    Meramec State Park Campground's pet-friendly sites accommodate tent campers, RV travelers, and those seeking cabin lodging near Sullivan. Pin Oak RV Park offers full hookups and welcomes pets throughout its spacious grounds in Villa Ridge. Sites at the back of the property are larger while middle sites appear more crowded. Both campgrounds maintain clean facilities with showers and flush toilets. Pin Oak's lake provides fishing opportunities for campers with pets, though leashed dogs must be supervised at all times. The sites are gravel and close together with minimal privacy, and most campgrounds in the area maintain standard pet policies requiring dogs to be leashed, cleaned up after, and not left unattended.

    Robertsville State Park Campground features 28 heavily shaded sites that accommodate pets within easy access to the Meramec River. The park provides two hiking trails suitable for dog walking, with the loop trail behind the campground leading down to the water. The park remains quiet and secluded with minimal facilities but offers clean shower houses and bathrooms that are regularly maintained. Meramec Caverns Natural Campground allows pets at both tent and RV sites as well as their cabin accommodations. During summer months, special attention should be given to pets as temperatures can rise quickly in dog-friendly campsites with limited shade. Most campgrounds in the region require vaccination records and limit pets to two per site, with additional fees sometimes applied for cabin stays.

      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

    Camping areas near Union, Missouri provide access to the Meramec River watershed at elevations between 500-800 feet with moderate humidity during summer months. Most campgrounds in this region experience temperatures averaging 85-95°F between June and August, with rainfall concentrated primarily in spring. The terrain features limestone formations, deciduous forests, and river access points within a 30-minute drive of Interstate 44.

    What to Do

    Fishing opportunities: At Meramec Caverns Natural Campground, visitors can fish along the river shoreline. "The campgrounds are clean and beautiful, and even during peak times the people that stay are usually very friendly, as are the rangers when they make their nightly rounds," notes Randy H.

    Cave exploration: Fisher Cave tours near Sullivan offer underground adventures for families. "Pay the extra for the caves tour! Down the road there's an old iron foundry and a historic cemetery to explore," recommends Lynn G. from Meramec State Park.

    Trail hiking: The loop trail system at Robertsville State Park provides forest and river views on moderate terrain. "I do wish they had a playground or some level place for the kids to play, but overall it was very nice and quiet," mentions Montt B., highlighting the natural focus of the park.

    Mountain biking: Technical bike sections at Klondike Park provide challenges for riders of all skill levels. "There are several technical mountain bike sections that are located in the park. Bring your mountain bike and have a go!" explains Megan K., noting its dual appeal for Katy Trail bikepackers.

    What Campers Like

    Shower facilities: Modern restrooms with hot water are available at Beyond the Trail RV Park. "Clean restrooms and shower house," notes David E., though he mentions the "WIFI wasn't great when we stayed here twice last year."

    Campsite privacy: Sites at the back of Pin Oak RV Park offer more seclusion. "Sites at the back of the property are large. Sites in the middle seemed more crowded," explains Chad H., providing insight on optimal site selection.

    River proximity: Klondike Park sites provide easy access to water. "The campground is located in a gym of a park located along the Missouri River. Reservations are required and the sites are in high demand," states Marty C., emphasizing the need to book early.

    Shade coverage: Most Meramec area campgrounds offer tree canopy for summer heat relief. "The State Park has a great canopy of trees located next to a stream as a setting for the campground that bounds with wildlife. We saw deer and raccoons here that entered our campsite," shares Tom K.

    What You Should Know

    Cell service limitations: Some campgrounds have connectivity challenges. "The cell phone service is virtually non-existent. We had planned to work from here and had to cut our visit short," warns Mats about Meramec State Park.

    Drainage concerns: Yogi Bear's Jellystone Park Resort and other low-lying campgrounds can experience flooding. "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," reports Adam F. about Beyond the Trail RV Park.

    Highway noise: Proximity to I-44 affects sound levels at some campgrounds. "There is quite a bit of traffic noise from I-44 and there are a lot of excess lights kept on all night long," notes Joel R. about Pin Oak Creek.

    Seasonal closures: Some facilities operate with limited schedules. "Winter stop for me so I have only seen the shower house from the outside but I would expect it to also be well maintained," shares Teresa T. about Robertsville State Park.

    Tips for Camping with Families

    Pet exercise areas: Several dog friendly campgrounds near Union provide designated spaces for pet play. "The park provides two hiking trails suitable for dog walking, with the loop trail behind the campground leading down to the water," notes Tony S. about Robertsville State Park.

    Kid-friendly activities: Stanton-Meramec KOA offers structured programming for children. "We go every October for Halloween... lots to do for the kids. Lot of campers there that are weekend getaways for people rest the space for the year," shares Tim K.

    Swimming options: Several campgrounds maintain pools or river beach areas. "Nice pool area. They have canoes for rental onsite. Nice place but sites are un-level for Motorhomes and they are a little tight," reports Schelly D. about Stanton-Meramec KOA.

    Wildlife viewing: Bring binoculars for deer, raccoon, and bird watching opportunities. "We saw deer and raccoons here that entered our campsite," shares Tom K. about his experience camping in the area.

    Tips from RVers

    Hookup configuration: Water and sewer connections at some sites require extra hose length. "The site services, electric, water and sewer, are located to the front of the site and extensions were needed for both the electric and sewer," advises Craig H. about Beyond the Trail RV Park.

    Site leveling: Many campgrounds have uneven pads requiring blocks. "The sites are level, and there is plenty of shade. (One advantage of being an older park.) But everything is just a little run down," observes Joel R. about Birch Creek RV Park.

    Space considerations: RV sites vary significantly in size across the region. "Fairly steep grade, especially right out our camper door was a big drop off. Our water hook up and electric hookup was significantly far apart," notes GW C. about Jellystone Park, highlighting the importance of proper site selection.

    Weekend crowding: Dog friendly campgrounds near Union become busy Friday through Sunday. "Saturday night they had a band making noise for 3 hours!" reports Joel R. about weekend activities that may impact your camping experience.
