The Jardim Zoológico is Brazil’s largest zoo. It’s home to some 3000 animal species and is spread out over some 900 hectares, much of which is old-growth Mata Atlântica (Atlantic rain forest). As well as exhibiting caged animals, the zoo offers the Zoo Safari for an additional R$13; this is a 45-minute ride through large, fenced areas where animals are allowed to roam with relative freedom. Note that the zoo does not accept credit cards.
