This 36km, relatively flat route between Olvera and Puerto Serrano via Coripe is regularly labelled the finest of Spain’s vías verdes (greenways; railway lines transformed into traffic-free thoroughfares for bikers, hikers and horse riders). It's one of 23 such routes in Andalucía that together total 500km. Four spectacular viaducts, 30 tunnels and three stations turned hotel-restaurants await amid rugged mountain terrain.
Ironically, the train line that the greenway follows was never actually completed. Constructed in the 1920s as part of the abortive Jerez–Almargen railway, it was abandoned during the civil war. After languishing for decades, it was restored in the early 2000s.
