A 135-meter-long viaduct, built using rectangular truncated pyramidal pilasters with mortared ashlars, is formed by the repetition of seven identical arches. It was built to span the Guadalporcún River crossing before it meets the Guadamanil River. The latter originates in the Sierra de la Lebrona mountain range in the municipality of Pruna (Seville) and flows into the Guadalporcún River just a few meters from the viaduct. The confluence of the rivers has created a wide floodplain. From this railway infrastructure, there is a privileged view of the Estrechón Canyon, a natural passage carved by the Guadalporcún River to traverse the foothills of the Zaframagón Rock. Just below, on the left bank of the Guadalporcún, we find the ruined building of what was once the Zaframagón mill. A little further west, other ruins can be seen. It is a small town built for workers on the railway line construction site.

Built to save the bed of the Azar stream. Less than 100 meters away there is a small rest area from where you have a good view of the Guadalete river at the exit of the Villalón meander, at the foot of the Cerro del Castellar.

The terminus of the Vía Verde de la Sierra between Olvera (Cádiz) and Puerto Serrano, built on the old railway infrastructure between Jerez de la Frontera and Almargen, built at the beginning of the twentieth century but never used due to a collective suicide of more than 20 inhabitants, which was created by a Masonic sect. The station is currently dedicated to rural tourism.
