Whether you love them or you hate them, zoos have been a family-friendly attraction in America for nearly 150 years. Today, there are well over 10,000 zoos worldwide and over 2,400 in the U.S. alone. But where are the largest zoos in America, based upon total acreage, number of animals and attendance? For a closer look, here is a profile of just five of the largest zoos in the country and, not surprisingly, among the best in the world.
Bronx Zoo
2300 Southern Blvd.
Bronx, NY  10460
(718) 367-1010

Originally known as the Bronx Zoological Park when it first opened in 1899, the Bronx Zoo is the largest urban zoo in the country. Residing upon 265 acres a few miles northeast of Yankee Stadium, the world-renowned zoo draws more than two million visitors annually and features 4,000 animals representing more than 650 species. You will be able to enjoy several free exhibits such as the African Plains, Himalayan Highlands and Tiger Mountain, along with the option to see paid exhibits and attractions which includes the Children's Zoo, Zoo Shuttle and the Wild Asia Monorail. Due to the size of the park, visitors may not be able to see everything in a single day without using either the Zoo Shuttle or Wild Asia Monorail. The Bronx Zoo also has several seasonal cafes and food stands on the property, as well as the Dancing Crane Cafe, which operates year-round.
