Vías Verdes (Green Paths) are disused railway lines; there’s more than 2000 klms in Spain, that have been restored for walkers and cyclists.
We walked the Via Verde de la Sierra, 36 klms from Puerto Serrano to Olvera across and through the mountain range of the Cádiz Provence. The rail line was conceived at the beginning of the 20th century but the Spanish Civil War brought work to a halt. All the 5 stations, 30 tunnels (one a kilometer long), and 4 viaducts were built; a huge engineering feat. But no tracks were laid and no trains ever ran!
Day 1 – Early bus from Sevilla to Puerto Serrano and 15 klms walking to the Coripe Station, now remade as a comfortable hotel bar restaurant.
Day 2 – To the end at Olvera Station, 21 klms. We had a good and enjoyable walk; cool weather, plenty of tunnels, rugged ridges, goat farms and olive trees, glimpses of the Castle at Olvera to encourage us on.
