"We lucked out and were able to reserve one of the last spots (site #76) which happened to have a nice view of the lake and several short trails down to the water.

Walking trails and biking: The 4-mile paved trail around the lake at St. Peters' 370 Lakeside Park provides recreational opportunities beyond camping.

What campers like

Value for budget campers: Horseshoe Lake State Park Campground provides affordable camping options close to the St. Louis area.

On-site food options: Cahokia RV Parque features an on-site restaurant that receives high praise from visitors. "The only real complaint was that it was a bit of a wind tunnel. I don't know if that is because of were it sits between the river/lake and a levee for the river or because it was spring time and windy anyway," shares a camper who otherwise enjoyed their stay. Another adds, "Do NOT miss the BBQ place in the parking lot... fantastic food and a 10% discount for park customers."

What you should know

Seasonality and flood concerns: Several campgrounds in the area experience seasonal closures or flooding issues. One camper at St. Peters' 370 Lakeside Park points out that "One of the downsides to this location is that it is prone to flooding. It was out of commission for most of the summer of 2019 as the entire area was flooded."

Train noise: Various campsites near the St. Louis metro area experience train disturbances. At Granite City KOA, "We stayed in a tent spot... Had shade and a nice concrete pad to park on. Good clean power. Clean bathrooms and pool looked like it was taken care of... It's not in the prettiest location, very industrial and the train tracks run close. First night one came through blowing its horns around 5am."

Limited shade at newer sites: Some campgrounds lack mature trees for shade. A camper notes about St. Peters' 370 Lakeside Park: "The grounds are clean and pleasant, if a bit sparse with little shade. This will change over subsequent years, however, as there are many relatively newly planted trees."

Tips for camping with families

Playground access: Dam West Spillway offers family-friendly features with play areas for children. "Big, spacious campsites with really pretty, big trees for lots of shade. The bathroom and shower facilities are FABULOUS, and super clean. Rangers are walking/driving around, and really friendly. Marina and beach are close," shares one family that enjoyed the amenities.

Weather preparedness: Summer temperatures frequently exceed 90°F in this region, requiring appropriate planning for comfort. According to one camper: "We stayed the weekend here and it got really busy. When we tried to book online, all were taken but saw they had a few sites that were first come. Luckily, we got one of the last two."

Reservations for peak seasons: Pet-friendly campgrounds near O'Fallon fill quickly during summer weekends and holidays. At Eldon Hazlet State Park, "The campground filled up by 11am on Friday, which was a surprise to us," warns a camper who almost missed getting a spot.

Tips from RVers

Utility locations at sites: Draft Kings at Casino Queen RV Park has an unusual setup for hookups that requires planning. "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," notes one RV owner about this practical consideration.

Military base access for veterans: Scott AFB FamCamp offers specialized options for service members with proper credentials. "Does not have sewer hook up. One dump station that is clean, black water hose provided, but used a lot. Expect to wait your turn. A lot of spots are not level, so come prepared," shares a military camper regarding the practical amenities.

Water quality variations: When staying at pet-friendly campsites near O'Fallon, water quality can vary seasonally. As one camper at Eldon Hazlet noted: "Only complaint that I have was the potable water supply. I filled by trailer's tank at the drinking water supply when you enter the campground. It was extremely dirty with a lot of copper colored solids."
