This part of the Doñana Natural Park, in the province of Cadiz, is located next to the mouth of the River Guadalquivir. Although it was heavily transformed in the past, it is still one of the most interesting areas for birdwatching in Doñana.
This area is the best in Doñana to observe two of the most threatened species: Marbled Duck and White-headed Duck. It is also an excellent place to watch waders and sea birds, among them Balearic Shearwater. One outstanding sight is the presence of one of the rare European colonies of Little Swift and some pairs of Rufous-tailed Scrub Robin.
We will visit the East bank which consists of large areas of marsh, some parts of which have been drained for agriculture. Towards the Estuary, there are salt pans which attract a large number of waders and waterfowl. Here we will see where the river meets the sea and travel along the coast between Sanlúcar de Barrameda and Chipiona.
Some of the hotspots to visit are the marshes in Trebujena, the Umbrella Pine forest in La Algaida, Bonanza salt pans, Montijo´s beach and Chipiona.
