Go on line and see what you can find, there is only one state park south of Ft Myers that has camping.(Koreshan), the state parks run about 26-28 a night. In winter thousands of snow birds flock to Fl. all the cheaper camp grounds are filled up by reservation. This has been our experience, the ones in north FL. are cold in winter, and empty. We like camping along route 41 and south of there because you can fine a camping spot, they are cheap and it is warm. Dec,Jan, Feb,and most of March are the busiest months. There may be county parks in the area also. We have books for National, Corps and State parks in FL.
