Once an altozane is reached, the panorama opens and an era serves as an unconventional lookout. Shortly after and already practically horizontal, the lane draws a recess next to the abrevadero of a semi-noise cortijo.

After the ruins, the pecuary road is diverted by a less obvious road that goes back a small uncamped ravine. When you reach the highest area you have to turn back, now to the left and on the path that borders the olive tree. A short time later, he will be in a lane that will go to a crossing.

The road on the left is fork right away. The left branch will be where it returns and the other one goes down in the direction of the Cortijo de Nogueruelas. After passing through the buildings, it goes back up to a hill where another cortijo is located.

At this point you must cross the access gate to a cherry plantation, and leave two lanes to the left. Shortly before the olive tree starts a path that goes up to the hill, just at the foot of Cerro La Martina and the breakers where the route ends.

To return, it descends on the same path to the first cortijo, for this time to take the lane on the right that runs on half a hillside.

Some tractor rounds arise to the right and left and are introduced into the agricultural farms, but the lane offers no doubt. The olive trees cover almost the entire slope and will accompany us along the climb. At 20 minutes' walk, right on a very closed curve, a crossing appears. In this case you will choose the way on the right that goes up with a strong slope. 10 minutes later a less obvious lane will be left.

The road then approaches the rocky pharallions and, shortly before reaching the top, it forges. The left branch reaches the edge of the calcareous wall and in a few minutes, the Cave of the Contadero is now transformed into a small serrano sanctuary.

From this point, the route follows the path that runs along the same edge of the slope. After framing a fence of wires is introduced into the rough flat calcareous area. First the naked and sharp rock makes it difficult to march and then the bushes. Despite these drawbacks, in 35 minutes the edge of the impressive cuts of La Veleta is reached. The improvised lookout is not suitable for those suffering from vertigo. At this point extreme precautions if the route is done with children or dogs. There is a risk of vacuum falls.

Not far from the road and just in front of the cortijo, it starts on the right a signposted path parallel to the stream, which later must be watered shortly before the wire. Once on the other side, the explanade is crossed in search of a path that penetrates the beautiful throat of the Arroyo de la Fresnedilla.

The ravine gradually narrows and forces several times to change the shore. At the confluence with another stream and after walking about 25 minutes, the ravine opens. At this point you have to move to the right margin to link with a dirt lane. The road now accompanies the rising river bed, on some occasions on the right bank and on others, on the opposite. Unavoidably, you have to go through the channel several times, and if it has a lot of water, you will even have to go down on more than one occasion.

Finally, the lane disappears. The route continues to jump from one bank to another in search of the most comfortable steps to a dam and waterfall, after an hour and ten minutes.

It is taken on the right bank, the sidewalk of the acequia that used to carry the water from the chorreta to the old light factory, in the Barranco de Valdearazo. Place where the route ends.

The first meters of the walk are already on the platform of the Via Verde del Eil until its confluence with the autonomous road. The road is passed with great caution - although there is good visibility, cars are moving at high speed - to link with the old railway route. From here, the dilated olive countryside is almost in a straight line.

After walking about 25 minutes, you reach the first lagoon, the Nature Reserve of the Honda Lagoon. The water sheet is surrounded by an eneas and carrizos that provide shelter, during the winter, to a multitude of aquatic birds. The best way to appreciate the lagoon and the avifauna is from the same railway platform. Getting close to the water sheet means losing perspective.

The route continues a mile along the road. When he reached a raft, he moved along the lane that went up to the right. A little later it passes by the Cortijo del Chinche, from where the second lagoon, the Natural Reserve of the Laguna del Chinche, is already seen. Although smaller than the previous one, it also houses a large group of anatids. The most suitable point for contemplating it is from the left-hand lane at the next crossing. The latter section is not suitable for users with reduced mobility.

To return to the starting point, we will use the same route. If desired you can extend the walk to the end of the Green Way of Oil and the province of Jaén, near the Embalse de Vado Mojón. There it links with the Via Verde of the Subbetics, already in the province of Córdoba.

As soon as you have started to climb, the Pancorbo Residence lane is left to the right. The height gained by a few reels, already allows to enjoy the panoramic views above all the Barranco del Río fría, under the coat of the Sierra de La Pandera. In the autumn, when the colors become toasted, the place acquires quite spectacular tones.

At 50 minutes a crossing is reached: we must continue to climb to the right. Later on, a side lane is left, also to the right. Then the slope soften. After a cortijo, the lane ends in a depression, after an hour and a half of marching. At this point it is necessary to turn left, on a narrow signposted path that leads in 15 more minutes to the Port of the Hoya.

On the other side a lush pine covers the slopes. The path that encourages you to discover the forest, starts from the same hill and soon links with a forest track. Later on, it comes into a crossing: to the left, and in ten minutes, you reach the forest house of the Hoya del Caño.

This point presents the alternative of going up to the port of the Navy and linking with the route that descends to the Port of the Coberteras on the side of Valdepeñas de Jaén. In front of the ruins continues a path that first descends to a stream and crosses it. It is soon transformed into a sidewalk that zigzaguea way to the port.

On the same roof, two lanes are born, the one on the left side ends in a few meters in the New Cortijo. Right behind a waterfront begins the path of the Port of the Navy. The first section of the climb runs under the vertical flannel of the saw of La Pandera, through a rugged forest of sparrows and Mediterranean bushes.

Later on, the trees give way to a pallet and thorny vegetation. The height gained already allows you to enjoy splendid panoramic views over the Quebrajano Embalse and the surrounding mountains. Then the path is transformed into a beautiful steep sidewalk that is twisted by the abrupt and rough hillside. It straps three sticks of wires that limit pastures and municipalities. Finally, the sidewalk reaches an altozane where it ends abruptly after 50 minutes of march.

The aggressiveness of the land is lost in this herbous raid presided by a corpulent oak; it is the ideal point to delight with the panoramic views, now much more dilated.

To complete the route it is possible to approach the same Port of La Nava in about 20 minutes. First, it is necessary to descend to the bottom of a garden, where an abrevadero is located. Then it rises through a forest of pine trees intermingled with some other year old oak, until it finds the highest point of a calvero.

The entire route has been divided into 28 linear stages and one circular alternative route in the province of Seville. All of them can be comfortably completed during a single day of hiking. Each stage begins and ends either in one of the municipalities through which the trail passes or in places where food and overnight accommodation are available, such as the Sanctuary of the Virgen de la Cabeza in the Sierra de Andújar.

In the province of Jaén, the GR 48 is divided into five stages. Some of these are among the longest in the whole of Sierra Morena and, without detracting from the routes through the other three provinces, they are among the most highly appreciated by hikers because of their exceptional beauty.

The Jaén section of the GR 48 is characterised by its varied landscapes. Along the route, the typical wooded pastureland of Sierra Morena, where livestock graze, alternates with the steep slopes of the Sierra de Andújar and the foothills of Despeñaperros. Here, gorges, ravines and medium-altitude mountains create an evocative landscape reminiscent of high-mountain regions.

The Sierra Morena trail in Jaén is divided into five stages, taking us from Marmolejo to the centre of Santa Elena. Along the way, the route passes close to important landmarks such as the Sanctuary of the Virgen de la Cabeza, the outstanding historical heritage of Baños de la Encina and the former mining pasturelands around La Carolina. The journey crosses constantly changing landscapes in which Mediterranean woodland blends with more rugged natural surroundings, creating spectacular scenery whose colours vary throughout the year and are at their finest in autumn and spring.

However, this route offers much more than scenery. The absence of major towns in the heart of the mountains has allowed the area to remain exceptionally well preserved, making it relatively easy to observe birds and mammals at almost any point along the GR 48.

The great biodiversity of this territory provides an opportunity to observe unique species of both fauna and flora. The Sierra de Andújar is one of the last remaining strongholds of the Iberian lynx, as well as being home to other protected species such as the cinereous vulture and the golden eagle. As this area is one of the most important hunting regions in Spain, sightings of large mammals such as red deer, fallow deer and wild boar are very frequent and almost commonplace. Extensive cattle-grazing estates with herds of fighting bulls are another attraction, becoming more common as the trail continues towards the north-east of the province, particularly along the central section between the Sierra de Andújar Natural Park and the Despeñaperros Natural Park.

In addition to the species already mentioned, those interested in herpetology will find a significant amphibian population along the Jaén section of the GR 48. This includes species found exclusively on the Iberian Peninsula, such as the Iberian painted frog, the Iberian newt and the Iberian midwife toad.

The vegetation encountered along the route consists mainly of typical Mediterranean woodland and scrub, dominated by holm oak forests with rockroses, mastic trees and wild olive trees. These are complemented by examples of the conifer plantations established in the mid-20th century, particularly the pine forests around the Sierra de Andújar and near Santa Elena in Despeñaperros. Along the streams and rivers crossed by the GR 48, hikers can also appreciate riverside woodland, such as that found along Los Santos Stream during the first stage, the Jándula River during the second and the Campana River during the final stage.

When walking the GR 48, it should be remembered that the stages cover long distances and are best completed over full days. Food and supplies are available at the beginning and end of each stage. Nevertheless, particularly on the longer stages, it is advisable to carry plenty of water, as Sierra Morena is typically dry and there are few springs where hikers can quench their thirst. The time of year should also be considered carefully, as summers in Sierra Morena are extremely hot, with very high temperatures during the summer months. Anyone wishing to complete the trail during July or August should therefore plan their schedule carefully and alternate periods of walking with adequate rest.

In addition to the sensory pleasure of walking along this trail, each stage leads to fascinating places that reveal the rich heritage left in the province by different civilisations. Throughout the route, there are numerous reasons to make short detours and explore the past: archaeological sites and prehistoric cave paintings provide a connection with ancient history; the magnificent medieval heritage of Baños de la Encina and the nearby battlefield of the Battle of Las Navas de Tolosa in Santa Elena recall the Middle Ages; while the elegant urban layouts of the New Settlements of Sierra Morena and the surrounding mining remains provide evidence of the province’s more recent history.

After passing through an alpechenera and under an old bridge of the mining railway the path ascends along the stony coast of San Pedro to the Cañada de Incosa; from which we continue, to the right, a stretch that presents, to the west, magnificent views of the population of Baños de la Encina.

Walking this path is moving in memory to a period in the history of Linares.

After 1.4 Km we connect with the road and by a wooden step we take the Green Way until we reach a crossing (connection to the path of the Gitana Mine PR-A 264), then we pass through the solid waste treatment plant and continue on the old steep path of Siles that will lead us back to Linares.

The itinerary turns left and gently descends between chaps, next to air-navigation antennas, enjoying beautiful panoramic views. It concludes the fall at a crossroads between the Cerro de las Manciebas and Pico, near the Dark Porvenir well. We continue on the right to reach the hill, connecting with the path of the Garza, PR-A 262. Let us go on a path that will make us drunk by its beauty and by the history of its mining remains: the Pozo Zulueta, the Pozo de San Ignacio and the Lavadero de Mineral de Arrayanes, as well as views of the valley of the lagoons.

In the Lavadero de Arrayanes (construction on the hillside to take advantage of a gravity circuit that separated the mineral, through several phases) we moved away from the path of La Garza to continue a ramp to reach the well of San José and the Central Electric, where the route coincides again with the path of Pico to the well restoration, in which they are separated following the Green Way.

About 100 meters from this point the Via Verde is bifurca (1); on the left you reach the La Cruz Fundition road, which we follow 20 meters to take a lane to the left, next to a ruins, which leads to an aerodrome. We find two branches outside the path, both on the left, interesting if time is available, the first leads to the well Chaves and the second to the High Alamillo Mine with the possibility of enjoying an unbeatable view. Later there is the urbanization of La Cruz, where we will reach the beginning of this mining route.

(1) This bifurcation on the Green Way on the right is a shortcut to the La Cruz Fundition when little time is available to make the route marked

In the well restoration, open between 1844 and 1850, the building that housed the garage and locomotives workshop of the mining railway stands out. In the well of San José, next to the road, you can still see the place called "Bajada de la Reina," made for a visit by Elizabeth II to the first gallery.

We pass by the well Cadenas and later through the Vimora Lavadero, example of natural regeneration of the vegetation of the area...

The path continues to Paño Pico (geodetic vertex) and the Mina de La Mexicana, don enclaves from where it is possible to enjoy an unbeatable panorama of the area: far away La Carolina and Baños de la Encina, closer to the Hoyo de San Bartolomé, Cerro de las Manciebas, etc. From Mexico an ancient road between oak trees, interrupted by an olive grove, leads to the Fireplace de la Cruz, one of the highest in the area that reached a height of 100 m (today it is 57 m), and where the path reshares route with the PR-A 261. We passed by the Pozo Cadenas and later on through the Vimora Lavadero, an example of natural regeneration of the vegetation of the area, to go around the urbanization until the end of the La Cruz Foundry, where all types of lead products were made, and that will be the seat of the future Interpretation Centre.
