In the fountain we can see the catacamosque (Pinguicola vallisneriifolia), small carnivora plant endemic to the Park, which feeds on insects. In this place a signposted path of 1 '5 km is started, which ascends on a hillside from which you can see very good panorama of the Bucentaina and the Stone of the Hole.

SITUATION

In the km 2.2 of the Siles to Las Azeas road (JF-7012), it starts a forest track that leads to the Area after 1.5 km.

The Tiscar Falla is a sinistra tear fracture that borders the Quesada saw by the E, running always close to the Quesada- well Alcón road. The fracture plane is almost vertical. The failure has cut the southern end of the Sierra de Cazorla, moving the southern fragment to the NW about 8 km.

At the proposed point the failure plane can be observed, with associated failure rocks, as well as some horizontal strands that show the movement of this fracture.

There are two places to enjoy the Strait of Perals:

• Undoubtedly a good place to observe the beauty of this Strait is the lookout that appears on the left side of the Navas road. It's not signposted, so you have to pay attention, though it has no loss.

• In the valley of Valdetrillos in the ascending direction there is a track that can be seen from the lookout. To get to it you have to turn back on the runway of the Navas and take the road cut by a chain that goes to the right. We have to cross the bridge over the Rambla stream. After a period of half an hour walking we view the basin of the Valdetrillos stream from where the Strait of the Perals and the lookout that has been referred to above are observed.

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). Between the km 27 and 28 of the road signs is the lookout with views of the Strait of the Perales.

• Your access is made on foot field through.
• The person who best knows and has studied the centenary olive trees in Martos is Mr. Ciriaco Castro Toro, retired technician of the City Council.

Inside there is a figure of a Crucified Christ as well as a Cross Way that was donated by the marriage Mr José Martínez García and Mr María Velasco Czech in 1989. It was rebuilt in 1984.

Behind the Palace is a house that was once a hermitage of St. John the Baptist: it retains the structure of the 17th's conventual gates, a small swordsman and, of course, remarkable paving as the tradition of Jabalfifth commands.

They are found on the stony and slope slopes, forming clear forests in which they coexist with some pine of several species (Pinus nigra salzmannii, Pinus pinaster and Pinus halepensis), according to the altitude and orientation of the slope, as well as cornicabra (Pistacia terebinthus), ruscos (Ruscus aculeatus) and a herbaceous entourage such as charts, rompesacos and cerveres (Poa bulbosa, Cynosurus echinatus, Aegilops, and the acrachacellus (Arrachacus), and the acellus (Arrachatus), and the other (Arrachus).

From the Recreative Area of Linarejos, we walk along the track that goes up the hill. We will go through a quarry and a barrier, these are two indicators that confirm that we are on the right track. At 3 km from the Recreative Area we will see a detour to our left, a track that enters us into a rock maze. It is a torque, in which this formation of oaks and juniper is extended. Two leads are coming out to our left, one after the other, and they both get us into this torcal. If we do not want to go too far, because it is a difficult ground to go through, from the main track we see this plant formation in the same way.

Our goal is to see one of the most spectacular oak trees in the Park, where we will see large, very large oak trees and a forest of tale. Give the place where we left the car, we continue on foot on the track about 6 km. The rise is easy and uncomplicated.

We'll get to a crossroads, we'll follow right. A little higher, a source is intuited under an oak. For that place, to the right of the track and above the source we will find large copies of oak, although in reality we have been walking through a magnificent oak for a long time. The crossing of the track is where the old forest house of the Fountain del Roble was. This is where the burning reaches all its magnificence.

In this forest dominated by the oak we find some other complaint (Quercus faginea), serbals (Sorbus domestica), pespejones (Sorbus torinlis), majuelos (Crataegus monogina), skirmishes (Rosa spp.), laureolas (Daphne laureola), thorns (Berberis vulgaris australis), torvizcos (Daphne gidium), peonies or mountain roses (Paeonia broteroi), orchids (Orchis, the dominant, Chiphiphipis, and the contiguera (Ophanacteria), and the domineas.

In our saws we can see many oak forests. For example, on the rise to Santiago de la Sword from Tobos, on the Esperilla, before Fuente Steel, or on the access track to the Pegueras. The name of engraving has meant Mediterranean forest, but the matter is not so simple.

Rather, we should say that burning is a phase of the Mediterranean forest. The lauroid forest, which we discussed elsewhere, is also Mediterranean forest. In any case, the engraving does exist as such, in addition to the fact that its main component, the encin (Quercus ilex ballota), is in almost all the plant formations of the Park, with the exception of the summits and the cold deciduous forests, of the high mountain.

LOCATION

From Coto Ríos we take the road A-319 towards the Tranco and less than a kilometer away to the right towards the campsite of the Llanos de Arance. We overcome it and follow it (the road becomes a forest track), until it reaches the control of Aguamula. As we pass it we follow the track to the left, discarding another one to the right, from here we will travel the right margin of the Tranco reservoir. We take the first detour to be presented to our right at 2.1 km from the above control. It is a great crossing where the track is widened and where we must turn to our right making a closed curve that places us almost 180º to the sense of our march. This is the track that goes up to Majalalto, passing through the Fountain del Roble. In that place we left the vehicle, as the track is closed to traffic with a chain.

We can deduce that this was the dominant landscape a few centuries ago, when after the Reconquista arrived in this village the first inhabitants attracted by the wealth of this dehesa and the possibilities it offered, not only for its cattle, but also to make it "land of bread."

Until the 19th century there were still many oak feet, but it was during this and especially during the first years of the last 20th century that they were significantly reduced, in some cases to devote the land to cereal, vineyard or olive trees and in others to obtaining charcoal. However we can still see some spots of indigenous vegetation in the vicinity of Cabeza Montosa and the hill of the Peones.

This fierce struggle of man against the dehesa has allowed some of the oak to be kept so that its shadow would cover the reapers and the flocks that took advantage of the rashes, or to collect the stones that were taken from the fallow. The fact is that in cases like this, in the face of lack of competition, it is possible that the few specimens of oak have grown more vigorously.

Its trunk has a considerable bearing for an oak and its cup is the widest in the entire province with about 30 meters in diameter and 300 meters in perimeter. This oak is part of the catalogue of unique trees in Spain and is waiting to be declared as Good of Natural Interest, not in vain is of the few millennia trees left on the peninsula.

It is located very close to the railway station of Cabra del Santo Cristo, next to the cortijo of "La Viña." We can access up to the millennial oak through an asphalt road, in good condition, that leaves from the passage to the level that is in the Station. We just have to follow the direction of the signage and within 2 km we will have no doubt when we see it to the left of the road, while to the right the above-mentioned cortijo of the Viña will serve as a reference.

From Cabra we can also walk along the lane that runs through the Fifth, Alamedilla and Gamelloncillo, for which we will walk through space of about 6 km (only one way). It is advisable to finish our route at the station of Cabra and stay in your canteen to take a refreshment with good viandas to recover from the effort, or, if we want to continue to know this ancient dehesa, continue track and return to Hidalgo and the Mill Barranco, but then we will extend our route to about 18 km and have walked by asphalt for a considerable part of the road.
