Diving in Brazil
Including Abrolhos Archipelago Marine Park, Arraial do Cabo, and Arvoredo Marine Reserve (Florianópolis). On the map.
The vibe
Diving here is defined by the sheer diversity of the Atlantic, ranging from historic shipwrecks to rocky volcanic formations that teem with pelagic life. The experience feels professional and well-supported by local operators who prioritize safety in currents that can be deceptively strong. Aim for the warmer months to maximize comfort, as the water temperature can drop significantly during the winter season.

Known as the 'Diving Capital of Brazil,' Arraial do Cabo benefits from a natural phenomenon called upwelling, which brings nutrient-rich, crystal-clear water and abundant marine life to its rocky reefs, arches, and passages. Divers frequently encounter groupers, moray eels, rays, and schools of pelagics.
Access. Located about 2.5 hours from Rio de Janeiro, with numerous dive centers operating daily boat trips directly from the local marina.
Notes. Water temperatures can be brisk due to upwelling, but visibility is often exceptional (up to 20-30 meters). Depths range from 6 to 35 meters.
