Silver Springs is nice and sites are sufficiently large . Another thought is E.G. Simmons County park in Ruskin. It's on Tampa Bay, most sites are canal front. A bit further south ( 60 miles) is Venice Campground, on the Myakka River. Closer to Tampa, is Hillsborough River State Park . Sites 19,20,21,22,23,36,37c,51a,60,71,72 are large with easy access. Lithia Springs County park is also close by , Suggest sites 1,3,4,27,32,40 as the best, with 2,5,6,7,9,10,13,14,15,36 as other roomy sites.
