In 2026, general admission to the Oklahoma City Zoo and Botanical Garden typically costs around $16.00 to $20.00 for adults (ages 12-64) and roughly $13.00 to $16.00 for children (ages 3-11) and seniors (ages 65+). Children under the age of 3 are usually admitted for free. It is important to note that these prices can vary slightly depending on whether you purchase tickets online in advance (which usually saves a few dollars) or at the gate. The zoo also offers a "Zoo It All" pass, which often costs between $35.00 and $45.00 per person; this bundled ticket includes admission plus unlimited access to attractions like the Elephant Express tram, the Endangered Species Carousel, and the sea lion presentation. Parking at the OKC Zoo remains free for all guests. If you are a resident of Oklahoma City, be on the lookout for "appreciation days" or discounted tickets offered through local library programs. The zoo is a "Blue Star Museum," meaning active-duty military and their families often receive free admission between Armed Forces Day and Labor Day.
