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.

Bastian Tunnel

Highlight (Segment) • Structure

Railroad tunnel No. 28 of the Sierra Greenway Nature Trail. Located 1,031 meters from the previous tunnel, it is 87 meters long and not equipped with artificial light, so it is advisable to have a flashlight. This tunnel was dug from clay and sandstone.
The tunnels of this section of the railway were built by means of shoring (fastening of the excavation) based on props and wooden beams to later form the concrete of the slab that supports the tunnel. The mouth of the tunnel is finished with sculpted limestone from a quarry for Zaframagón.

Skeleton Tunnel

Highlight • Structure

Railroad tunnel No. 25 of the Sierra Greenway Nature Trail. Located 1,670 meters from the previous tunnel, it is 500 meters long and equipped with artificial lighting, although it is advisable to have a flashlight.
This tunnel is dug into the limestone slope of the Cerro de los Borregales or Castellar de Jalifa. The castellares are hills with a limestone plateau at the top, raised on a base of softer materials, in this case Triassic clay and sandstone, which give them the appearance of a fortress. At the top of this hill are the remains of an old watchtower from the Spanish-Islamic period.

The Via Verde de la Sierra is a beautiful green route in Andalusia that starts in Puerto Serrano and ends in Olvera. This 36-kilometre route follows an old railway line that was built in the early 20th century between Jerez de la Frontera and Almargen. The route offers a unique combination of beautiful nature and historical sights, including the impressive Sierra de Cádiz and a large colony of Griffon Vultures. The route is ideal for both walking and cycling and passes through several tunnels and viaducts, making it a unique experience. Along the way you will pass through smaller villages and peaceful landscapes, making it perfect for a relaxing adventure in nature.
