Between Antequera and Estepa is this small protected lake and surrounding area. The reserve covers 168ha. A good time to visit is in winter, when there are many waterfowl.
Anyone interested in the Christian reconquest will be fascinated to know that it was here where Infante Don Fernando of Aragon knelt, kissed the sword of San Fernando and swore that he would not cease until he had retaken Antequera from the Moors (which he did, in 1410, after a five-month siege).
