With an immense coastline, thousands of islands and a wealth of biodiversity, Brazil is an excellent destination for freediving (done on the surface, with snorkel) and scuba diving (with 227 compressed air cylinder in order to reach the depths). For snorkelers, the natural pools formed by reefs in Porto de Galinhas, Maracajaú, Taipus de Fora and along the Coral Coast, on the shore of Alagoas, are perfect for observing marine fauna. And there is no shortage of places with good visibility for a veritable baptism. Starting with the ecological sanctuaries of Fernando de Noronha, Abrolhos and Bombinhas, where nature reigns supreme. For lovers of pirate stories and lost treasures, the north coast of São Paulo and the south coast of Rio de Janeiro are lled with shipwrecks that remain largely unexplored. Even the heart of Brazil has its surprises. In destinations such as Jalapão, Bonito and Chapada Diamantina, rivers and lakes will give you the feeling of being inside a large natural aquarium, inviting visitors to the pleasurable pasttime of oating. For a picturesque experience, cave-diving provides the thrill of immersing oneself surrounded by speleothems and rare sh species adapted to darkness. A route for adventurers in search of the mysteries and treasures of our submerged nature.
