Campsites near O'Fallon, Missouri sit within the rolling hills and wooded terrain of eastern Missouri's transitional zone between prairie and forest. Located at approximately 500-600 feet elevation, this region experiences seasonal temperature variations with summer highs regularly reaching 90°F and winter lows dropping below freezing. Most tent camping areas in this region have compacted soil with moderate drainage, requiring campers to stake tents securely during spring rainfall.
What to do
Bike the Katy Trail: St. Charles County Klondike Park provides direct access to the Katy Trail with multiple access points. "This is a St. Charles County Park and it is well maintained. They also have small cabins though pretty basic. Make sure to store your food securely overnight - the racoons are pretty thick and hungry at night," notes Mike L., who recommends St. Charles County Klondike Park for bikepackers.
Fish at stocked lakes: Several campgrounds maintain fishing ponds with regular stocking schedules. At St. Peters' 370 Lakeside Park, the man-made lake supports various fish species. As Ernest G. describes, "Beautiful area next to a man-made lake. Concrete pads with full hookups, as well as dirt pads with full hookups."
Visit local wineries: Beyond the Trail RV Park places campers within walking distance of multiple vineyards in Missouri wine country. "This is a very nice park. It is located in a sleepy little winery town. It is just a few minutes from the main part of town with multiple beautiful wineries within a few miles," shares Jamie C., highlighting the convenience for wine enthusiasts.
What campers like
24-hour security presence: Several campers mention feeling secure at larger facilities. At Cuivre River State Park Campground, Maria E. shares, "Campground is beautiful and very woodsy. We saw bunnies hopping around and when we first arrived to our site a deer was grazing nearby, such a bonus! No electricity but water was conveniently located right across from our site."
Accessible facilities: Newer campgrounds typically offer well-maintained shower facilities. At Dr. Edmund A. Babler Memorial State Park Campground, Lahree C. reports, "This is truly a hidden gem. Tucked away, not far from St. Louis, you wouldn't know you were that close to a big city. It is clean and feels extremely safe. There aren't many sites, but the ones they have are quiet and spacious."
Family amenities: Multiple camping areas feature playgrounds and recreational rentals. Tom B. at St. Louis West / Historic Route 66 KOA reports, "There is a pool, bike rentals, dog park, movie night, basketball court, and more. You can bring your RV, travel trailer, tent camp, or stay in a cabin."
What you should know
Train noise considerations: Several campgrounds near O'Fallon are within earshot of active rail lines. At Sundermeier RV Park, Jack G. notes, "On Lambert international airports flight path, next to a major train trestle, right next to Highway 370." Laura M. adds, "Only downside is the train and airplane noise. Otherwise would be a 5 star for me."

Tips for camping with families
Trail difficulty ratings: Review trail maps before hiking with children as some paths have challenging sections. At Cuivre River State Park, Chad K. advises, "Cuivre river is about an hour outside St. Louis and offers a multitude of outdoor options from hiking, biking, boating and fishing. The trails are fantastic and have different levels for all."
Designated tent camping sections: Some campgrounds separate tent and RV camping areas. Rick I. shares about Cherokee Lakes Campground: "The host showed me the tent campsites, which are secluded and private from the RV sites. The sites are outfitted with a picnic table and brick fire rings."

Tips from RVers
Pad dimensions: Concrete pad widths vary significantly between campgrounds. Suzie S. notes at St. Peters' 370 Lakeside Park: "The nicest spots are the ones by the lake, with only one neighbor and a better view of the lake. The staff are kind and helpful. Water and electric worked fine. Each site has a fire pit and picnic table."
Leveling requirements: Sites at older campgrounds often require leveling equipment. Michael M. shares about Pere Marquette State Park Campground: "The campground has 88 sites total 1-85 are either 30 amp or 50 amp electric sites. These are the class A sites $20 a night, they also have about 15 Class C sites for tents with no electric for $8 a night."
Service placement considerations: At some campgrounds, utilities are positioned inconveniently. Craig H. observes about Beyond the Trail RV Park: "The site services, electric, water and sewer, are located to the front of the site and extensions were needed for both the electric and sewer."
