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.

Mediterranean mountain area, also called Sierra de Alta Coloma, with high-value geological and vegetable formations such as oaks, complaints, junips and savannas. The following enclaves are highlighted: the Monastery ravine, the Quebrajano reservoir, the Valdecarazos river, the Palo Stone, the Netherlands Prados cortijo or the Alberquilla lookout.

Location: Sector west of the municipal term.

Distance: 3-7 km.

Medium: by all-terrain vehicle, by bike and on foot.

Access route: By the JV-2.228, which leaves directly from the urban centre, and through agricultural and forestry roads.
