Campos del Tuyú National Park, National park in General Lavalle Partido, Buenos Aires Province, Argentina

Campos del Tuyú National Park covers 3,040 hectares in General Lavalle Partido, bounded by the Río de la Plata to the north, the Ría de Ajó to the west and the Arroyo las Tijeras to the east. Its flat coastal plain holds halophytic steppe, Spartina espartillares covering almost half the area, and small talar woods of tala and coronillo on higher ground.

The land was a private reserve run by Fundación Vida Silvestre Argentina, the local WWF branch, before it became a national park on May 13, 2009. It was the first national park created to protect the Pampean grassland ecosystem, and its main mission is safeguarding one of Argentina's last pampas deer populations.

The region preserves traditional gaucho cattle ranching practices that shaped the grasslands over many generations. You can see this heritage reflected in how the land is managed and used today.

The park lies several hours from Buenos Aires and is best reached by car. Check local access conditions before visiting, as some areas may have seasonal limitations.

The park is home to one of the last pampas deer populations left in Argentina. Visitors might also spot Geoffroy's cats and many bird species that are hard to find elsewhere.
