The Philadelphia Zoo was the first true zoo in the United States, and is still one of the premier zoos in the world. It is a wonderful experience for people of all ages to spend a day outdoors wandering along the variety of trails spread over 42 acres, and look at the wonderfully well maintained animals, many of which are endangered. Big Cat Crossing, which allow the animals to travel along suspended and ground-level mesh structures throughout parts of the zoo, and the outdoor aviary where guests may hand-feed exotic birds.
Very well maintained and large area. Debasree Sarkar, Trip Advisor
