Another visitor adds, "The park/campground rents paddleboats, kayaks, and canoes in addition to different kinds of bikes."

Another reviewer mentions that "Close to the arch, that's why we chose this place to stay overnight."
What campers like
Budget-friendly options: Some campgrounds offer affordable rates compared to urban accommodations. Horseshoe Lake State Park Campground stands out with its $8 nightly fee. As Travis notes, "Self service pay system makes it simple, easy, and fast. Camping can be reserved but no need. Just pick your spot go to the office building, and fill out the form, pay and slide in envelope and drop in box."
Privacy between sites: Despite being near urban areas, certain campgrounds offer reasonable spacing. At Cahokia RV Parque, Laura M. observed that "The campsites were a little close together and there were a lot of campers," yet other locations like Horseshoe Lake provide more seclusion, with one camper noting, "The campground is relatively small but has great sites to camp. Very private and clean."
On-site amenities: Several campgrounds feature unexpected conveniences. "The nice thing is the campground is staffed by rangers in the day, and at night they sometimes take a security swing through the campground," mentions one visitor about Horseshoe Lake. At Cahokia RV Parque, a visitor highlighted the "Great BBQ restaurant onsite," adding "While we prepare most of our meals, we were so tired; we decided to give the joint a try and, wow, are we glad we did!"
What you should know
Noise considerations: Urban proximity means noise is common at several campgrounds. At St. Louis NE-Granite City KOA, Jennifer B. reports, "Yes, trains pass 2 blocks away several times nightly, but after the first night you won't notice. During modified car racing season, Friday nights are roaring loud from the racetrack nearby." Another camper noted, "A train honked early in the morning."
Industrial settings: Many campgrounds are situated in commercial or industrial areas. One Casino Queen RV Park visitor described it as "Full hookup sites on a mostly paved RV park. Big rigs fit easily. Some small areas of grass and trees with a dog walking area around the perimeter... The park is in an industrial area so you can hear trains occasionally as well as the METRA rail."
Flooding risk: Low elevation makes some campgrounds vulnerable to seasonal flooding. A St. Peters' 370 Lakeside Park camper observed, "One of the downsides to this location is that it is prone to flooding... the City of St Peters did a great job getting this place back to usable with new sod, a new bathhouse, and some general sprucing up."
Tips for camping with families
Playground access: Several locations offer dedicated play areas for children. At St. Louis NE-Granite City KOA, one camper shared, "The playground and bounce pad and store were closed due to coronavirus, but the bathrooms and showers were open." Another visitor highlighted that their "kids loved the jumping pillow at the park."
Wildlife viewing: Wildlife spotting opportunities exist even near urban settings. At Scott AFB FamCamp, visitors appreciate the natural surroundings despite the military base location. "The nearby lake is scenic and peaceful," notes one reviewer. At St. Peters' 370 Lakeside Park, a camper mentioned, "You can see all kinds of wildlife in and around the lake- deer, bald eagles, pelicans, ducks, snakes."
Security considerations: Many campgrounds feature 24-hour security or regular patrols. At Casino Queen RV Park, a reviewer noted, "Security rolled through frequently. Your gate code can be used for the pool and gym at the casino in addition to the bathroom and laundry area." This provides families additional peace of mind when camping near urban areas.
Tips from RVers
Site surface quality: RV sites vary in construction and levelness. At St. Louis NE-Granite City KOA, James P. observed, "Sites are mostly level," while at Cahokia RV Parque, a visitor mentioned, "We stayed in a gravel site with a concrete pad, fire pit, picnic table and full-hook ups."
Reservation protocols: Some campgrounds require specific reservation procedures. At Casino Queen RV Park, Josh F. noted, "Park is not staffed, you get a gate code in your email to access the park," while another reviewer added, "You need a code to get in the gate, so you must register in advance."
Access challenges: Some campgrounds have tricky entrance approaches. One visitor to St. Louis NE-Granite City KOA warned, "A little sketchy getting off east bound ramp then having to cross three lanes of traffic to make a left hand turn at the first light. Entrance to campground is tight, swing wide."
