Marinho das Ilhas dos Currais

The islands serve as a vital sanctuary for numerous seabird species, including the Brown Booby, Kelp Gull, and Royal Tern. The surrounding waters teem with marine life, hosting over 60 fish species, sea turtles, and occasional visits from dolphins and whales. The area is particularly important for breeding seabirds, with thousands of pairs nesting on the islands annually.

While the rocky islands support limited terrestrial vegetation, they host various hardy coastal plants adapted to the maritime environment. The surrounding waters contain rich marine flora, including several species of algae and seagrass that provide crucial habitat for marine life. The underwater ecosystem features diverse coral formations and seaweed beds.

The archipelago consists of three small rocky islands of volcanic origin, formed during the Precambrian period. These granite and gneiss formations rise dramatically from the ocean floor, with the highest point reaching approximately 55 meters above sea level. The islands' rugged terrain and steep cliffs were shaped by millions of years of wave action and erosion.

The Currais Islands experience a subtropical climate typical of southern Brazil's coast. Average temperatures range from 18°C (64°F) in winter to 30°C (86°F) in summer, with high humidity year-round. The region receives significant rainfall, particularly from December to March. Sea conditions are generally calmest between November and March, making these months ideal for visiting the marine park.

The Currais Islands were historically used as a reference point for navigation by Portuguese sailors in the 16th century. The archipelago gained protected status in 2013 when it was designated as Brazil's first marine national park in the state of Paraná. The islands have long been recognized for their ecological importance, serving as crucial breeding grounds for seabirds and marine life.

The park's most distinctive features include its pristine waters, which offer excellent visibility for diving and snorkeling, and its dramatic rocky outcrops visible from Paraná's coast. The islands' isolation has helped preserve their ecological integrity, making them an important scientific research site and a premier destination for marine ecotourism. The surrounding waters are known for their rich biodiversity and well-preserved coral formations.
