The Green Swamp starts about 16 miles north of Lakeland, and Colt Creek State Park is the piece of it you can sleep in. The campground sits back in pine flatwoods off SR 471, far enough out that the loudest thing after dark is frogs. Get the pad before you get the van. There are 27 full-facility sites, which is what a Polk County trip has to be built around, and the van is the second booking.
Pine flatwoods means slash pine over saw palmetto, flat ground, and long sightlines between the trunks. It goes quiet out there in a way the coast never manages.
Inland Florida runs hot and wet through the summer, and the swamp is where the afternoon storms stack up, so the cool half of the year is when the drive north pays for itself. It is also the half of the year worth booking early for.
It is a small campground and it is set up for vehicles rather than backpacks. There are 27 full-facility sites plus six tent-only sites, every one of them wired for 30- and 50-amp, and some pads will take a rig up to 70 feet, so a van fits with room left over. The dump station is at the campground entrance rather than at the pad, which means you empty on the way out instead of when you arrive (Florida State Parks, as of August 2026).
The reservation window opens 11 months out through Florida State Parks, and it is a full-facility pad you want. The six tent-only sites are a separate reservation and they are not for a vehicle, so one of those is not a van night. There is no in-town substitute if it falls through either, since Saddle Creek does not take a camper van as a camping unit and Circle B is a day out.
One rule changes how you spend the evening. The park has been under a burn ban since Feb. 17, 2026, and it covers open fires, campfires, and cooking fires alike, so nobody is building anything in a ring. A site runs $24 a night plus tax, with a nonrefundable $6.70 reservation fee and a $7 nightly utility charge on RV units (Florida State Parks, as of August 2026).
Saddle Creek Park and the Polk County camper van rule
Saddle Creek Park is the in-town option, 750 acres of county land on Morgan Combee Road on the east side of Lakeland. It has 36 sites for vehicles on partial hookups, water and 20/30/50-amp power, plus showers, flush restrooms, a dump station, and five primitive sites for tents. Water and electric are $20 a day (Polk County, as of August 2026).
Read the county's rules before you build a night around it. Polk County's campground policy says camper vans and passenger vans are not recognized as camping units, and anything staying has to be state-registered with a visible sticker (Polk County, as of August 2026). Fires are not permitted at Saddle Creek either.
That rule is the whole reason Colt Creek gets the recommendation. The county publishes online reservations and also says its campgrounds are first-come, first-served, so if you do want the in-town night, call first and get somebody to tell you yes about your specific vehicle. Turning up at dusk to argue about what counts as an RV is a bad end to a driving day.
Circle B Bar Reserve is the day out from either campground, south of downtown on Winter Lake Road. Alligators and birds off the shoreline and the pier, a Nature Discovery Center on site, and no camping of any kind, so treat it as a stop and not a night (Southwest Florida Water Management District, as of August 2026).
Lake Kissimmee, and the parks east and north
Lake Kissimmee State Park, east of Lakeland, is the one to cross off the list for now. Its campgrounds closed for a renovation project effective Feb. 17, 2026, and no reopening date has been posted (Florida State Parks, as of August 2026). Old itineraries still send people out there to sleep, and the drive is long enough that you want to know before you commit to it.
For springs and the bigger state-park campgrounds, keep driving. Orlando and Clermont cover the parks on the far side of the county line, and Ocala is the run north toward the national forest. The Florida hub has the rest of the state, coast to coast.
