10am-4pm

Clayton County Conservation is excited to announce the launch of Osborne Days, a newly reimagined fall festival set to take place October 10–11, 2026, at Osborne Park.

Formerly known as Heritage Days, the redesigned event uses input from past participants and staff to better reflect the interests and spirit of the community. Osborne Days will celebrate conservation, creativity, and the fall season through a vibrant mix of local vendors, hands-on activities, and interactive demonstrations.

The two-day festival will feature a wide range of engaging activities and demonstrations for all ages. Planned experiences include outdoor recreation demonstrations such as geocaching, hiking, trapping, as well as conservation education, environmental awareness activities, hands-on workshops, and family-friendly interactive booths. These elements are designed to encourage participation, learning, and a deeper appreciation for local natural resources.

In addition, this event includes a curated marketplace showcasing high-quality, locally made and handmade goods. Attendees can expect a variety of artisanal foods, crafts, artwork, home décor, and other unique items created by talented regional makers. The Osborne Days marketplace will support small businesses while creating a dynamic shopping experience centered on originality and craftsmanship.

Osborne Days will run from 10:00 a.m. to 4:00 p.m. Saturday and Sunday.

Sunday, Oct. 11th will be the Biggest Pumpkin and Best Decorated Pumpkin Contests. Biggest pumpkin participants can begin bringing in their entries at 10am-12:30pm with a weight ticket. The pumpkins will be displayed in the park and judged at 1:00pm. The decorated pumpkins can also arrive on Sunday between 10-11:30am to be displayed to the public and be judged at 1:00pm.
