Best campground for Kayak fishing???

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.

EDIT: Sorry - I missed the "intercoastal/bay/ocean" part. My response wasn't of much use to you.
