How to Book a Campsite Near St. Louis
Revised August 17, 2026
What is the best campground near St. Louis?
There isn’t a single best one, and any list that names one is guessing for you. The best campground near St. Louis is whichever one matches three things: what you sleep in, how far ahead you booked, and whether you need a shower. Sort by those and the field narrows fast.
Keep reading ↓Imagine it’s a Wednesday in March and somebody in the group chat types “let’s camp Memorial Day weekend.” Six people react with a thumbs up. Nobody books anything. Then it’s the second week of May, you finally open the reservation site, and every electric site within ninety minutes of Kirkwood is spoken for.
Maybe your version is different. You bought a used travel trailer off a driveway in Florissant over the winter and you still aren’t sure whether the cord coming out the back is 30 amp or 50. Or the kids are seven and four, nobody in the house has ever slept in a tent, and you want a first night out close enough to Affton that bailing at midnight is still an option.
Camping around here is genuinely easy. The booking is where people get burned, because the two states on either side of the river run separate systems, open their calendars at different times, cap your stay differently, and price a night outdoors far enough apart that the bridge is worth crossing.

On the Missouri side, the close ring of state park campgrounds includes Dr. Edmund A. Babler Memorial State Park at 800 Guy Park Drive in Wildwood, Robertsville State Park where the Meramec River and Calvey Creek meet in Franklin County, and Meramec State Park at 115 Meramec Park Drive in Sullivan, which puts Fisher Cave and river access in the same trip. Cuivre River State Park north of Troy and Washington State Park south of De Soto fill out the arc.
Cross the river and the math changes. Pere Marquette State Park in Grafton runs 80 reservable Class A sites with 20, 30 and 50 amp service and a shower building, plus non-reservable Class B tent sites. Eldon Hazlet State Recreation Area on Carlyle Lake is bigger than anything close on the Missouri side: 328 Class A sites with 30 and 50 amp hookups, 36 walk-in Class C tent sites and three shower buildings. Closest of all is Horseshoe Lake State Park in Madison, Illinois — 26 tent or trailer sites, a dump station, pit toilets and water hydrants, open May 1 through September 30, no reservations taken.
How much does it cost to camp at a Missouri state park?
On the 2026 on-season chart, which covers April 1 through October 31, most Missouri state parks charge $15 a night for a basic or walk-in site, $27 for a 30-amp electric site and $29 for 50-amp. Electric and water together runs about $35. A full sewer, electric and water site lands between $42 and $57 depending on the park.
Backcountry sites are $10. A few parks sit below the common rate — Echo Bluff starts at $13 basic, St. Joe at $12 — and a few sit a dollar or two above. Off-season, November 1 through March 31, the same tiers drop to roughly $14 basic, $23 for 30 amp and $25 for 50 amp.
Add the booking cost on top. Missouri charges $6.50 per campsite reserved online, $8 through the call center at 877-422-6766, $5.25 to change a reservation and $10 to cancel one, with the original reservation fee forfeited either way. A $2 per night discount applies year-round for campers 65 and older, people with disabilities, and current, former and active-duty military families.
How far ahead do campsite reservations open?
Missouri opens 12 months out. Illinois opens six. That one difference decides more summer weekends than anything else on this page. Missouri State Parks takes reservations starting at 7 a.m. Central Time exactly one year before your first night, so a Memorial Day site is claimable the previous May.
Illinois DNR releases sites 180 days ahead through ExploreMoreIL, also at 7 a.m. Central. Illinois also refuses last-minute bookings: a reservation has to be made at least three days before you need the site. Missouri goes the other direction and accepts same-day reservations up to 7 p.m. on your arrival date, with no reservation fee charged on those.
Length of stay is capped on both sides. Missouri limits you to any 15 days within a 30-consecutive-day period at one park under 10 CSR 90-2.030. Illinois caps reservations at 14 nights per 30-day period, and Horseshoe Lake tightens that to seven days in 30. The Illinois reservation fee is $5, non-refundable, and camping fees are refunded if you cancel three days out.
What does a campsite fee actually include?
A basic Missouri state park site buys you a parking pad, a table, a grill and a lantern post. That is the whole list. Electric adds a 30- or 50-amp power supply, electric and water adds a private water hookup, and the top tier adds a sewer connection. Everything else — shelter, bedding, light, water containers, a way to cook — comes out of your car.
Illinois builds the fee the same way but shows the math on the receipt. Its published schedule splits each night into a camping fee plus a $10 utility fee, so a Class A site with showers, electricity and vehicle access is $10 plus $10, or $20 a night. Class B/E, electricity and vehicle access without showers, is $18. Class B/S, showers without electricity, is $10. Class C is $8 and Class D primitive tent sites are $6. Holiday weekends push Class A to $30.
Neither state charges you to drive through the gate. Illinois DNR says outright that it “does not charge an Entrance Fee to any state owned or operated land.” Missouri funds about three-fourths of its state park budget with the one-tenth of 1% Parks, Soils and Water Sales Tax, which voters renewed in 2026 with roughly 82% approval.
Nothing to do with tents — St. Louis gyms are here too.
Do you need 30 amp or 50 amp, and does water come with it?
Check the cord before you book, not at the pedestal. A 50-amp rig plugged into a 30-amp site through an adapter is still limited to 30 amps, which in a St. Louis August usually means one air conditioner instead of two. Missouri lists more than 1,200 campsites with 50-amp service, and those pedestals carry 30 amp too, so the bigger site fits either rig.
Water is the part newcomers misread. On Missouri electric/water and sewer/electric/water sites, the private hookup runs only during the park’s on-season. Book one of those in February and you have paid for a spigot that isn’t running. Electric hookups, by contrast, stay live year-round at most Missouri parks.
Illinois handles the same problem with a price cut. Its published rule is that when cold weather forces buildings closed and water shut off in Class AA, A, A-P, B/S or B/S-P campgrounds, the fee drops to match what is actually available for use. Call the park office before any winter trip; that is the only reliable way to learn which shower house is open.
What closes for the season, and what stays open?
Most campgrounds within reach of St. Louis stay open all winter at the lower off-season rate. What closes is the plumbing. Missouri’s 2026 off-season chart lists Babler, Robertsville, Meramec, Cuivre River, Hawn, Washington, St. Francois, Onondaga Cave and Graham Cave as available every day of the off-season. The system runs more than 3,500 campsites in all.
Illinois splits its year into a May 1 through September 30 spring and summer period and an October 1 through April 30 fall and winter period, and says camping is generally available year-round, weather permitting. Individual campgrounds are the exception that matters — Horseshoe Lake State Park’s campground runs May 1 to September 30 and nothing else.
Three Missouri parks start early rather than late. Roaring River, Bennett Spring and Montauk open their on-season February 25 because trout season does, and Table Rock runs March through November. None are day trips from the metro, but they answer the March weekend where you want the water actually on.
What does a first-time camper actually need?
Sleep warm, then worry about the rest. Ground pulls heat out of a body far faster than air does, so an insulated sleeping pad does more for an April or October night around here than upgrading your sleeping bag. Add a tent with a full rainfly, two light sources per person, and more water than you think you need — the site’s hydrant may be a walk away, or shut off entirely.
Know the site’s limits before you pack. A typical Missouri state park campsite allows two sleeping units, only one of which can be wheeled, two non-sleeping vehicles and six people. Quiet hours run 10 p.m. to 6 a.m. Check-in starts at 3 p.m., checkout is 2 p.m., and you have to arrive within the first 24 hours of the stay. Leashes are capped at 10 feet, with two dogs per site recommended.
Buy firewood, don’t forage it. Missouri State Parks asks campers not to gather or cut firewood in the parks, so plan on a bundle from the park store or a stand down the road. If you are planning a bigger trip around a camping leg, lock the campsite dates first — those are the ones with a release date you cannot negotiate.
What campground owners around here wish campers knew
A campground makes its year in roughly fourteen weekends. Memorial Day through Labor Day carries the season, a few October leaf weekends help, and a rained-out Fourth of July cannot be made up in November. That is why monthly and seasonal sites exist: they fill Monday through Thursday when transient campers don’t come. A monthly site near $800 works out around $27 a night, well under a summer weekend rate. That trade buys stability, not profit.
The margin lives in the small stuff — firewood, ice, propane, laundry, the store — because the site itself has to cover a septic system, a well, gravel and mowing whether anyone is on it or not. What operators complain about to each other is holiday no-shows and August electric bills, when every rig on the property runs air conditioning at once. Being listed with accurate hookup amperage, pad length and season dates saves both sides that phone call, which is most of why owners keep a complete listing current.
Still deciding where to point the car? Browse campgrounds across the St. Louis metro on St Louis Near Me Directory, then call the one you like and ask two things: what amperage the site carries, and whether the water is on the weekend you want.

Frequently asked questions
What is the 200 rule for camping?
It’s the Leave No Trace guideline to camp at least 200 feet from lakes and streams — described as 70 to 80 adult steps — so riparian ground stays intact and wildlife keeps its access routes to water. The same buffer applies to washing dishes and burying waste. It governs backcountry and dispersed camping, not developed campgrounds, where you pitch on the pad the park assigns you.
What is the 3-3-3 rule for camping?
It’s an RV travelers’ rule of thumb, not a regulation anybody enforces: drive no more than 300 miles in a day, be parked by 3 p.m., and stay at least three nights before moving again. The enforceable limits are different. Missouri caps camping at any 15 days within 30 consecutive days at one park, and Illinois caps reservations at 14 nights per 30-day period.
Are there any free campgrounds near St. Louis, Missouri?
Not inside the metro. The closest genuinely free option is dispersed camping in Mark Twain National Forest, where you camp outside any developed campground with no fee and no permit required, typically for up to 14 days in a 30-day span. The nearest ground is the Potosi/Fredericktown Ranger District south of the metro. There is no pad, no toilet and no water, so check the district’s motor vehicle use map first.
What is the cheapest campground?
Among developed sites near St. Louis, Illinois undercuts Missouri. A Class D primitive tent site on Illinois DNR land is $6 a night and a Class C site with vehicle access is $8, against $15 for a typical Missouri basic site and $10 for a Missouri backcountry site. Add $5 to reserve in Illinois or $6.50 online in Missouri. Free means dispersed national forest camping, with nothing provided.
How much do campsites cost per week?
Public parks don’t discount by the week — it’s the nightly rate times seven, plus one reservation fee. Seven nights on a Missouri 30-amp electric site works out to about $189 plus $6.50 online. Seven nights on an Illinois Class A site is about $140 plus $5. Private RV parks around the metro do post weekly rates, commonly between $175 and $375 depending on hookups, as advertised in August 2026.
How much do most campgrounds cost per month?
Around $800 a month for a full-hookup site at a private RV park in the St. Louis area, checked in August 2026, with electricity often metered separately on top. Public campgrounds are not an option for monthly stays at all: Missouri state parks cap you at 15 days in any 30, and Illinois caps reservations at 14 nights per 30-day period.
Can I just show up, or do I have to reserve?
It depends on which side of the river. Missouri State Parks accepts same-day reservations up to 7 p.m. on your arrival date and waives the reservation fee on those. Illinois requires bookings at least three days ahead, so a spur-of-the-moment Illinois trip means a first-come campground — Horseshoe Lake State Park in Madison takes no camping reservations at all, May 1 through September 30.
