    The rolling hills surrounding Union, Missouri feature a mix of state parks, private campgrounds, and riverside camping areas within a 30-mile radius. Meramec State Park Campground, located about 15 miles southwest of Union, provides year-round camping with full hookup sites, tent areas, and cabins along the Meramec River. Nearby, Meramec Caverns Natural Campground offers 200 sites with similar amenities plus access to the famous cave system. Robertsville State Park Campground, situated northeast of Union, provides boat-in and drive-in camping options with electric hookups and shower facilities. The region balances developed campgrounds with more rustic options, creating opportunities for both RV travelers and tent campers.

    Reservations are essential at most established campgrounds, particularly during summer weekends and fall color season. Many state park campgrounds feature concrete pads for RVs and level tent sites, though drainage can be an issue during heavy rains. As one camper noted about Onondaga Cave State Park, "Avoid campsite 65 when it rains. We had over an inch of standing water on the concrete pad when we arrived." Most campgrounds in the area maintain well-kept shower facilities and bathrooms, with varying levels of hookups available. Cell service is generally reliable throughout the region, though coverage may be spotty in some river valleys. Winter camping is available at several locations, though water systems may be winterized during freezing temperatures.

    State park campgrounds receive consistently high ratings for their natural settings and recreational opportunities. Campers frequently mention the excellent hiking trails, cave tours, and river access as highlights of their stays. The Katy Trail, a 240-mile rails-to-trails project, connects several camping areas and provides cycling opportunities. According to one visitor at Beyond the Trail RV Park, "The Katy trail borders the park for easy access to town. Beautiful views across a large farm field to the hills beyond with incredible sunsets." Visitors also appreciate the proximity to Missouri wine country, with several campgrounds serving as convenient bases for exploring local wineries. Noise levels vary significantly between rural state parks and campgrounds closer to highways or urban areas, with some RV parks near St. Louis experiencing noise from nearby transportation corridors.

      Graham Cave State Park Campground

      Good over night stay

      We can rough it. This is a wooded campground with fire pits and worn out wooden picnic tables. I saw outhouses but didn’t look inside. It has electricity and water pumps where you can get water. In the heat all I care about is electricity for air conditioning. It is an old campground in need of TLC. But at $21 for seniors, I can’t complain. We are just passing through

      Meramec Caverns Natural Campground

      Adequate camp site

      This is definitely more of a “camp” site with bugs and pretty basic needs. When we arrived on Thursday no one was there. Easy to park. When we left Saturday morning of Labor Day, it was a parking lot zoo! Location near caverns is super cool. Bathrooms are sketchy. Super buggy and only a screen door between outside and toilets/showers. It’s a little concerning for a women to shower behind a curtain and only a flimsy screen door to outside. We were backed to river in a 35’ travel trailer no sewer at site and dump station on way out was in passenger side while all dump pipes are on driver side. It worked to go under but interesting to solve.

      Pin Oak RV Park

      Mostly long term campers

      Most of the campers here live here long term. It’s more of a trailer park than a camping spot. They have a pool but most people probably wouldn’t use it. The restrooms and showers or shower, only one for the entire grounds, are 2 stars. If you needed an emergency stop over it would work.

      Hickory Ridge Campground

      Perfect for my needs

      Late arrival. Yet Host was accommodating. Needed a campsite for Roof top tent site. Dog Blue and myself. They have a large pool and off leash dog park. Showers included in camping fee. I enjoyed my stay. Very quite.

      Quiet and very clean

      This campground is very well taken care of. The kids had plenty of things to do to stay busy and entertained outside.

      Cuivre River State Park Campground

      Nice place for an overnight

      Secluded state park but a little hard to get to when pulling a 34 foot fifth wheel. Lots of ups and downs on the road. Love the fact that you are absolutely in the hills of Troy MO with nothing else around you. We stayed during the week the end of August and there were hardly anyone else here. Very quiet. No road noise whatsoever. You felt very much in the woods.

      Courtois Creek Dispersed

      Beautiful spots on river

      There are a few loops to park in, and a couple of spots are right on the river. I drove back in my truck scouting for future spots to bring my trailer. This is not a spot I'll bring my camper.

      The road is very narrow and there are washed out spots, and one area that is just large rocks. It was too rough for my camper. My Tacoma was fine, though. If you're driving a high clearance vehicle, you'll be okay. Bugs were bad, as expected for August.

    Guide to Union

    Winter camping is available throughout the Union, Missouri area, though several campgrounds reduce services during freezing temperatures. The region's terrain features limestone bluffs, oak-hickory forests, and elevations ranging from 450-900 feet above sea level. Proximity to both the Meramec and Missouri Rivers creates diverse camping environments with variable drainage conditions depending on seasonal rainfall patterns.

    What to do

    Explore underground cave systems: Fisher Cave at Meramec State Park Campground offers guided tours through impressive formations. According to one camper, "Highly recommend taking a cave tour of Fisher Cave! So neat!" The tours provide educational content about local geology and history.

    Bike the Katy Trail: This converted rail trail passes through Augusta near Klondike Park, offering level riding surfaces suitable for all abilities. A visitor noted, "Klondike park is a gorgeous park along the Katy Trail in Augusta, MO. The campsites are very quiet, very family friendly park."

    Fish the stocked ponds: Multiple campgrounds maintain fishing ponds with catchable species. At Pin Oak RV Park, "Fishing pond was a blast for the kids!" Another camper mentioned, "There is a pond with some decent sized fish in it."

    Seasonal weekend activities: Many campgrounds schedule structured events throughout camping season. One visitor to Jellystone Park noted, "We go every October for Halloween... Staff and owners are great lots to do for the kids."

    What campers like

    Woodland camping sites: Tree cover provides shade during summer months when temperatures frequently exceed 90°F. A camper at Robertsville State Park Campground reported, "I am loving my stay here at robertsville. The area is immaculately clean... It's in the tall trees with lots of shade and greenery you kind of feel like you're in a jungle."

    Well-maintained shower facilities: Multiple campgrounds receive positive reviews for clean bathroom facilities. "The bathroom and showers were clean, but dated. Not all facilities were in working order," according to one candid review of Pin Oak RV Park.

    Quiet weekday stays: Lower occupancy during weekdays creates more peaceful camping experiences. One visitor to Robertsville State Park noted, "If you go during the week you can have the place pretty much to yourself. And the racoons. Just saying."

    River access points: Proximity to waterways allows for swimming, wading and floating activities. A camper at Meramec Caverns Natural Campground shared, "Our kiddos played (with life vests) for 8 hours straight. The river can be dangerous there but if you respect it and have life vests, it makes for an amazing day."

    What you should know

    Varying site levelness: Many campgrounds have sloped or uneven tent sites. At St. Louis West / Historic Route 66 KOA, one visitor noted, "Decent tent sites, standard ones are definitely more private than those with electric and water." Another camper observed, "The site we had was very small and there are train tracks that run near by the campground so it can be quite noisy."

    Wildlife encounters: Raccoons are commonly reported at multiple campgrounds. "They dont give a darn who you are. They will walk right up to, smile, and take your chips. Scandalous!" according to one camper's experience at Babler Memorial State Park.

    Cell service variability: Coverage strength differs significantly between locations. A Meramec State Park visitor reported, "The cell phone service is virtually non-existent. We had planned to work from here and had to cut our visit short."

    Seasonal closures: Several campgrounds reduce amenities during winter months. At Babler Memorial State Park, "Not having water available except at the camp host, and no open restrooms and showers until after April 1, regardless of when the last freeze is was inconvenient for a spring break trip."

    Tips for camping with families

    Reserve premium sites when available: Larger campsites provide more space for families with multiple tents or equipment. A camper at Pin Oak noted, "Lot of campers there that are weekend getaways for people rest the space for the year," indicating how quickly preferred spots are taken.

    Consider cabin options: Several campgrounds offer cabin rentals as alternatives to tent camping. Klondike Park features "cabins [that] look great from the outside and sit back in the woods," providing more comfort for families with young children.

    Check activity schedules: Many campgrounds schedule weekend programming specifically for children. A visitor to Yogi Bear's Jellystone Park Resort shared, "They also host daily kids activities and crafts. A very family friendly campground and would highly recommend if camping with kids!"

    Look for playgrounds and recreational facilities: Campgrounds with dedicated play areas keep children entertained. "There is a pool, bike rentals, dog park, movie night, basketball court, and more," reported one family staying at Jellystone Park.

    Tips from RVers

    Request site specifications before booking: Campground layouts vary significantly in the Union area. A visitor to Pin Oak RV Park cautioned, "The sites are level, and there is plenty of shade. But everything is just a little run down... small campsites, very close to neighbors."

    Consider electrical capacity needs: Different campgrounds offer varying hook-up options. One RVer at Meramec State Park noted, "Most of the sites are flat and paved. The campground is right next to the Meramec River. There is WiFi available but it is not reliable."

    Check dump station conditions: Not all campgrounds maintain well-functioning dump stations. According to one camper at Robertsville State Park, "The dump station was a little broke down and the camp hosts had two big dogs that never stopped barking."

    Plan for highway noise at certain campgrounds: Road noise affects sleep quality at locations near major highways. A reviewer at Historic Route 66 KOA reported, "Close to train tracks and highway, but didn't notice with AC on in the camper."
