The 3,481 hectares (8,600 acres) Itaúnas State Park, created in 1991, is named after the Itaúnas River, which runs through the park for 34 kilometres (21 mi).[1] The river approaches the coast at the settlement of Itaúnas and then runs southwest, parallel to the coast behind a sand bar, before entering the Atlantic Ocean to the north of Conceição da Barra.[2]
