Through forests, following the trail of a mysterious mining railway

An old mining railway, abandoned to its fate more than 70 years ago, climbs from the outskirts of Burgos to the Sierra de la Demanda mountains through beautiful, almost untouched countryside on the banks of the River Arlazón. Another of the great contributions of this small railway is that it brought to light the archaeological site of Artapuerca.
