John C. Land III Boat Ramp is a premier public access point on Lake Marion featuring six launch lanes, four courtesy docks, and paved parking for 170 vehicles and trailers, plus an additional 200-space lot for the adjacent boating event area.

The facility includes a floating event dock, shelter, restrooms, and concession area, making it well-suited for both casual boaters and organized events.

Located 6 miles southeast of Summerton at the end of Greenall Road in Clarendon County, this is one of the most developed and accessible boat ramps on Lake Marion.
