Doñana National Park occupies marshland at the mouth of the Guadalquivir River, a fragile ecosystem and ideal refuge for migratory birds and the Iberian lynx. The park is interesting in terms of the beauty of its landscapes and the great variety of its natural environments: vast pine groves, areas covered in scrub, or cotos. The park can be explored by 4x4 from El Acebuche in the protected biological reserve and by foot in the nature park.
