Flamingos, parrots, and macaws are some of the more colorful inhabitants of this privately run park. Right outside the Parque Nacional Foz do Iguaçu, it's an interesting complement to a visit to the falls. A winding path leads you through untouched tropical forest and walk-through aviaries containing hundreds of species of birds. One of the amazing experiences is the toucan enclosure, where they are so close you could touch them. Iguanas, alligators, and other nonfeathered friends have their own pens.
