This was a nice KOA campground for our single overnight. Many activities available right at the campground - plus a nice pool and good size sites with plenty of shade. Eureka is a nice town with everything you’ll need as far as food and supplies. Six Flags close by, but travel time to St. Louis was a little more than we anticipated (this wouldn’t be my first choice if the Arch and riverfront are primary destinations).
There is lots to do at this park. There is a pool, bike rentals, dog park, movie night, basketball court, and more. You can bring your RV, travel trailer, tent camp, or stay in a cabin. Most of the sites are in the shade and are fairly level. The bathrooms were clean and well maintained. They have Ele/water and Ele/water/sewer sites. It is close to train tracks, but I only heard the train once at night. It’s close to Six Flags, shopping, and restaurants. They even have a cute caboose cabin you can stay in.
Lots to do at this campground and lots to go see. Close to all the St Louis attractions as well as practically across the street from Six Flags. There is a pool and store on site. Just a couple miles away there is a grocery store and restaurants galore.
There are two two very good RV dealerships nearby with all the supplies or service you could need.
There is a group pavilion and meeting room available. I was there with a large group from Sisters on the Fly and we were comfortable. There were at least fifty of us and we we not the majority camping there.
All the facilities were clean and well maintained.
