The Colombus Zoo and Aquarium, Arguably the best zoo in America. Has over 7,000 animals, a water park attached, Discovery Reef, and a 100,000 gallon salt water aquarium. They offer many different shows and events and many places to stay near by. Plus affordable prices. I loveeee animals, so i must plan a trip around this zoo one day.
Phoenix Zoo - one of the younger zoos in the country. Not only it is a successful zoo, but it is a privately owned, nonprofit zoo. The Phoenix Zoo is open every single day of the year, including December 25th. Visit www.guestmob.com for quality hotels nearby.
