No fees. You can ride bikes, just know the trails can have a lot of tree roots so are not smooth. Yield to wildlife. You can encounter gators of all sizes, you can wait for them to move out or turn around.
At least 1 of the trails is designed to accommodate bicycles. My most recent visit I watched a family of 2 small children (<10yr.s) and Mom & Dad riding. It's not built for speed but gentle riding.
