The Cincinnati Zoo and Botanical Garden has been welcoming visitors since 1875, making it the second oldest zoo in the US. Located on 75 acres in the Avondale neighborhood, it is home to almost 2000 animals of 500 different species. The zoo is known for its conservation efforts, education programs and for its rare animals, including the Sumatran Rhino, the most endangered large mammal on earth. In addition to the animal exhibits, be sure to check the program schedule. Put together your own itinerary to watch elephants get a bath, view animal feedings, chat about tigers, or watch the Cheetah Encounter show. While you're strolling around, admire the beautiful plants all around – there's a reason that Botanical Garden is part of the official name. View the butterfly gardens, pollinator garden, rain gardens and more. The zoo also offers train rides, a carousel and a 4-D Special F-X Theater.
