Welcome to Boone County Arboretum,
"Where fun and family take root."

Child Smelling Flower

There are few places in the Greater Cincinnati, Northern Kentucky area where you can see such a unique arrangement of diverse plants. Encompassing 121 acres, the Boone County Arboretum is also known as Central Park, and was the nation’s first arboretum within an active recreation park setting. The specialized arrangements of plant families and 12 athletic fields are connected by a 2+ mile winding multi-use trail. Don't let the inclusion of sports throw you off though - the beauty and educational value of these plant collections, including obscure selections rarely observed by the public eye, will captivate everyone from the avid plantsman to the average homeowner. The Arboretum is Accredited at Level IV (the highest level) by the Arbnet Accreditation Program, a recognition held by very few other arboreta in the region. Pets are welcome in most areas of the Arboretum, as long as they are on a leash and picked up after.

Boxwood Collection Area

Boone County Arboretum is located just outside Union, KY, only 25 minutes southwest from downtown Cincinnati. We are open daily from 7:30am to dusk for your year-round enjoyment of our more than 3,600 trees and shrubs. There is no charge for admission or parking.

Throughout the year we offer various classes and programs for all age groups. In addition, many of the Boone County Extension horticulture classes are taught here at the Arboretum. To learn more about our facility, special attractions, history, and future plans, visit our "about us" page.
