The road goes parallel to the river and, on its sides, there are impressive calares with magnificent views of the saw. As you pass the village of La Toba, the river remains in the charming reservoir of Las Anchuricas, one of the most beautiful of the Sierras de Cazorla Natural Park, Segura and Las Villas, The valley offers pleasant visits around you that will allow us to know more about the Sierra de Segura, such as the village of La Toba, a place where water is the great protagonist, or the nearby populations of La Fuente del Esparto, La Peguera del Madroño or Las Gorgollitas.

On the JF-7038 road, from The Utrera Strike to Miller's Boards.

Traditional constructions have only been modified, although the most rewarding is the view that you can enjoy from the village that really constitutes a natural balcony open to an overwhelming landscape in which stands out on the whole Calar del Cobo with the Puntal of the Mass.

If you like them, you can't stop visiting the Umbria, as it's a very good area for the collection of these mushrooms. In addition, a delicious unmarked road leads to the nearby village of Cabeza Gorda, located on the opposite side of a mountain, which is naturally called Morro de Cabeza Gorda.

The upper part of the Borosa River, has a scalated profile for the development of pozas and waterfalls in which travertine terraces are formed with spectacular botroidal calcite morphologies that were precipitated during the most humid and warm periods of the Quaternary.

Although travertine appear throughout the river, the highest concentration is located in the sector between the organ jump and the electric power plant. Its formation is due to the precipitation of calcite caused by the tear-up of the river waters produced by the turbulent regime of the water leaps in the areas with the greatest slope. This precipitation occurs in areas of dense vegetation receding elements of plants and producing subvertical sheets known as cascade facies.

It is a travertine of hectometric dimensions, located on the southern side of the valley of the Segura River, in a sector very close between the Puntal of the Vultures (1680 m) and the Calar del Pino (1567 m). The travertine, attached to the steep carbonate side of the Cretaceous, has a higher flat morphology, on which the picturesque village of La Toba is located.

In the vertical walls of the travertine there are several karmic resurrections with spectacular water jumps and great beauty carbonate morphologies. Stratigraphically, the uprisings are at the base of the upper Cretaceous dolomies, which constitute the aquifer, on the waterproof levels that belong to the lower Cretaceous.

Location: To the south of the town, in the natural park of Cazorla, Segura and Las Villas.

Distance: 42 km

Medium: By vehicle, by bike and on foot.

Access route:: On the road A-319 towards La Iruela; at this point, after going 13 km, we will take the Chorro road, then turn away by the horseshoe road leading to Puerto Llano.

The hill of the Poyos de la Mesa is an inverted relief in which the dolomies of the Upper Cretaceous and the limestones of the discordant Miocene on them are affected by a sincerity perfectly visible from the north.

The fold is more tight in the older materials (Cretaceous dolomies), and is more open in the discordants (myocene limestones). Both litological sets flare at the top, very steep, of the relief. Between them there is a well-developed canchal, which marks approximately the axial plane of the fold.

The total power of the section is over 150 m. On a few sucrose dolomies attributed to the lower and medium Jurassic we find materials from the upper Kimmeridgian; they are limeals with large gastropods and corals that end up on an erosive surface with a crusts of iron oxides.

The following are limestones, locally sandy and margas, with various levels of interspersed calcrets; these materials are being decrified and dolomitised, giving way to stoned dolomies with abundant carbonous remains; this whole set of materials is of the age Hauteriviense- Barremiense. The lower Aptiense is characterized by the presence of sands, calcareous sandstone and sandy limestone with laminations and cross stratifications as well as orbitolins at various levels. The materials of the upper Aptiense have abundant rudists and orbitolins. The Albibe is represented by dolomies with black songs and ghosts of rudists.

This saw welcomes the typical Mediterranean forest, with the rich and typical varied flora and fauna. Areas of pedestal steep, others with typical river vegetation, and the serrana area characteristic of Sierra Morena. As for its fauna, typical of Sierra Morena, we find many species of cynegetic species such as deer, boar, muflon, go, foxes, rabbits, perdices, hares, doves, etc. Its flora is made up of low mountain and native Mediterranean forest of oak, juniper, madroño, acebuchs, alcornoques, torviscos, complaints, rosemary, thyme, pellet, lentils, cornicabra, zarzas; large and large areas of jars, shrubs, some coniferous areas, reduced presence of areas of dehesa, fruit such as pomegranate, fig tree, membranel, typical talleds, chopos, juncos, canyizales and other river vegetation.
