Considered by many to be the gold standard of zoos, the San Diego Zoo pioneered the concept of open-air, cageless exhibits that re-create natural animal habitats, with different species living side by side with native vegetation. The San Diego Zoo also operates the San Diego Zoo Safari Park.

What began as a single exhibition during the 1904 World's Fair has grown to be the St. Louis Zoo with over 700 different animal species. If you've got little ones, don't miss the children's zoo and its see-through slide through the otter pool and up-close animal encounters.

This private petting zoo outside of Miami is home to many exotic animals. The Zoological Wildlife Foundation is particularly known for its one-on-one encounter experiences with animals such as baby tigers, lemurs, and monkeys.

Open since 1965, the 40-acre Fort Wayne Children's Zoo is home to more than one thousand animals in Franke Park. You'll find animals from different parts of the world, such as Africa, Australia, and Indonesia. Don't miss the ever-popular penguins and otters, and be sure to feed the giraffes. 

For more than a century, the 76-acre Memphis Zoo has graced Overland Park in downtown Memphis. The zoo is home to more than 3,500 animals representing over 500 different species, including the Giant Panda. In 2008, Memphis Zoo was voted the no. 1 zoo in the US on TripAdvisor.

The largest and oldest zoo in Florida, Zoo Miami is also the only tropical zoo in the United States. There are four main exhibit sections in the zoo -- Asia, Africa, Amazon and Beyond, and Australia. Don't miss a ride on the air-conditioned monorail, which provides an aerial view of the zoo and a convenient, comfortable way to move between sections.
