Sesquicentennial State Park, known as Sesqui, is a South Carolina state park in the Sandhills near Columbia, combining pine uplands with a 30-acre lake that anchors much of its recreation. It originated in Columbia’s 1936 sesquicentennial celebration, when surplus funds helped purchase the land in 1937 before it was transferred to the Commission of Forestry. Civilian Conservation Corps Company #4469 developed many of the early structures and the stone entrance, leaving the park with a distinct New Deal-era character. Today it remains a major outdoor destination, offering camping, boating, fishing, hiking, mountain biking, a splash pad, and a dog park.
