Ilha Grande
Brazil · South America
Ilha Grande lies off the Rio de Janeiro coastline inside a state park and APA marine reserve, keeping its Atlantic reef largely pristine. Green and hawksbill turtles are resident, endemic Brazilian reef fish such as the Brazilian grunt and rock beauty are abundant, and the wreck of the Iate Clube freighter adds a wreck-diving dimension within recreational limits.
