The canyon of the Guadalanimín River is a river form generated by the fitting of the Guadalanimin River in the dolomies of the upper Cretaceous of the Sierra del Pozo. This river also takes advantage of a fracture of medium direction N-S. The formation of this morphology has therefore involved river, karctic and tectonic processes.

The recreational area in the initial section consists of various elements for the recreation of the users such as children's games, kiosks, fountains, barbecues, tables and benches, trees, football field, etc., making this environment a great place to spend a day in the field.

It is currently in the process of preparing and revaluing tourism under the premise of providing an intervention and rehabilitation that is environmentally friendly, with its traditional character and respecting its current physionomy.

Its landscape is an exponent of karmic modeling. No one can say that he knows the Park in depth if he has not traveled the overwhelming plains of the Campos. The high mountain grazing is here the real protagonist; an activity that has, for centuries, allowed life in these remote territories, the homeland of the Segurean sheep.

They say that in Los Campos solitude is felt. There are no fewer people here than in the wooded areas of the Park, because it is common to find some shepherd. What happens is that the clear breadth that our eyes perceive makes us more aware of our small than in dense forest areas.

The real beginning of the Hernán Perea Campos is about 11 km from Don Domingo, after having passed the Cañada Hermosa shelter, first of the three shelters that support the mountaineers on this route. They were built by the ICONA in the 1970s and are located next to the main road, which is surrounded by light depressions, dolins and sour rocky cords of limestone origin.

The harsh weather conditions have created a very adapted vegetation of piorns, albar thorn and common juniper (rake). We will also find some sown pieces of cereal, and of course many herbaceous plants from which the livestock is fed.

If we make the way in winter, with the snow covering its unique orography, we have the feeling of crossing an Arctic landscape. We must be very well informed of the weather, because a strong snow can put us in serious trouble. Spring is the best time to visit the Campos, when conditions are less demanding, although a good advice for any time is not to abandon at any time the main road that crosses the altiplanicie from north to south.

We suggest:

• About 3.5 km from Don Domingo is the famous Pino Galapán, a 39-metre-high larix pine specimen in the area. A respectful visit to this "giant" in the Segura saw is required.

• Rapist birds fly this place majestically throughout the year. The prismatics will be of great use to you to try to distinguish the royal eagle, the leonate vulture or... maybe the broken bones? The muflons are very abundant.
  
• We must not forget that the beauty and grandiosity of the Campos is a major danger in certain times of the year. Winter, which here covers almost all autumn and part of spring, can be surprised by huge snowfalls that may eventually catch visitors, or leave them without the few visual references in the altiplanicie. In any case, in order to travel through these sites, you always have to use all-terrain vehicles, at least two cars, to provide support, as there is no telephone coverage. It is not advisable to stay in the winter months or in the twilight or night hours, and always to let third parties know that the tour begins.

From Santiago de la Espada we take the A-317 towards La Puebla de Don Fadrique. At 2.1 km, on the right, we find the JF-7091 road to La Matea. We take this road and follow it to the village of Don Domingo. The forest track towards Rambla Seca leads us to the fields of Hernán Perea.

The fields of Hernán Perea make up the most extensive altiplanicie in Spain. They have an average altitude of between 1,600 and 1,700 metres and an area of more than 5,000 hectares. This vast altiplano represents one of the largest and most original landscapes of the Natural Park Sierras de Cazorla, Segura and Las Villas, very different from all others. The harsh weather conditions have created a very adapted vegetation of piorns, albar thorn and common juniper (rake). Rapist birds fly this place majestically throughout the year. The prismatics will be of great use to us in trying to distinguish the royal eagle, the leonate vulture or... maybe the broken bones? The muflons are very abundant. About 3.5 km. From the village of Don Domingo is the famous Pino Galapán, a 39-metre-high larix pine specimen in the area. A visit to this botanical "giant" is required.

In the westernmost part of the Cazorla saw, tectonic scales of Cazorla and del Chorro, the Oxfordiense is also represented by nodular and rhythmic margoso- calcareas, by sponge and stromatolite bioconstructions, some of which perfectly retain the depository morphology, giving reliefs in the form of mounds ("mounds") made up of sponges and, most of them, of which are stromatolites. The spongiaries, siliceous sponges epigenized to calcite, appear mainly in the lower part of the bioherm, at first disorganized and fragmented and then adapted to different surfaces.

The stromatolites, on the other hand, constitute the majority of the bioconstructed body, and begin to be planar and then move to centrimetric columnar forms that together give cupolas of almost half a metre in diameter. Some of these depository morphologies can be observed on the slope of the road that from Cazorla leads to the Chorro, where this point of geological interest is located. These deposits culminate the depository sequence of the Oxfordiense in the saw of Cazorla, which is a sequence of deepening, in response to the oxfordiense transgression that caused the disappearance of the platform of the Lïas-Dogger, whose deposits are crowned by a "hardground" on which the Oxfordiense sequence is available. This sequence, in turn, is overtaken by another of lower Kimmeridgian age with which again the somerization that will culminate the Jurassic cycle begins.

Access route: By mountain sidewalk.

A road to the right is about 400 metres from the forest house of the source of Steel that will take us to the top of the Guadaltiín River.

From the Fuente de los Chorros, which can be considered its birth, to Vado Carretas, the Guadalanimin is watched by a high wall, the Cabrilla saw, which rises almost 1000 meters above its waters, and is shown in a succession of poyos and cliffs. In this Sierra there are some of the highest peaks of the Natural Park, such as the Cerro de los Tornajos, the Pico las Covachas or the Empanadas, which exceed 2,000 m. This saw is also the limit with the province of Granada.

The river is surrounded by beautiful pastures, cortijos and fields of abandoned crops, and with them great nogueras and other fruit trees that show us life in other times. Some of these corijos are in places that are remnants of peace and invite us to make a stop and enjoy the landscape.

We suggest...

• Make the route from Fuente Steel to the Vado de las Carretas in order to admire these landscapes as a whole.

• Stop you in the forest of complaints you'll find on the way.

In Cazorla take the Sierra road (A-319) until the crossing known as the Empalme del Valle. Turn right on the JF-7092 road and after passing the bridge over the Guadalquivir River (4 km from the Empalme) follow the left track (JF-7091). Passing the Sail of San Pedro and the Strait of the Perals we find on the right the ruins of the forest house of Fuente Econo.

Since 2003, it has held a cattle fair in August, which had historically been one of the largest in the province of Jaén.
