There's a reverse zoo in Miami where the humans are caged and the monkeys run freeby Nathalie Basha

WATCH |  At Monkey Jungle in Miami, Florida, the tagline is "where humans are caged and monkeys run wild!"

Because Monkey Jungle originally started back in 1933 as a center to research primate ecology and behavior in a natural habitat, the park has recreated the natural habitats of several species over 33 acres of land. 

For the guests, that means walking into tunnel cages and observing the monkeys as they swing from the trees. It's the opposite experience from a standard exhibit, where the monkeys are confined and the people are not. 

There is, of course, a main perimeter fence that keeps the monkeys from escaping the park, but nothing restricts their movement inside the park. The cheeky macaques take full advantage of this (see that guy scaling the human tunnel?) 

Much of the park is covered by an impressive recreation of a subtropical forest, which is home to dozens of (ahhhdorable!) squirrel monkeys. Guests can interact with them by luring them down from the trees with nuts and seeds. 

Miami's year-round warm weather enables the monkeys to live outdoors, enclosure-free, 24/7. 

The park continues to do a lot of conservation work through The Dumond Conservancy, which works on primate education, ecology, and primate behavior in the wild. (And now let's all say 'awwww!')
