What you should know
Urban vs. rural experience: Campgrounds closer to St. Louis sacrifice solitude for convenience. At Cahokia RV Parque, a camper observed: "This is not a rural campground. It's a centrally located campground in the Metro St. Louis area. It's close to interstates and it's a short drive across the river to Missouri attractions."
Seasonal closures: Winter camping options are limited, with some facilities closed seasonally. A reviewer at Dr. Edmund A. Babler Memorial State Park noted: "The bathhouse with flush toilets closes November 1 and doesn't open until the spring. During the winter the only water spigot is available located near the camp hosts."
Noise considerations: Train noise affects several campgrounds near Waterloo. At St. Louis West KOA, a camper mentioned: "Close to train tracks and highway, but didn't notice with AC on in the camper." Another reviewer more directly stated: "It will be even better when they invent silent trains."
Tips for camping with families
Look for dedicated amenities: Some campgrounds offer better facilities for children. At St. Francois State Park Campground, "There is a playground, pool and pond area to walk around." The park is "very family friendly" according to multiple reviewers.
Consider site spacing: Some campgrounds have tight sites that may not work well for families. At Dr. Edmund A. Babler Memorial State Park, a camper observed: "I am not a fan of how small and close together these sites are and during the season they fill up quickly." Look for campgrounds with "spacious sites" instead.
Wildlife education opportunities: At Horseshoe Lake State Park, wildlife viewing becomes an activity itself. "Good fishing, trails and memories waiting to be made," notes one visitor. The park surrounds a natural lake habitat with various wildlife viewing opportunities.
Tips from RVers
Check site hookup placement: At Casino Queen RV Park, a camper warned: "Utilities are set up weird on all sites - Water and electric are at the very rear of the site by the sewer, so you will need a decent sized hose to reach if your water intake is in the front of your camper."
Site leveling needs: Some campgrounds require extra preparation. At Covered Bridge RV Park & Storage, a visitor noted: "A lot of spots are not level, so come prepared." However, the park does offer "concrete pads, easy hook-ups, good internet, and paved streets."
Gate access procedures: Several campgrounds near Waterloo require security codes. At Casino Queen RV Park, "You need a code to get in the gate, so you must register in advance. It takes you to gates that have been closed for years. So put in Commissary to get on base. Once on base put in FamCamp."
