Cohutta is right on the Tennessee border and is the largest WMA East of the Mississippi at just under 100,000 acres and is mostly connected to the Chattahoochee National Forest of 750,000 acres. It is VERY rugged and I have done a ton of solo backpack hunts there over the years. You will need a Georgia hunting license, big game license and a WMA stamp.
Quality of bear hunting there is very, very much tied to mast production. In years where acorn are very sparse you will find bears if you can find the acorns. In years with a heavy mast crop, finding a bear is like looking for a needle in five hay stacks as the bears are dispersed over huge areas and will stay in the thick laurel thickets to feed. A GPS is critical for finding acorns at specific elevations in sparse mast years as sometimes the acorns will be at a narrow band of say, 200' wide.
If you are hunting the cowpens or tear britches areas, get in the best shape of your life. One of my most vivid memories of Cohutta was climbing a steep mountain and being able to touch the ground without bending at the waist one bit- no joke.
Good luck on your hunt.
