Ilhas dos Currais Marine National Park, Marine reserve in Paraná, Brazil.

Ilhas dos Currais Marine National Park protects the Grapirá, Três Picos and Filhote islands, rocky headlands rising from the Atlantic with no beaches, plus surrounding reefs across 1,359.70 hectares. The archipelago lies 6.2 miles (10 km) off Praia de Leste, Pontal do Paraná, between Guaratuba Bay and Paranaguá Bay.

The Brazilian government established this marine reserve in 2013 through federal legislation, making it the third marine protected area in the country. The creation reflected growing efforts to safeguard coastal ecosystems from fishing pressure and development.

The archipelago is one of the main fishing grounds on the Paraná coast, used by small-scale fishermen from the state's shoreline. The park was created partly so that conserving fish stocks around the islands would benefit these artisanal fishermen working in the vicinity.

A national conservation authority manages the park and enforces rules against illegal fishing and construction to protect the marine ecosystem. Visitors are best served by joining authorized boat tours or guided trips to experience the reserve properly.

The three islands serve as nesting and breeding grounds for thousands of seabirds including brown boobies and frigatebirds that reproduce regularly there. These bird colonies are so numerous that visitors can observe them clearly from boats during tours.
