"The campsites are in the middle of the city park and it was nice to be able to walk our dogs around the park after a day of traveling. We had full hook ups which is always a relief!!"
"The prices are incredible, and you can even do your laundry for free! I would recommend this to anyone looking for a quiet, beautiful, and affordable place to get away."
ScoutIt’s fun to see the animals. I was happy they have an outdoor shower because I needed it when I got here. I’d say the only down side is the animals roam so there is a lot of poop. Wouldn’t want to wander at night.
ScoutPretty dirty from last people. Toilet paper everywhere. But it’s a quiet place to park for the night. Not recommending anything more than parking for the night.
ScoutMy favorite spot in all of St. Louis! The lady who is the owner and the front desk attendant are wonderful and I have never had a problem here with anything! Free WiFi, laundry, and a public shower and bathroom if needed! There’s also cool walking/biking trails and a park with a children’s playground as well! The gas station is also walking distance for any small necessities
TravelerStaying in tent area with campervan. 26 dollars a night. Good spot. You do hear the highway a bit. Hosts are friendly and helpful. Bathhouse is basic but does the job.
GuideGraham Cave State Park could be a lovely campground but is in dire need of updating everything. The campsites are very uneven and the bathhouses are partially working. The campground host, however, was very friendly and diligent. The trails were well kept but unfortunately it was so dry the river was very low.
GuideHardly anyone here. On a Tuesday in October. Took a primitive site. Reasonable. Fairly quiet. Some ambient noise from i70
GuideIt appears to be a typical state park. There are lots of old trees. Sites are pretty close together but it is late October so it is not crowded. Each spot has a level gravel spot, electrical hook up (some are 50 and others 30 and ours had a 110 plug in which is what we needed, as well as a picnic table, and a fire pit. There are both pit toilets and a large building that has flush toilets and showers. Everything is old and would benefit from a refresh but it was all clean enough for camping.
ScoutMy favorite RV spot in St. Charles. It’s pretty quiet minus the cool boats and train but other than that it’s peaceful…also love the price!
GuideThis is a nice, clean, little campground.Free of charge dispersed.No hookups , car pads , fire pits right on the mississippi river , just beautiful , really , really impressed
RV camping options near O'Fallon, Missouri provide convenient access to both urban attractions and rural escapes. The area sits at the convergence of the Missouri and Mississippi Rivers with elevations ranging from 400-600 feet above sea level. Summer temperatures typically reach 85-95°F with high humidity, while spring and fall offer milder conditions ideal for outdoor activities.
Explore Katy Trail access points: Beyond the Trail RV Park offers immediate trail access for cycling enthusiasts. "The Katy trail borders the park for easy access to town. Beautiful views across a large farm field (soy beans when we were here) to the hills beyond with incredible sunsets," notes one visitor to Beyond the Trail RV Park.
Visit local wineries and breweries: Many campgrounds are situated near Missouri's wine country. "There is a really nice brewery right at the entrance. Within walking distance is a really nice winery and a couple bars. All of these places have cold beer and live music on the weekends," shares a camper at Beyond the Trail RV Park.
Enjoy water recreation: St. Peters' 370 Lakeside Park offers lakeside activities including kayaking and paddleboats. "This is a great place to kayak and camp if you don't want to drive that fare and live in the city. We love going here and watching the sunsets," explains a visitor to St. Peters' 370 Lakeside Park.
Visit the Gateway Arch: RV campgrounds on both sides of the Mississippi provide access to St. Louis attractions. "We got site 41 and it was perfect with our 31' travel trailer and we did not have to unhook. Too hot and tired to walk around but there is a park and access to a walking trail that looks nice," shares one traveler at Sundermeier RV Park.
Concrete pads with full hookups: Many rv sites near O'Fallon, Missouri feature level concrete sites. "Very 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," notes one reviewer about Sundermeier RV Park.
Easy access to historic areas: Campgrounds provide convenient access to historic downtowns. "You can literally be parked right at the Katy Trail. Through the gate at the rear of the campground, and you can bike for miles. Easy ride in to St. Charles a wonderful historic river town on the Missouri River," explains a visitor at Sundermeier RV Park.
City park amenities: Hermann City RV Park offers unique municipal park integration. "Spot 36. Full hook up — 30/50 electric, water, sewer. Literally located in the middle of the city park, between the community pool, the soccer fields and the baseball diamond," describes one camper at Hermann City RV Park.
Secure camping options: Gated RV parks provide peace of mind for urban camping. "You need a code to get in the gate, so you must register in advance. It was hot in late July and with no trees on the larger sites, it seemed hotter. But the full hookups worked great with no issues," reports a visitor at Casino Queen RV Park.
Noise considerations: Train and airplane noise affects several campgrounds. "Only downside is the train and airplane noise. Otherwise would be a 5 star for me," notes one camper at Sundermeier RV Park. Similarly, a Casino Queen visitor mentions, "There are trains every 15-30 minutes all day long."
Seasonal flooding concerns: Weather patterns can impact some camping areas. "My only complaint is they have some drainage issues if it rains a lot. A few of the campsites will flood, not bad enough to get to your camper, but just enough to be annoying," cautions a camper at Beyond the Trail RV Park.
Limited shade at newer campgrounds: Many rv parks in the O'Fallon area lack mature trees. "I have to preface my review by saying that this isn't my kind of campground. I like trees and nature around. This park had very little of that. It seems to be new, and there are trees planted, but it will be awhile before they provide any shade," explains a visitor to St. Peters' 370 Lakeside Park.
Campground layouts: Site arrangements vary significantly between parks. "The sites are a bit close together and not many trees but I've been to worse. The not many trees is do to it still being a fairly new campground. The lake is nice and they have some spots close to it," reports a St. Peters' 370 Lakeside Park camper.
Recreation facilities: Look for parks with kid-friendly amenities. "This park is beautiful. Located about 25 minutes from St Louis. They have paddle boats and bikes and group bikes for rental. Located right next to a lake with a lot of RV and tent camping spots. Kids had a blast riding bikes. Even finding a few little frogs jumping around and fireflies at night," shares a family at St. Peters' 370 Lakeside Park.
Urban camping with outdoor access: Cahokia RV Parque combines city convenience with recreation. "They've got great amenities: 30/50amp, water, sewer, wifi, pool, showers, fire rings, and a trash dumpster. They even filled up my LP on site. There's a small site for primitive camping by the pond with a gazebo to fish off of," notes a visitor.
Check for after-hours access: Some campgrounds provide flexible arrival options. "I specifically would like to point out things that I look for when booking because I'm usually already on the road when trying to find a place to stay. There was after hours check in! But also a friendly staff in the office. Beautiful coded bathrooms with showers," reports a Cahokia RV Parque camper.
Consider neighboring recreational opportunities: Look beyond campground boundaries. "The campground is in the city park. The campsites are in the middle of the city park and it was nice to be able to walk our dogs around the park after a day of traveling," notes a visitor to Hermann City RV Park.
Big rig accommodations: Many parks accommodate larger RVs. "For this to be such a small RV park (smallest we've stayed at so far) the sites are very spacious! The wi-fi was surprisingly good enough that my wife and I could both work off of it and even stream shows on the Roku the whole week," explains a camper at Covered Bridge RV Park.
Water pressure considerations: Water systems vary between parks. "Positives: Really nice people at check in. It does have 30 amp service even though this app shows it doesn't. 30 pound water pressure. Nice level concrete pad with a picnic table," notes a Sundermeier RV Park visitor.
Utility placement: Pay attention to hookup locations. "Utilities are set up weird on all sites - Water and electric are at the very rear of the site by the sewer, so you will need a decent sized hose to reach if your water intake is in the front of your camper," warns a visitor to Casino Queen RV Park.
Book ahead during peak seasons: Popular campgrounds fill quickly during events. "This hidden gem is the place to go for Maifest, Octoberfest or any trip to Hermann. If you are going, book early. We visit the area 1 to 2 times per year and book as we leave for the next year," advises a Hermann City RV Park camper.
