Pin Oak RV Park maintains a pet-friendly environment with sites that accommodate tents, RVs, and cabins. Located in Villa Ridge, this year-round campground features picnic tables and fire rings at each site, with drinking water and electric hookups available. Most sites are close together with limited privacy, but the park's clean facilities and amenities make it popular for families with pets. Klondike Park in Augusta also welcomes pets with tent and RV sites, plus several primitive walk-in sites ideal for those seeking more seclusion. Some campsites offer hammock stands and are located near clean pit toilets, though the campground's proximity to a power plant results in a background hum that may be noticeable at night.
Meramec State Park Campground provides pet-friendly accommodations with boat-in, drive-in, and walk-in access options. The park maintains trails suitable for dog walking, with access to water for pets that enjoy swimming. Campers should note that while most sites welcome pets, the campgrounds can become crowded during peak seasons, especially on weekends and during Halloween events when Pin Oak hosts special activities. Robertsville State Park Campground offers additional pet-friendly options with access to water for dogs that enjoy swimming, though all pets must be leashed when outside designated areas. Nearby St. Charles County Klondike Park features tent camping and pet-friendly cabins, with direct access to the Katy Trail for hikers and cyclists with dogs.

This was our first trip together in our new camper. It was a little rough assessing the place thru the website but the reviews swayed us. There are walking paths all around and a beautiful lake /clubhouse area. Super people running the place and of course other campers were so helpful. We took our 2 dogs and would have loved a little more grass for their paws as the entire camping area is rough gravel. We’re hoping for a dog park in the future....? The lake has many easy entrances for swimmers near the club house - broad steps or large boulder for the more adventurous. Can be a bit slippery tho so bring your water shoes. Kids seemed to have little problem. Saturday night there was live music. Just a single guy with a guitar but great choice of music and great singing voice. Had a great 2 days. We plan to come back.
This campground is fairly close to downtown and very close to lots of shopping. A great place to stay to stock up on supplies before heading west. We stayed 2 nights to have a day to visit the Gateway Arch. The pool and playground seemed nice even though we didn’t use them. Nice dog park for smaller dogs. Several cabins are available along with RV sites. The tent sites are next to a river under large trees. Plenty of spaces for big rigs. Our site was no very level but nothing our auto-leveling couldn’t handle.
Large grassy camp sites, dog park and clean restrooms/shower house. Lake is very pretty and great staff.
Nice, clean campground, level pull-through sites - ours had a paver-patio and grill, a lot of shade throughout, dog park, and a creek to explore. This was our 2nd time here. Close to Saint Louis, Six Flags, and hiking.
We had a beautiful campsite with soft grassy ground. We did have a mole or something burrowing around so you had to watch for loose dirt clods but that was NBD. The site had a picnic table and fire ring. There were pit toilets, no showers. Spigots throughout the area. Within walking distance of the river and trail access. Beautiful hiking on the bluffs above the river. The hosts were really friendly. There was also a very cute and very friendly kitty running around the area hunting grasshoppers. He hung out for some pets and cuddles then wandered off for some more adventure. I kind of want to be that cat. ^_^
Easy off I-370, campground is new and large. It is on a lake with bike trails, kayak rental, and kids splash pad. Staff were helpful. I received about 5 pieces of paper when checking in. You need a code to get into the dog park. Shopping nearby. Used this as a base to visit historic St Charles.
This is a KOA, so you know what to expect. Pull through, level sites, lots of shade, dog park, pool, and a creek are all here. Have been here before, will be back!
We stayed one night in campsite 65. Onondaga Cave is amazing with the new lighting; it just reopened July 4, 2024. The river is still fantastic fun, especially for our grandkids ages 9 and 12.
Avoid campsite 65 when it rains. We had over an inch of standing water on the concrete pad when we arrived. 18 hours after it stopped raining, we still had some water on the concrete pad.
Other than the water, Onondaga Cave SP has been one of my favorite places to camp in Missouri for more than 20 years.

Explore cave systems: Meramec State Park Campground offers guided tours of Fisher Cave. "Pay the extra for the caves tour! Down the road there's an old iron foundry and a historic cemetery to explore," advises Lynn G., who found the campground "right on the edge of the river" with trail access directly from campsites.
Mountain biking trails: Greensfelder County Park features technical mountain bike sections within the park. "The park is known for its well-groomed trails, which are used by hikers, mountain bikers, and equestrians alike," notes Lucas M., adding that "plenty of stables surround the area, where you may rent a horse and go for a stroll through the woods."
Wine country access: Beyond the Trail RV Park serves as a gateway to local wineries. "This is just a great park. It is located in a sleepy little winery town. It is just a few minutes from the main part of town with multiple beautiful wineries within a few miles," reports Jamie C., who appreciated that "the park is bordered by the Katy Trail which will take you into town."
Riverside recreation: Meramec Caverns Natural Campground provides direct river access. "The area as a whole is neat. The primitive sites are spacious and lovely," notes Jamie C., who particularly enjoyed the water activities: "The river was amazing. We got down early to ensure we had a spot for our chairs and umbrella. Our kiddos played (with life vests) for 8 hours straight."
Trail connections: St. Charles County Klondike Park offers exceptional access to the Katy Trail. "I have bike-packed along the Katy and this is an excellent spot for an overnight(s) stay. It is a tough, but short, climb from the trail," explains Mike L., who recommends securing food supplies before arrival since "there are no services in the park."
Privacy options: Robertsville State Park Campground features secluded camping areas. "Not much to do here, it's just a place for me to camp 15 minutes from home. It has a nice loop trail behind the camp ground that goes down to the river," shares Tony S., who appreciates the park's quiet atmosphere.
Seasonal considerations: Pin Oak RV Park experiences crowding during Halloween events. "We go every October for Halloween. It is tight you need to reserve a premium spot for a little room," advises Tim K., who notes many campers "rest the space for the year" as weekend getaways.
Connectivity limitations: Cell service varies dramatically between campgrounds. At Meramec State Park, "There is WiFi available but it is not reliable. The cell phone service is virtually non-existent," reports Mats, who had to "cut our visit short" after planning to work remotely.
Noise factors: Some campgrounds experience noise from nearby infrastructure. At Klondike Park, Dave B. notes "the only issues is the loud hummmmm of the power plant can be heard in the night," despite finding it an "amazing park close to the city" with "great lake and hiking trails."
Water recreation options: Meramec Caverns Natural Campground offers swimming areas for children. Heather G. appreciated how staff "put us on an end spot farther from the high traffic high noise area" to accommodate her husband's PTSD, noting they "were close to the beach, but further from the noise."
Planned activities: Yogi Bear's Jellystone Park Resort provides structured entertainment for children. "This is a nice private campground as there are many amenities such as a pool, putt putt golf, volleyball, and more. They also host daily kids activities and crafts," writes Lindsey R., calling it "a very family friendly campground."
Wildlife viewing: Meramec State Park features abundant wildlife. "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.
Site selection strategy: Beyond the Trail RV Park offers varying site quality. "Stay away from creek side spot lots of mosquitoes and possible flooding with enough rain," advises Matthew H., who appreciated the "great location to go to all the wineries and restaurants nearby" with a "brewery just on the other side of the campground."
Level pads: Greensfelder County Park provides concrete pads at specific sites. "Most sites are flat and paved," notes Matthew H., who adds important electrical details: "Only sites 20-29 have electric and 28 can't be reserved," with "2-20 amp plugs and 1-30amp plug" at most sites.
Hookup specifics: Pin Oak RV Park offers full-service sites with specific limitations. "The sites are gravel and close together do not much privacy. They come with water, sewer & electric," explains Joel R., who notes the park has internet, "but it is weak and spotty."
