Monkey Jungle is a 30-acre wildlife park established in 1933 for the exhibition and study of endangered monkeys in semi-natural habitats. Many projects have been conducted at the park, which is a tourist attraction in the Miami, FL area. 

The park has about 400 primates of 30 different species running loose. Guests walk through a series of tunnel cages. Its 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.^[1]
