Any of the Corps campgrounds or state parks on either side (GA or SC) of Clarks Hill Lake NW of Augusta, GA, are great places to camp and fish from a kayak. If you're active or retired military, there's even a very nice Army resort with multiple camping areas, a marina, etc., called Pointes West on the Georgia side.
