So it's totally impossible to get through with mountain bikes. After miles through brambles, thistles, holes, pits, stopped by an impassable pond so U-turn for miles

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.

Railway tunnel no. 23 of the Sierra Greenway Nature Trail. Located 923 meters from the previous tunnel, it is 125 meters long and has no artificial lighting, so a flashlight is recommended. This tunnel is excavated into the side of a clay hill.
