Bike tour - a journey through time 🤣🚴

Amazing views over the valley of Algodonales

Railway tunnel no. 14 of the Sierra Greenway Nature Trail. Located 920 meters from the previous tunnel, it is 105 meters long and has no artificial lighting, so a flashlight is recommended. This tunnel is excavated in clay and sandstone.

After cycling for about twenty kilometres, you will arrive at the Peñon de Zaframagón mountain point. The mountain is inhabited by the griffon vulture. You can recognise the bird – if you see it up close – by its ‘fur collar’ around its otherwise bare neck. Entire families live on this 600-metre-high mountain. Dozens of birds soar high through the air in search of prey. They have chosen the location cleverly, because the mountain is situated on a gorge with a river. Sometimes a huge shadow of a bird falls over you when it is hovering just above you. That gives a strange feeling that makes you quickly look up. A little further on is a small nature museum that is particularly proud of its special camera with which you can spy on the birds. You can zoom in, which allows you to count almost every feather.

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.
