteros mountain range, catalogued in the Special Plan for the Protection of the Physical Environment of the Province of Seville as a Mountain Complex of Environmental Interest, is located to the south-west of the town of Morón de la Frontera. It is very close to the villages of Aldea Guadaíra and Caleras de la Sierra.
The Sierra de Montellano, also known as the Sierra de San Pablo, on whose slopes the town is located, is a limestone formation that reaches an altitude of up to 600 m, and which preserves natural vegetation of great interest for a town whose surrounding area is occupied largely by arable crops and olive groves.
The Sierra de la Jayona, in the municipality of Guadalcanal belonging to the Sierra Norte Natural Park, is made up of shales and Cambrian limestone, folded during the Hercynian orogeny, with a northwest-southeast direction like its neighbour Sierra del Viento, from which it is separated by a deep valley.
Like the Sierra de Becerrero, this mountainous area next to the town of Gilena belongs to the Sub-Baetic Zone, one of the outlying areas of the Baetic Mountains, and is made up of marl and limestone. The highest point in the sierra is the Acebuchosa peak, at 663 m.
The Sierra de Becerrero massif, also called Sierra de Estepa, has been declared a Mountain Area of Environmental Interest, and is located between the towns of Estepa, Gilena, Pedrera and Lora de Estepa, rising sharply from a fairly flat environment.
The Sierra del Pimpollar and the Sierra Padrona, are two granite formations located one after the other. The orientation of the structures is northwest-southeast, as is the case throughout the Sierra Norte. Their altitudes are among the highest in the Natural Park at around 900 m.
The Sierra del Viento, in the western part of the municipality of Guadalcanal, has the highest peak in the Sierra Norte Natural Park of Seville. It is La Capitana, with an altitude of 960 m, whose viewpoint offers spectacular views of the northern part of the Natural Park, including both other nearby mountain ranges and the plains of Guadalcanal and the peneplain of Extremadura.
