- Dehesa — open woodland of holm oak or cork oak, used as pasture.

Central Sierra Morena — Hornachuelos, Cerro del Hierro and the Hueznar
Sierra Morena is a long, worn wall between Andalusia and the meseta. It is not high. The drama is the cut of the rivers, the dehesa of holm and cork oak, and a few old mines. This central stretch runs from the Hornachuelos hills in Cordoba into the Sierra Norte de Sevilla: reservoirs, a monastery, a hole in the ground where iron was dug, and the source of the Hueznar under a tunnel of trees.
Much of the land is pasture, pine and eucalyptus plantation, or hunting estate. You come for a reservoir road, a castle town and one or two walks, not for a summit. Lynx still live in these woods; you are more likely to see deer, vultures and a golden eagle if the day is kind. Related pages: Cordoba, Seville.
*These parks are thinly served by buses. Plan the drive from Seville or Cordoba, not as a dash from the Costa.
Words you will meet
Hornachuelos and the Bembezar
Posadas, on the Guadalquivir, is the southern door. From there the park of Hornachuelos rises into dense oak and pine. The River Bembezar and its reservoir are the water of this side — willow and ash on the banks, a quiet sheet of water in the hills. Trails follow the Guadalora and climb toward viewpoints used by eagles. Some tracks cross land still used to raise fighting bulls; stay on the signed path.
San Calixto is a small monastery in the same hills, begun by hermits in the sixteenth century and now a Carmelite house. It is a pause, not a museum circuit. Las Navas de la Concepcion sits on the Seville side of the same massif, with a rocky outcrop — the Risco — and the start of the chestnut and cork country that belongs to the Sierra Norte.
Constantina and Cerro del Hierro
Constantina is the main town of this part of the Sierra Norte: a castle, chestnut walks, a place to sleep and eat. East of it, Cerro del Hierro is the oddity — an old iron mine declared a natural monument. The workings have left a maze of pale rock and cuttings. A short loop is enough. You do not need a 36-kilometre trail to understand it.
San Nicolas del Puerto and the Hueznar
San Nicolas del Puerto is the village at the source of the River Hueznar. The water comes out under a tunnel of trees and then falls in a chain of cascades. The via verde — the old railway — runs through the same valley and is the easy way to see it on foot or by bike. That combination, source, falls and level path, is the reason to come this far north.
Alanis, Guadalcanal and Cazalla
Alanis keeps a castle over the same hills. Guadalcanal is a smaller village with a viewpoint loop at La Capitana. Cazalla de la Sierra is the other town of the Sierra Norte — mills, wooded slopes, a base if Constantina is full. None of these need a checklist. Pick one if you are already on the via verde and want a roof and a plate of food.
How to reach central Sierra Morena
Seville is the natural start for Constantina, Cazalla and the Hueznar. Cordoba or Posadas is the start for Hornachuelos. From the Costa del Sol both parks are a long inland drive; sleep in Constantina or Cazalla if that is the trip.
Car hire: the flexible option
The way to reach Hornachuelos, Cerro del Hierro and the Hueznar source without depending on a thin bus timetable.
Hire a car at Malaga Airport
Taxi or private transfer
From Malaga Airport or the Costa del Sol to a hotel in Seville, Constantina or Cazalla. Stay overnight. A same-day return from the coast is a long day for little walking time.
Book a transfer*No credit-card details or advance payment are needed to request a quote. Cancellation is free. Book ahead in high season to avoid price rises and to secure the car or group size you need.
Other options
Buses from Seville reach Constantina and Cazalla. From Cordoba there are services toward Posadas and Hornachuelos. The via verde and Cerro del Hierro are easier with a car from those towns.
Practical tips
- Choose one park per day. Hornachuelos and the Hueznar are not a tidy loop.
- Cerro del Hierro is a short walk on uneven rock. Decent shoes matter more than distance.
- The via verde is the gentle option: level, shaded in parts, good if you have children or bikes.
- Autumn and spring are the comfortable months. Summer in the dehesa is hot and still.
- Stay on signed paths through estates. Some land is private hunting or bull-breeding country.
Frequently asked questions about central Sierra Morena
What is Cerro del Hierro?
An old iron mine in the Sierra Norte de Sevilla. The cuttings and rock walls are now a short walking circuit and a natural monument.
Where does the Hueznar start?
At San Nicolas del Puerto, under a cover of trees. The cascades and the old railway path are in the same valley.
Will I see a lynx?
Unlikely. They live in these hills, but they keep to cover. Look for deer, vultures and, with luck, an eagle.
Is this close to Malaga?
No. It sits north of Seville and west of Cordoba. Use those cities as the base, or allow a long drive and a night in Constantina.
What is a via verde?
A disused railway opened as a path. The Sierra Norte via verde is level and suitable for walking or cycling.
Do I need a car?
A bus will get you to Constantina or Cazalla. A car is how you add Hornachuelos, the mine and the river source in one trip.
