Sierra de las Quijadas National Park, National park in San Luis Province, Argentina.
Sierra de las Quijadas National Park is a protected area in San Luis Province spanning more than 73,000 hectares, defined by red cliffs, natural terraces, and deep canyons. These formations developed over millions of years through geological processes that continuously reshaped the terrain.
The area was settled by the Huarpe people, who produced pottery and left behind archaeological remains including about twenty ceramic furnaces. These ancient production sites demonstrate a long history of human presence in the region.
The region was home for centuries to communities who hunted, gathered, and made pottery, leaving visible traces across the landscape. These deep connections to the land continue to shape how people today understand and value the place.
The park welcomes visitors and offers guided tours to explore the landscape, with administrative services available in San Luis city. Plan for sufficient time to explore the different areas, as the size of the site means multiple days may be needed for a thorough visit.
The area preserves fossils of two pterosaur species, including one with specialized teeth forming a basket-like structure for filtering microorganisms. These prehistoric discoveries show that flying reptiles once inhabited the region.
