Now the highlight is right 👍; Picnic spot with beautiful panoramas.

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.

Just a few meters from the birdwatching observatory are the Visitor Reception Center and the Zaframagón Cantina, an ideal place to familiarize yourself with the Vía Verde's surroundings and a convenient spot to take a break and recharge. Managed by the Sierra Greenway Astronomical Association, the Vía Verde de la Sierra offers tours for astronomical observation and photography, as well as hiking, cycling, and birdwatching. Enjoy the opportunity to have a snack and rest.

One of the most beautiful cycle paths in Europe!

Railway tunnel no. 20 of the Sierra Greenway Nature Trail. Located 310 meters from the previous tunnel, it is 175 meters long and provided with artificial lighting; however, a flashlight is recommended. This tunnel is excavated in black limestone. The tunnels in this railway section were constructed using shoring (supporting the excavation) with wooden beams and props, followed by formwork for the concrete slab that supports the tunnel. The tunnel entrance is finished with hewn limestone from a quarry located opposite Zaframagón.

Viaduct of 237 meters long, built by means of truncated pyramidal pilasters with a rectangular plan with mortared bluestones. It consists of 9 openings, eight of which are the same, and the fourth (counting from the station) with a larger arch. It is the longest viaduct of the nature trail, built to cross the junction with the Guadalporcún River.

Viaduct of 83 meters long, built by means of truncated pyramidal pilasters with a rectangular plan with mortared bluestones. Formed by the repetition of 5 equal openings. It was designed and built to save a deep ravine dug by a tributary of the Guadalporcún River.
