Parc marin interjuridictionnel Isla Pingüino, Marine protected area in Santa Cruz, Argentina.

Parque interjurisdiccional marino Isla Pingüino is a marine protected area extending along the Argentine Sea, encompassing numerous islands and islets with varied marine ecosystems. The park covers approximately 159,526 hectares (394,000 acres) and features diverse coastal formations and rich ocean habitats.

The protected area was established in 2012 through a collaborative effort between national and provincial authorities. This partnership aimed to preserve the unique marine environments found along this stretch of the Argentine coast.

The park's name comes from Isla Pingüino, the largest of its coastal islands, where Magellanic penguins nest in the greatest numbers. The same island holds the only breeding colony of southern rockhopper penguins on the Patagonian coast, a fact that draws researchers and wildlife visitors to the reserve.

To visit the protected area, arrange access through the management office in Puerto Deseado, which operates during weekdays. It is wise to contact them in advance to confirm conditions and plan your visit properly.

Isla Pingüino holds the only breeding colony of southern rockhopper penguins on the Patagonian coast, according to the park's sources. The much larger Magellanic penguin population outnumbers them, so visitors scanning the cliffs should look for the rockhoppers' yellow crests among the far more numerous Magellanic birds.
