If you can't get in there try Crystal River and/or Rainbow Springs Park area CG's, Rock Crusher always get 'great' reviews here on the forum as there are quite a few other than the State Parks. There's Goethe State Park, and Rainbow Springs State Park if that is what you want though too.
Beautiful bright blue crystal clear natural springs at Rainbow and see the manatees in Crystal river.
IMHO all in this are are MUCH nicer places than ocala National Forest and they are all within 20 minutes of Ocala. And if you like great seafood by the shore,Charlie's in Crystal river should not be missed! :C
