The zoo sits on 125 acres and houses over 2,000 animals of 240 species. Check out the National Amphibian Conservation Center, the Great Apes of Harambee, the Arctic Ring of Life and, of course, the penguins. Wheelchairs and electric conveyance vehicles (ECVs) are available to rent on a first-come, first-served basis. While Segways are prohibited in the Detroit Zoo, visitors who have a personal Segway and a physician’s note indicating it is a prescribed mobility device will be offered the use of an ECV or wheelchair free of charge. Assistive listening devices are available in the Ford Education Center Theater. Call 248-541-5717 x3750 to arrange an ASL, oral or cued speech interpreter at least two weeks in advance.
