Camping near O'Fallon, Illinois
O'Fallon sits in the Metro East, roughly 20 miles east of downtown St. Louis in St. Clair County. RV travelers use the area as a base for the Gateway Arch, Cahokia Mounds, and Scott Air Force Base, while staying on the Illinois side of the Mississippi where campgrounds are more plentiful and highways less congested.
Options range from a full-hookup urban park at DraftKings at Casino Queen RV Park in East St. Louis, to Safari RV Park in nearby Fairmont City, to primitive state park camping at Horseshoe Lake State Park in Madison County. American Legion Freedom Farm offers a small community-run option close to town, and the St. Louis NE/I-270/Granite City KOA Journey provides a standard KOA experience just off Interstate 270.
The terrain is flat Mississippi River bottomland, and most parks are within a 20 to 30 minute drive of O'Fallon. Sites suitable for larger rigs are common at the private parks, but shade and privacy vary widely between the urban and rural options.
Things to do near O'Fallon
Downtown St. Louis is the main draw. From DraftKings at Casino Queen RV Park, the Gateway Arch, Busch Stadium, and the riverfront are a short drive, MetroLink ride, or bike ride across the Mississippi. Cahokia Mounds State Historic Site, a UNESCO World Heritage pre-Columbian city, sits minutes from Safari RV Park and Horseshoe Lake.
Horseshoe Lake State Park covers roughly 3,000 acres with a 1,200-acre lake, and offers hiking, biking, boating, canoeing, kayaking, fishing, picnicking and wildlife viewing. Numerous hunting programs run from September through February.
Families often pair a day in the city with a lake afternoon, a Cardinals game, or the Saint Louis Zoo and Forest Park museums, which are free to enter.

Summer is hot and humid, with July highs averaging in the upper 80s Fahrenheit and heat index values often higher. Shade matters: the urban parks near the river run hotter and offer little tree cover, while Horseshoe Lake and the KOA Journey have more mature trees. Fall, from mid-September through October, delivers the most comfortable camping weather and lower humidity.
Horseshoe Lake State Park's campground is open from May 1 to September 30, with a maximum stay of 7 days in a 30-day period. Private parks such as DraftKings at Casino Queen and Safari RV Park operate year-round, making them the practical choice for winter or shoulder-season trips.
