This beautiful plantation represents the history and culture of Georgia's rice coast. In the early 1800s, William Brailsford of Charleston carved a rice plantation from marshes along the Altamaha River. The plantation and its inhabitants were part of the genteel low-country society that developed during the antebellum period. While many factors made rice cultivation increasingly difficult in the years after the Civil War, the family continued to grow rice until 1913.

Today, at the plantation, a museum features silver from the family collection and a model of Hofwyl-Broadfield during its heyday. A brief film on the plantation's history is shown before visitors walk a short trail to the antebellum home. A guided tour allows visitors to see the home as Ophelia kept it with family heirlooms, 18th- and 19th-century furniture and Cantonese china. As one of the Colonial Coast Birding Trail sites, Hofwyl-Broadfield offers a nature trail that leads back to the Visitors Center along the edge of the marsh where rice once flourished.

The plantation offers exhibits, a film, and tours.
