Mesker Park Zoo and Botanic Garden is offering free admission to the zoo this Memorial Day for members of our armed forces. Whether you are active duty, retired, a veteran or in the National Guard or reserves, you will receive a free admission to the zoo when you present your military ID at the front gate. The offer only applies to the service member and does not include admission for other members of your party. This is Mesker Park Zoo's way of saying, "thank you for your service." In addition to Memorial day, the offer also is valid on 4th of July and Veteran's Day as well.
