Best RV Parks & Resorts near Union, MO

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.

    Nice spot for quick stop

    30 & 50-Amp Electrical, Water & Sewer Hook-ups. Concrete pads. Bathroom/showers are clean. Pet friendly, coin laundry. Some pull thru sites. Adjacent to the Great American Flea Market on weekends if you like that stuff.

    Lazy Day Campground

    One of the Nicer Private Campgrounds

    The campground (CG) was easy to find, located just 5 miles off I-70 with clear signage along the way. We parked at the designated registration area, and check-in was quick for our one-night stay. We were then escorted to pull-through site 17 with full hookups. The gravel pad was fairly level, and although the utilities were toward the back of the site, we had no trouble connecting. There were two sewer hookups—a nice touch. Water is shared, but the pressure was solid at about 50 psi. Sites are decently spaced, though some are closer together; ours was relatively close to the next site on the driver side. Our site had a nice yard, picnic table, and fire pit, but if someone had been in the site next to us, we would have been sharing that area. We got 2 bars on Verizon and 3 bars on T-Mobile, and our T-Mobile Home Internet worked very well. The CG WiFi was fine for email and web browsing. While the grounds have mature trees, most sites—including 17—are satellite-friendly. The 1/2-acre dog park was especially impressive. There was a mix of permanent, seasonal, and short-term guests. The park was clean, well-maintained, and featured fun wood carvings. The setting includes a pond and a trail to a small lake. A small camp store, ice, and propane are also available. Overall, this is a solid CG for overnight or extended stays. Out of the 325+ campgrounds we've visited, this one has the best rules sheet—hands down. It's hilarious, and you’ll instantly get their vibe!

    Hermann City RV Park

    Birthplace of Missouri Wine Country

    Hermann is an amazing village of old world charm nestled into the Missouri River Valley. Picture book clock towers and church steeples among 19th century era brick cottages adorn the historic German immigrant influenced village with plenty of restaurants, shops and galleries for wandering pleasure. Hermann is right in the heart of Missouri wine country with two stunning wineries within walking distance of the campground; Stone Hill and Hermannhof...these are not to be missed. For cycling enthusiasts...the 240 mile Katy State Park Trail(nation's longest Rails to Trails Project) is just across the river from Hermann and follows the Missouri river through countless little river towns rich in history. A short distance south on highway 19 is the Swiss Meat Company, well worth a visit. The city park has an amazing campground operated by the City of Hermann. They offer full hook up sites(water, electric and sewer), water and electric, electric only, and tent camping. 18 full hook up sites are paved with grass areas and fire rings, 25 full hook up sites are on a paved parking lot(big rig friendly), and 8 electric only sites are on grassy area. A bath house with showers and restrooms are available, along with a dump station.To make a reservation please call the City Office, 573-486-5400, Monday-Friday between 8:00 a.m.-5:00 p.m. Full hookup(water, electric& sewer)…..$30.00 Water and electric…..$25.00 Electric only…..$20.00 Tent camping…..$15.00 This is a great spot for an overnight...but don't cut yourself short...it's absolutely great for an extended stay. http://hermannmo.com/campground/

    Meramec State Park Campground

    Mera-culously huge

    Huge park with tons of amenities and options. Although there is year round Camping, the host on site advised water to each individual site will be turned off end of October for winter. Potable water is available near dump stations (hmmm....). Very well kept, and vacant this time of year, affords the opportunity for a more private camping and river experience. Clean well kept shower houses. Lodge & cabin rentals also available. Boat ramp in back of campground. Campsites with blue bands and parking stops are ADA compliant with concrete pads, elevated grills plus fire ring and picnic table.

    St. Peters' 370 Lakeside Park

    RV delight

    I wanted to escape the house and go camping while on the work from home order (Covid-19 happening at the time of this review), so I headed to a very local park and campground to pitch my tent. I've been to 370 Lakeside Park many times to walk around the huge lake and to hear concerts in the summer, but I had never camped there. Still haven't. I'll explain. Due to the Covid-19 pandemic, they were not so keen on having tent campers. But they were very nice and gave me the general lowdown on this "in the city" campground. Since they opened the campground, most of their campers have been RV owners, and so it is really designed for the RV camper. There is a small primitive section for group tent camping, but the majority of the sites are full hookups for RVs. Some sites are pull through and some are back in. All have picnic tables and fire pits. The park has planted some trees, but they are really just saplings, so there is no shade yet. There is a nice bathhouse with free showers for the campers and pay laundry. If you are lucky, you can get a site close to the water, but it means the walking trail is right next to your unit. Trade offs, I suppose. One couple I talked to was camping long term (I think they are permanent RV'ers) and they got a free membership to the St Peter's RecPlex recreation center with their long term spot (they said something about having to book a least a month out to get this perk). One of the downsides to this location is that it is prone to flooding. It was out of commission for most of the summer of 2019 as the entire area was flooded. But 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. The lake is great to walk around, about a 3 mile walk or bike on a paved trail. You can see all kinds of wildlife in and around the lake- deer, bald eagles, pelicans, ducks, snakes. In the summers they have live music in the large pavilion, and you can rent kayaks and other small boats to take out on the lake as well as bikes to ride around on. The office told me that they have 24 hour on site security also. If I really wanted to tent camp, I could rent a section of the group camping area, but $30 seemed pricey for just me, and it was very soggy to boot. Or I  could rent an RV spot, but $45 was silly when I don' t need hookups.

    Onondaga Cave State Park Campground

    Clean and quiet park

    We stayed one night on our way through Missouri. It’s only about ten minutes south of I-44. The campground was only about half full, so it was nice and quiet. All sites have a concrete pad for the RV and for the picnic table. Includes water and electric. Playground, laundry room, and dump station. Hiking trails available from the campground and cave tours on weekends. We stayed at site #65 which is close to the entrance/restrooms and has no campsite on either side.
