Dois Irmãos State Park, State park in Recife, Brazil

Dois Irmãos State Park is a large protected area featuring tropical forest and an integrated zoological garden on its grounds. The zoo occupies a small portion of the overall park land and displays native and non-native animal species within a forested setting.

The park began in 1916 as the Horto Florestal de Dois Irmãos on land of the Engenho Dois Irmãos, owned by Antônio and Tomás Lins Caldas. In 1939 the Jardim Zoobotânico de Dois Irmãos was created, with Vasconcelos Sobrinho as its first director. Law 9.989 of 13 January 1989 turned it into an ecological reserve, and in 1997 it took the name Parque Dois Irmãos.

The name Dois Irmãos (Two Brothers) comes from the engenho owned by Antônio and Tomás Lins Caldas. The park hosts pioneering environmental education and captive breeding programs, and its zoo represents the North and Northeast regions of Brazil. Near the end of the zoo, a children's playground recreates a small village.

The park is most easily visited during daytime hours and has pathways throughout for exploration at various levels of difficulty. Educational centers within the grounds provide information about the different habitats and species you will encounter.

The reserve takes its name from the engenho Dois Irmãos, the sugar estate of Antônio and Tomás Lins Caldas on whose land the forest nursery was founded in 1916. The zoo section covers 14 hectares, while the Atlantic Forest reserve covers roughly 373 hectares, and the park keeps about 650 animals of more than 120 species, over 50 of them on threatened-species lists.
