Some 120km of disused railway, including three tunnels, 13 viaducts and 12 old stations, running across the olive-strewn countryside of southern Jaén and Córdoba provinces (and close to Córdoba's Sierras Subbéticas mountains), have been converted to a well-surfaced cycling and walking track, with gentle gradients and refreshment stops en route making for an enjoyable extended ride.

The track starts at the Polideportivo Las Fuentezuelas sports centre on the northwest edge of Jaén city. This is one of over 120 such vías verdes (greenways) around Spain, and the website has maps and plentiful information. Sport Bike, near Jaén train station, rents 24-speed mountain bikes.
