The Zoological District, made up of Jackson and Clay counties, supports the Zoo through a 1/8th cent sales tax As a thank you, Zoological District residents receive the following benefits that include four free admission days throughout the year with the Postcard to Adventure program. Residents should have just received a postcard good for free admission on any day in November or December. Each postcard is good for two adults plus your dependent children living in the same household. Due to the pandemic, the Zoo is currently using timed reservations but this will have no cost associated due to your postcard. To make your reservation, please click the appropriate link below.
