How to get to Barnwell State Park

The park sits off SC Highway 3 near Blackville, roughly a 50 mile drive east of Augusta, Georgia, and about 70 miles south of Columbia, South Carolina, with each leg taking around an hour. Charleston is about 110 miles southeast, roughly a two hour drive. Access roads are flat rural highways with no mountain passes or tunnels, so large Class A motorhomes and travel trailers can reach the park without major grade concerns, though drivers should watch for low-hanging trees on narrow county roads. The nearest major airport for fly-and-rent trips is Augusta Regional Airport (AGS), with Columbia Metropolitan (CAE) as a larger alternative.
