What Arab Emirs once called Wadi al Kabir, the Great River, is today known as the Guadalquivir. It flows for six hundred and fifty kilometers before arriving at its union with the Atlantic Ocean in the salt marshes of Doñana, the greatest European paradise of wildlife. We travel along the length of the Guadalquivir guided by a fox, meeting many other creatures and taking in the stunning scenery.
