Laguna de Medina Natural Park
This is the most important reserve of the lagunas (lagoons) close to the Bahía de Cádiz. Like the other lakes in the area (the Complejo Endorreico de Chiclana, Complejo Endorreico de Espera, Complejo Endorreico de Puerto Real, Complejo Endorreico de El Puerto de Santa María and Las Lagunas de Las Canteras y El Tejón), the freshwater Laguna de Medina is an important site for overwintering waterfowl and as a breeding ground for birds such as the white-headed duck and purple gallinule.
