Monkey Jungle is a renowned 30 acre wildlife park established in 1933 for the exhibition and study of endangered monkeys in semi-natural habitats. Many novel and innovative projects have been conducted at the park, which is also a popular tourist attraction in the Miami, Florida area. The park has about 400 primates of 30 different species running loose. Guests walk through a series of tunnel cages and the park's tagline is "Where the humans are caged and the monkeys run wild." It includes an Amazonian rainforest, the only semi-natural tropical rainforest found in North America.
