The Philadelphia Zoo is located in Fairmount Park, the largest urban park in the United States, and is one of the oldest zoos in the country. It was established in 1859 and covers 42 acres. The zoo is home to over 1,300 animals, including rare and endangered species such as the Amur leopard, the Chinese alligator, and the African wild dog.

One of the unique features of the Philadelphia Zoo is its Zoo360 animal exploration trail system, which allows animals to move freely above and around visitors. This allows visitors to see the animals in a more natural setting and provides a more enriching experience for both the animals and the visitors.

The zoo also has a number of popular exhibits, including Big Cat Falls, which features rare big cats such as Amur tigers, African lions, and snow leopards. Other popular exhibits include the McNeil Avian Center, which houses over 100 bird species, and the KidZooU, an interactive exhibit designed specifically for children.

In addition to its animal exhibits, the Philadelphia Zoo offers a range of activities and educational programs for visitors of all ages, including animal encounters, behind-the-scenes tours, and summer camps. There are also several dining options available at the zoo, including a café and a food court.

The Philadelphia Zoo is open year-round, but hours and admission prices vary depending on the season. Visitors can purchase tickets online or at the gate. The zoo is easily accessible by car, public transportation, or bike, and there is ample parking available on-site.
