The Park

It was declared a Protected Area by the Government of the Province of San Juan on November 3, 1971, mainly for its paleontological value, which was subsequently confirmed with the Declaration of World Heritage by UNESCO on November 30, 2000.

WILLIAM SILL, who was a leading paleontologist and researcher, was the author through his scientific publications that Ischigualasto is recognized worldwide and responsible for exposing to international organizations the geological and paleontological importance of the place obtaining the highest recognition to a protected area. That is why the Interpretation Center that is in the tourist circuit, deservedly bears his name and inside it the visitor can know fossils that will allow you to better understand the evolution of that species that interests both young and old, as well as They are the dinosaurs.

The Park has a “Management Plan”, where its fundamental pillars are the care of the anthropological heritage, the development of the host communities as well as the tourist activity.
