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.
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.
The Sierra del Agua is located in the north of the Sierra Norte Natural Park and, together with the Sierra del Viento, has the highest peaks in the Sierra Norte. The relief of the Sierra del Agua is also very rugged, with steep slopes of up to 70%.
In the heart of the Sierra Norte Natural Park we find the Portuguese Oak Grove of La Vejera. It is located to the south of Cerro del Hierro, in an lightly sloping area. It is formed by a group of large Portuguese oaks that form a line along a 1 km stretch of a cattle track as it passes through Constantina, the path from San Nicolás del Puerto to Navas de la Concepción.
The Venta de Las Navas ZEC belongs to the Guadalquivir sub-basin between Retortillo and Huesna. Geologically, it is characterised by the fact that it runs among hills over metamorphic rocks. The area is mainly included in the mountain range landscape category, within the low mountain range sub-category.
We leave Almadén de la Plata on the A5301 road to Real de la Jara. After 11km we will find a turn-off to the right towards Cazalla de la Sierra, on the SE179 road. After 9.5 km we will crown the Puerto Padrona- Puerto Quejigo and 17 km later we will arrive at the village of El Pintado, from where there will be 15 km left to finish the stage until we reach Cazalla de la Sierra.
We leave Ronquillo on the N630, driving approximately 4.5 km to the turn-off to Almadén de la Plata, on the A8175 road. We will travel 8.5 km until we reach a crossroads where we will have to continue on the left, always towards Almadén de la Plata, along the same A8175, for 9 km, until we reach Almadén. In this stage we will enter the Sierra Norte Natural Park.
