    Several RV parks surround Union, Missouri, offering convenient access to both I-44 and the Meramec River region. Birch Creek RV Park, located just 20 minutes from Meramec Caverns, provides full hookups with concrete pads and both 30 and 50-amp electrical service. Pin Oak RV Park in Villa Ridge operates year-round with full hookups including 30 and 50-amp service, making it suitable for larger rigs. Beyond the Trail RV Park features pull-through sites with full hookups and borders the Katy Trail for easy access to nearby towns. RV Self-Park in Sullivan offers big-rig friendly sites with water, electric, and sewer connections. "This is a small RV park just off I-44 about 20 minutes from Meramec Caverns. It's very close to the highway so there is lots of highway noise. Some sites are farther away so not so bad," noted one visitor about Birch Creek RV Park.

    Most RV campgrounds in the area maintain sanitary dump stations, though availability varies by season. Cell service is generally reliable throughout the region, with visitors reporting 2-4 bars on major carriers at most parks. Reservation policies differ between parks - Hermann City RV Park operates seasonally from April through November, while others like Pin Oak RV Park remain open year-round. Pet-friendly policies are standard across most facilities, with designated pet areas at some locations. Proximity to I-44 means road noise affects certain sites, particularly those closest to the highway. One traveler mentioned needing leveling blocks at some parks despite the advertised level sites. Propane service is available at select locations, and laundry facilities can be found at parks like Birch Creek. For RVers planning extended stays, several parks offer weekly and monthly rates with discounts for longer commitments.

      little lost creek

      Nice quite little place. Few hikers walk on the outskirts of you site, but nice about it! Noisey road! More traffic than you’d think! Open skies, beautiful place! They give you a map here also.

      Hummingbird Hollow Outdoors Farm Sanctuary

      It’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.

      Daniel Boone Conservation Area

      Pretty 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.

      Sundermeier RV Park

      My 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

      Hickory Ridge Campground

      Staying 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.

      Graham Cave State Park Campground

      Graham Cave

      Graham 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.

      Graham Cave State Park Campground

      Great overnight

      Hardly anyone here. On a Tuesday in October. Took a primitive site. Reasonable. Fairly quiet. Some ambient noise from i70

      Meramec State Park Campground

      It 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.

      Riverside Landing

      My 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!

    Guide to Union

    RV campgrounds near Union, Missouri provide access to both city attractions and natural areas along the Missouri River valley. Many parks are situated within a short drive of I-44, making them convenient stopover points for travelers heading between St. Louis and the Ozarks. The terrain in this region combines river bottomlands with rolling hills, creating diverse landscapes surrounding each campground.

    What to do

    Visit wineries and breweries: Beyond the Trail RV Park in Defiance sits adjacent to the Katy Trail with easy access to local wineries. "Brewery just on the other side of the campground with good beer and food. 5/5 if they every paved the campground," notes Matthew H. The park serves as a gateway to Missouri wine country.

    Explore historic towns: From Sundermeier RV Park, visitors can access historic river towns. "Easy ride in to St. Charles a wonderful historic river town on the Missouri River. Great shops, great restaurants," writes Cheryl K. The park connects directly to the Katy Trail for cycling into town.

    Water recreation: The 370-acre lake at St. Peters' 370 Lakeside Park offers multiple water activities. "The park/campground rents paddleboats, kayaks, and canoes in addition to different kinds of bikes. There is a walking trail around the lake (4+ miles)," reports Mats. Fishing is permitted in the lake with proper licensing.

    What campers like

    Direct trail access: The placement of Beyond the Trail RV Park gives campers immediate entry to the Katy Trail. "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," shares Sam C.

    Urban convenience with nature: RV Self-Park in Sullivan balances accessibility with comfort. "Very well lit, very clean and very easy to get in and very secure with a ton of cameras. Also has a really nice dog area," says Grant. The park offers quick highway access while maintaining security features.

    Late check-in options: Many Union area RV campgrounds accommodate travelers arriving after hours. "Easy to book online even the day of. Choose your spot ahead of time and pull in, easy as that! Had no problem booking around 7pm the day of and arrived around 1 am quietly set up in my previously reserved spot," explains Brooklyn G. about Beyond the Trail RV Park.

    What you should know

    Highway noise levels: Several campgrounds sit close to Interstate 44, creating varying noise conditions. One camper at RV Self-Park noted: "You will hear some highway noise, but honestly, after years in trucking, it just felt like home."

    Weather considerations: The region experiences seasonal flooding risks. At St. Peters' 370 Lakeside Park, staff provide weather updates: "A park ranger went around to every site and notified every camper of where the shelters were and gave out a flyer about the specific weather forecast!"

    Limited shade at newer parks: Many RV campgrounds in the Union area lack mature trees. "This will change over the subsequent years, however, as there are many relatively newly planted trees," explains Suzie S. about 370 Lakeside Park. Consider bringing portable shade structures during summer months.

    Tips for camping with families

    Playground access: Several parks offer dedicated play areas for children. "The grounds are clean and pleasant, if a bit sparse with little shade. There is boating and archery on site, a dog run, and a small playground," notes a camper at 370 Lakeside Park.

    Fishing opportunities: Pin Oak RV Park provides family-friendly fishing. "A nice private catch and release pond, an old little mini golf setup, a small (but adequate) swimming pool kept the kids busy," writes Carrie A. No fishing license required for the private pond.

    Halloween events: Seasonal activities attract families to certain campgrounds. "We go every October for Halloween. It is tight you need to reserve a premium spot for a little room. Staff and owners are great lots to do for the kids," shares Tim K. about Pin Oak RV Park's annual Halloween bash.

    Tips from RVers

    Site selection strategy: At Cahokia RV Parque, site placement affects experience quality. "The 50 amp spaces were the only ones with firepits. RVs are close to one another but I was completely okay with that," advises Kelsey R. Request spots farther from highways when possible.

    Utility connections: Check hookup locations before arrival. "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 Josh F. about Casino Queen RV Park.

    Water pressure variations: Water systems can run stronger than expected at some parks. Susan L. noted at 370 Lakeside Park: "The water pressure was so strong that I could barely open the water pump!" Consider using a pressure regulator at Union area RV campgrounds.
