The Vía Verde de la Sierra runs along the old Jerez-Almargen railway line. At present, 36.5 km are passable, distance and the first 8.5 km from Olvera to near the Navalagrulla station runs on asphalt and the following 27 km on gravel road, except for the last kilometer before reaching Puerto Serrano that is asphalt again.
La Via Verde de la Sierra unites the towns of Puerto Serrano and Olvera. Along this route you can enjoy a great variety of landscapes, observing the transition between an eminently agricultural landscape to another mountain, alternating with masses of Mediterranean forest (holm oaks, gall oaks, carob trees, mastic, olive trees, etc.).
In these landscapes, water is the common denominator, following the course of the Guadalete and Guadalporcún rivers, where we find a very diverse riparian vegetation (ash trees, black and white poplars, tamarisks, oleanders…).
It goes over 4 viaducts, goes through 30 tunnels and has 5 stations to rest during its journey. In the following map you can see the exact location of each infrastructure.
The 30 tunnels in order of passage from Puerto Serrano to Olvera are Indiano (455m), Reyerta (67m), Bastián (87m), Castellar (68m), Azares (35m), Esqueleto (500m), Galletón (250m ), Small plane (125m), Shaved (196m), Castillo (990m), Coripe (175m), Stubborn (120m), Atajo (169m), Zamarra (275m), Alberquilla (122m), Zaframagón (685m), del Navazo ( 105m), de la Francesa (115m), Faloir (345m), Navalagrulla (42m), Dehesa Nueva (165m), Chopera (250m), Descanso (285m), de la Higuerilla (275m), del Mushroom (60m), de La Colada (200m), Salado (160m), Yaja (70m), Mulo (60m) and Olvera (170m).
The route is very flat with slopes of 2-3% along the greenway, first you go down to Puerto Serrano and then return to Olvera passing through the town of Puerto Serrano and along the Sendero del Guadalete, we join the Greenway at the Junta de los Ríos. In this way we get to know the town of Puerto Serrano and a beautiful path along the river.
Passing Puerto Serrano there is a small climb with little difference in level (+100m approx) the rest is all flat. The route begins at the old Olvera Station, where the “Vía Verde de la Sierra” Interpretation Center is located.
The natural landscape that runs through the Vía Verde, between illuminated tunnels and viaducts that “hang” becoming surprising balconies, is mainly dominated by the influence of the rivers Guadalete, Gaudalporcún and, in the highest part, Gaudamanil. It passes through places as spectacular as the Peñón de Zaframagón, the largest vulture reserve in Andalusia and one of the most populated in Europe.
Subsequently, the Vía reaches another of the recommended accesses, the Coripe Station, to end at the Puerto Serrano Station, which rises above a cliff overlooking the Guadalete valley.
