The 28-acre Charles Pinckney National Historic Site preserves a portion of Snee Farm, the plantation owned by Charles Pinckney (1757-1824), a man who was deeply involved in the writing of the U.S. Constitution, as well as a signer of the finished document. The site also addresses the life of African Americans in South Carolina's Lowcountry plantations. The visitor's center is housed in a circa 1838 residence. Note that it is not typical of architecture with which Pinckney would have been familiar.

The site offers a half-mile trail with wayside exhibits, a 20-minute orientation video, exhibits, educational programs, Junior Ranger activities, and a picnic site. Advance notice is required for educational programs. The website offers a teacher's guide, which includes content relevant to the Pinckney site, as well as Fort Sumter and Fort Moultrie.
