Public land it sits in

On Wilderness Atlas →

National Forests in North Carolina begins about 14 miles away, and it is the closest of these.

Each unit is published as a centre point and an acreage rather than a boundary, so this section stands it in for a circle of the same area. Whether a campground is inside, and how far it is from one it is outside, are both approximate.

Natural features

Hartwell Lake is a man-made lake bordering Georgia and South Carolina on the Savannah, Tugaloo and Seneca Rivers. The dam and lake area boasts 8 campgrounds and 11 day-use facilities that are operated by the US Army Corps of Engineers. The Hartwell Project was originally authorized for hydro-power, flood control, and navigation. Later, recreation, water quality, water supply and fish and wildlife management were added. Surrounding vegetation allows for plenty of shade, and the 962 miles of shoreline provide numerous swimming beaches, picnic areas and boat ramps.

Recreation

Boating and water sports top the list of popular activities. A boat ramp is provided for easy lake access. With multiple trails snaking throughout the shoreline area, hiking and biking are also popular pastimes.
