If you plan on sticking around for brunch Saturday morning, consider checking out the Sage Garden Cafe near downtown Frankfort! Afterwards, meander through the expansive Wilson's Nurseries just next-door and explore the Butterfly Greenhouse and Lola Children's Garden (see https://www.thebutterflygreenhouse.com for event and ticket info).
Check out the botanical gardens adjacent to Buffalo Trace Distillery.
Stop by for a free tasting and check out the gift shop, or schedule a tour online! Note: The basic tours are free and, therefore, difficult to book. Apply to join the waitlist as far in advance as possible as time slots do often become available closer to the date.
While you're in Kentucky's state capitol, why not check out the capitol building! The building is open to visitors during the day with valid ID and tours can be scheduled ahead of time. Refer to the website for more info. There is also a giant floral clock located on the grounds decorated seasonally!
