El Fondo and the Salinas of Santa Pola as well as the surrounding area formed part of the Albufera of Elche known to the Romans as "Senus Illicitanus".

The natural park has a semi-arid Mediterranean climate due to its location in the south east of the Iberian Peninsula.

The peripheral pools, are more saline and contain better quality water than the reservoirs and various species typical of salt marsh are present, such as sea lavender, shrubby seablight and glasswort.

It is also possible to find other species such as the avocet, the black-winged stilt, the collared pratincole, the crested coot, the European penduline tit and the moustached warbler.

[4] The park is served by the Alicante-Murcia motorway, with an exit at the Crevillent Station leading to the village of San Felipe Neri.
