I love the zoo. I really like the Philadelphia Zoo too. It's the oldest in the country, and while most of it has been redone several times, you can tell that it's not a new zoo because some of the habitats are much smaller that what you would find at the San Diego zoo or another huge zoo. The animals seem well cared for and that's what's important. Parking is expensive and often a good hike away. You can get there by public transit, but I wouldn't recommend it if you're not familiar with the different routes. And, if you have some extra cash, definitely go up in the Zoo Balloon, It's a blast and offers great views of the city.
