Make the Grandparents in your life feel extra special this Grandparent’s Day at the Cincinnati Zoo! All grandparents will get FREE admission on Sunday, Sept. 8th for Grandparents Day presented by Mutual of Omaha. Just let the ticketing staff know you are a grandparent and walk right in! You don’t even need to have your grandkids with you as proof. Be sure to stop by Vine Street Village between 10AM-5PM to participate in a unique photo experience with zoo animals, courtesy of Mutual of Omaha’s Wild Kingdom! Happy Grandparents Day!
