Google FWMD, that's Florida Water Management District. On their website search for Hickory Hammock camping. It will most likely show up as an equestrian campground, but there both the same. This is a pretty nice place with good we'll water available and the best part is it's free.
Let me know how the hike trail is. If it needs attention. I am the maintainer in charge.
https://secure.rzda.net/sfwmd/list.cfm that's the direct link to the list where you select hickory hammock. You'll have to create an account then look to see if the dates you want are available. I've only done a day pass there but I will be camping first weekend of March. Once you request the dates you'll get a confirmation email and the gate code will come in a separate email as your camping date gets closer.
BKG answered and yes it's a nice place to getaway, best time of the year for me January-March.
