Re: Camping / Boating GA, AL, TN ???
Floating Mill Park campground on Center Hill Lake, TN is nice. Its not far off I40, has a nice launch ramp, supper nice people working the entrance, tent, pop up, and rv camping on the lake, a nice playground, and centrally located on the lake. You have a nice marina a short distance away (Hurricane Marina) with a nice restaurant. You can explore the lake two different directions, with plenty of long and deep coves. Depending on when you go, you can even boat all the way to a waterfall.
If you don't want to tent camp, the cabins at Tims Ford marina are real nice and reasonable. The people and food at the marina are both great. Tim Ford, unlike Center Hill, has houses on it, though. So if you enjoy cruising around and looking at lake houses, go there. If you prefer isolated coves and trees, go to Center Hill.
