Spread across 350 hectares (865 acres) of land, the park is a natural treasure of Buenos Aires. Forty years ago the plans were to build a sports complex and residential accommodation, but as time went by, the local fauna and flora reclaimed the land and it became a natural reserve by the river. It is divided into four zones, of which the most dominant are the woods, the lagoons, and marshlands, inhabited by ducks, storks and swans; and finally the River Plate banks. Offering vistas of the city's skyline, the park is reminiscent of the likes found in cities of San Francisco and New York. This park is an ecological microsystem where several species of animals and plants of the Litoral and the Argentinian plains (Pampas) can be found. There is also a flora and fauna interpretation center where curious souls can satiate their thirst for knowledge of the flora and fauna of the park. A haven for outdoor enthusiasts, the beauty of the park can be explored through various trails.
