The sequence of beaches heading south from Baía Formosa is as follows: Mirante, Cacimba, Pontal and, in the Sagi region, Sagi, Farol and Bacopari.
Sagi beach: This beach extends from the town of Sagi to the Guaju River at the state border. It is a long beach with a few small bays.
Bacopari beach: Extending from Baía Formosa to Rio Sagi, a small river just prior to the village of Sagi.
Bacopari lighthouse: The Bacopari lighthouse is situated on Bacopari Beach. From its height of 30 metres, one sees an impressive panoramic view of the coastline as far as the small fishing village of Sagi, located on the border of the state of Paraíba. On weekends and high seasons, local and visiting beachgoers concentrate in this region. Some of the better pousadas (inns) and some stunning views are found on the street leading to the beach.
Farol beach: Farol (lighthouse) beach is the name of the small strip of sand directly in front of the lighthouse.
Pontal, Cacimba and Mirante beaches: These beaches form part of the Baía Formosa region.
Also visit Cachoeira da Destilaria (distillery waterfall), where the waterfall forms a lovely natural pool, good for swimming.
Other beaches in the region go by local names such as Cotia, Barreirinha, Peroba, João dos Santos, do Amor and da Cacimbinha, where a pool of fresh water is found.
Natural Heritage Private Reserve of the Senador Antônio Farias 'Mata Estrela': Known as 'Mata Estrela' (Star Forest), this is an undeveloped stretch of forest of approximately 2,400 square hectares, preserved in 1990 by the state of Rio Grande do Norte for conservation purposes and for the study of its wonderful natural attributes, surrounded by forests, dunes, lakes, rivers and beautiful beaches. In addition, it is the habitat of numerous threatened plant and animal species. In the year 2000 it was declared a Natural Heritage Private Reserve, thus becoming one of the most important natural reserves in the country.
Of note regarding the region’s flora can be cited such trees as pau-brasil (Brazilwood), gameleira (Ficus), sucupira (Peonia), peroba (Desert Rose) and pau ferro (Ironwood) as well as palm trees, orchids, bromeliads and vines, among others.
Along with numerous samples of the native pau-brasil, the Mata Estrela is also home to the oldest tree in the Brazilian northeast, a millennial gameleira approximately 30m high whose canopy extends to a diameter the size of a sports gymnasium. A bend of the trunk allows passage right through the tree. To hug this tree, 15 people holding hands would be needed.
Fauna include the sagüi and guariba monkey species (the latter one threatened by extinction), a great diversity of birds, reptiles and snakes and a rich sample of insects.
Lagoa Araraquara - Coca-Cola Lake: Lake Araraquara, also known as Coca-Cola Lake, is remarkable for its dark waters containing medicinal properties. It is located in the interior of the Natural Heritage Private Reserve of Mata Estrela. Due to being the country’s largest stand of Atlantic Forest on dunes, the Mata Estrela Reserve contains a water spring. In all, 19 pluvial bodies of water are found within the forest stand.
Chief among them is Lagoa Araraquara, better known as Coca-Cola Lake, in virtue of the dark reddish color of its waters. With an area of 16.8 hectares, approx. one thousand visitors per month visit during the summer season. Coca-Cola Lake is believed to possess medicinal healing and rejuvenating properties, due to its thermal waters, rich in iron and iodide. The dark colour results from native Mata Estrela plant roots, which accumulate at the lake bottom.
Smaller lakes are also found, such as Junco, Cutia, Cavalos, Bumba and João Linho, which, in during times of high drought, diminish in size due to the lack of rainfall and evaporation.
Guaju River: The Guaju River empties into the ocean at Sagi Beach and divides the states of Rio Grande do Norte and Paraíba. The perfect sandboarding dune sits near the river. Vendors have established tents there where they sell drinks and it is possible to rent a board to ride down the dune. Boat excursions in jangadas (local artisanal sail fishing rafts) leave from here headed upriver toward the manguezal (mangrove forest) and for the famous mudbaths. Mud drawn from the marsh and spread over the whole body is said to have aesthetic properties.
