While it's not quite at the level of, say, the Henry Dooley Zoo in Omaha, or the San Diego Zoo, this is a very competent zoo with plenty of large exhibits and a wide variety of animals. Has a good sized children's area, and provides nice views of the towers of the Texas Medical Center. Surrounded by the beautiful Hermann Park to fill the rest of your day.
