Dive sites in Brazil

Caieiras sits on the Mar de Fora coast near Fernando de Noronha's northeastern tip, featuring shallow reef terrain of basaltic boulders and scattered coral heads. Direct exposure to the open Atlantic brings surge and lower visibility during the trade wind season. In the shallow channels, juvenile lemon sharks patrol over southern stingrays and hawksbill turtles resting on the sand.

On the exposed Mar de Fora side of Fernando de Noronha, Trinta Réis features volcanic rock formations and large underwater boulders in clear Atlantic water. Submerged channels and crevices shelter resting nurse sharks and sand-buried southern stingrays. Ocean swells and tidal currents sweep across the site, requiring drift diving techniques.
