NAUTILUS MERGULHO

Arraial do Cabo, Brazil

Nautilus Mergulho operates from Arraial do Cabo, a town we know well for its colder, nutrient-rich currents that draw in larger pelagics. They’re a solid pick for divers looking to explore the area’s signature sites, like the Grotta Azul or Ilha dos Franceses. Expect an emphasis on boat diving to access these deeper, more exposed reefs, often with some current. It’s a good choice for divers comfortable with those conditions and keen to see turtles, stingrays, and occasionally some small sharks.
