Via Verde Huéznar River
In the Sierra Norte Natural Park is this 18km-long vía verde (greenway) that follows the Huéznar river and the course of an old mining railway. The trains carried iron (hierro) from the mine at Cerro del Hierro to the station of Cazalla-Constantina, located 6km from Cazalla and 8km from Constantina, which was on the mainline.
