Campgrounds near St. Ann, Missouri primarily cluster along major waterways and state parks within a 30-minute drive of the city. St. Peters' 370 Lakeside Park offers full-hookup RV sites, tent camping areas, and cabin accommodations with lakefront views, while Cahokia RV Parque provides both RV and cabin options just across the Mississippi River in Illinois. The camping landscape includes a mix of city-managed recreation areas, state parks like Dr. Edmund A.

Many campgrounds in the St. Ann area experience seasonal flooding issues, particularly those near the Missouri and Mississippi Rivers. St. Peters' 370 Lakeside Park was closed for much of summer 2019 due to flooding, though the city has since improved drainage and facilities. Most developed campgrounds require reservations, especially during summer weekends when sites fill quickly. The region's proximity to St. Louis International Airport means some campgrounds experience aircraft noise, particularly those in St. Charles County. Railroad noise affects several sites as well, with one camper noting: "It is near a highway, there's a railroad bridge right next to it, and it is under the airport flight path. The planes and trains stopped after about 10-11pm I think."

The Katy Trail provides a popular cycling route accessible from several campgrounds, including Sundermeier RV Park where "you can literally be parked right at the Katy Trail." Urban campgrounds like Cahokia RV Parque receive positive reviews for their proximity to downtown St. Louis, with one visitor noting it's "a centrally located campground in the Metro St. Louis area... close to interstates and a short drive across the river to Missouri attractions." Most mixed-use campgrounds provide concrete pads for RVs, while tent camping is more limited, primarily available at state parks like Dr. Edmund A. Babler Memorial State Park where sites are described as "quiet and spacious" despite proximity to the metropolitan area.

GuidePlenty of space between spots. Not a lot of flat spots, though. Off-season pit toilet was available. Campground has shower house in-season. Nice and quiet. There was no host but a ranger came around.
LegendVery well maintained. Everything looks new, works well, is clean and organized. Nicest thing is the park is quiet. No road noise which is wonderful. Winter stop for me so I have only seen the shower house from the outside but I would expect it to also be well maintained.
GuideWe only booked 1 night. Location was great but we had to make lot spaces a few times due to the uneven conditions of the lot spaces. Fortunately there was a nice gentleman who worked here and found a space that suited us better. The sites to the back are much better than the ones to the front! The view of the Arch is amazing but a little sketchy … especially at night! But it worked for the night!
TravelerI've stayed here a couple times and generally like the park. I appreciate owners investing in urban RV parks and I don't expect much for amenities in these kinds of settings. The staff were pleasant on a pre-arrival phone call and at check-in—but once there was an issue, the office staff member became very argumentative and rude, consistent with other online reviews.
ELECTRICAL SAFETY WARNING DO NOT use the 30A receptacles here unless you have a surge protector with an Electrical Management System (EMS) that explicitly confirms correct wiring before connecting your RV. My equipment detected a Line/Neutral Reversal on some 30A receptacles; the 50A receptacles appeared to be wired correctly.
When I reported this life-safety hazard, the staffer’s response was, “Don’t use your surge protector—they’re not compatible with our system.” As a licensed Electrical Engineer with 30+ years of experience, I can state that this is 100% nonsense. The surge protector was correctly doing its job by flagging a major wiring fault. Do not follow the staff's advice when they tell you not to use your surge protector to "make it work." That is irresponsible advice that is literally endangering your safety.
The staff also insisted that they don't have a problem because previous 30A users without surge protectors had “no problems.” This is plausible because a Line/Neutral reversal doesn’t usually affect RV operation but the statement shows their complete lack of understanding of the actual problem.
A Line/Neutral reversal energizes the neutral side of the RV's electrical system. This means the RV chassis, appliance housings, and internal neutrals, which should be near ground potential, all become live, creating a serious shock or electrocution hazard if someone touches those RV components while grounded.
The sites are basic with level concrete pads in good condition and other utilities (water/sewer) were fine. Excellent location near the historic St. Charles district. WiFi is unusable—bring your own Internet source. Restrooms and showers are dated and not in great condition. There was also no hand soap at the bathroom sinks all weekend.
This park should be a 7/10 rating, but the electrical hazard drops it to a 5/10. The staff bring the rating down further to a 3/10.
GuideVery nice park. This is a big busy campground they have plenty of staff to handle the rush. Level concrete sites with FHU will definitely stay here again
