Laguna de Fuente de Piedra is the largest lake in Andalusia and offers a privileged enclave for the reproduction of the flamingos, winter season and the migratory passage of various birds. The lake is home to the largest colony of flamingos on the Iberian Peninsula and the second largest in Europe.
Due to the type of substrate, the evaporation of water causes the salt to crystallize on the surface. The exploitation of this resource, which was abandoned around the 1950s, dates back to Roman times. The old dykes, walls and channels used for this purpose turn out to be essential today for nesting flamingo and other species of waterfowl.
The landscape of this area, of very soft relief and covered with fields of olive trees and cereal, is dominated by the enormous lake, in which the ecological interest for the important colony of flamingos that it houses, is joined by the scenic beauty of its extensive sheet of water. Even in dry years, when the level of the lake decreases, the spectacular nature of the area disappears.
