Forty kilometres northeast of Ciudad Real, this small wetland national park is great for birdwatching. From the visitor centre, which has an exhibition on the fragile local ecosystem, three trails lead out along the lake shore and over boardwalks. From these, and the various observation hides – bring binoculars – you can see an astonishing variety of wildlife, including ducks, geese, kingfishers, flamingos, herons and other waders, tortoises and otters. Early morning and late afternoon are the best times to visit.
