Where do you want to go? And when?
If you want to hunt hogs on WMAs, you'll only be able to hunt them from April1-May1 (turkey season), Sept 15- Jan 1 (deer season), and some special hog still hunting on select WMAs in March. This year it was March 2-7.
You can hunt them from Jan 1- March 1 (small game season), but you can't use broad heads, which pretty much means you can't hunt them with a bow.
As to locations, there are several good areas. Woodbury, Wee Tee, and Manchester probably will give you the highest chance of success, but there are plenty of hogs in the Francis Marion and in Sumter National Forest in Abbeville County. All of these WMAs have places to camp. Most of the time, I just sleep in the back of my truck.
