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."
