      St Louis Mulberry RV Gardens

      Could be worse

      Pulled in after the office had closed. They knew we would show up late. Around 1930. Still light outside. Opened the after hours check in and there was nothing for us. Or a map. Luckily there was a number to call. We called. Lady said she was on break and would call us back. Never did. After digging through emails, we finally found what site they had assigned to us. Very small print. Due to this app we were able to use the map posted. However there was no p10 site. Just up to p09. Called the lady back. Said there’s a p10 but that she would move us to p9 in the system. Just decide to stay because we’ve been driving all day. Beautiful grounds/location. Enjoyed a nice sunset. It’s sad it’s “kept up” by these people who can’t help someone because they are on break. Appears a lot of the campers live here. Which to me doesn’t matter. But it does when you can’t help someone for 5 min. Campers are nice. Bath house is a bit dirty. But usable. Skipping a shower tonight but the toilets and sink work.

      Draft Kings at Casino Queen RV Park

      Good location

      We only booked 1 night. Location was great but we had to make lot spaces a few times due to the uneven conditions of the lot spaces. Fortunately there was a nice gentleman who worked here and found a space that suited us better. The sites to the back are much better than the ones to the front! The view of the Arch is amazing but a little sketchy … especially at night! But it worked for the night!

      Sundermeier RV Park

      This RV park could be great but they have a bad wiring problem with some 30A receptacles and the office staff is extremely rude.

      I've stayed here a couple times and generally like the park. I appreciate owners investing in urban RV parks and I don't expect much for amenities in these kinds of settings. The staff were pleasant on a pre-arrival phone call and at check-in—but once there was an issue, the office staff member became very argumentative and rude, consistent with other online reviews.

      ELECTRICAL SAFETY WARNING DO NOT use the 30A receptacles here unless you have a surge protector with an Electrical Management System (EMS) that explicitly confirms correct wiring before connecting your RV. My equipment detected a Line/Neutral Reversal on some 30A receptacles; the 50A receptacles appeared to be wired correctly.

      When I reported this life-safety hazard, the staffer’s response was, “Don’t use your surge protector—they’re not compatible with our system.” As a licensed Electrical Engineer with 30+ years of experience, I can state that this is 100% nonsense. The surge protector was correctly doing its job by flagging a major wiring fault. Do not follow the staff's advice when they tell you not to use your surge protector to "make it work." That is irresponsible advice that is literally endangering your safety.

      The staff also insisted that they don't have a problem because previous 30A users without surge protectors had “no problems.” This is plausible because a Line/Neutral reversal doesn’t usually affect RV operation but the statement shows their complete lack of understanding of the actual problem.

      A Line/Neutral reversal energizes the neutral side of the RV's electrical system. This means the RV chassis, appliance housings, and internal neutrals, which should be near ground potential, all become live, creating a serious shock or electrocution hazard if someone touches those RV components while grounded.

      The sites are basic with level concrete pads in good condition and other utilities (water/sewer) were fine. Excellent location near the historic St. Charles district. WiFi is unusable—bring your own Internet source. Restrooms and showers are dated and not in great condition. There was also no hand soap at the bathroom sinks all weekend.

      This park should be a 7/10 rating, but the electrical hazard drops it to a 5/10. The staff bring the rating down further to a 3/10.

      Resort quality campground

      Very nice park. This is a big busy campground they have plenty of staff to handle the rush. Level concrete sites with FHU will definitely stay here again

      Fort Kaskaskia State Park Campground

      Awesome campground!

      The views over the Mississippi River are calandar-worthy! Very scenic from up atop the bluffs. A very old and historic cemetery is next to the campground. There is electric hookups 30 and 50 amp. No water/sewer but does have a dump station. Vault toilets.

      World Shooting and Recreational Complex

      Lot's of full hookups

      This was our first camp in our new to us travel trailer. Not many trees.  Site has tons of camping sites so finding a spot should not be an issue.  This is the site of the American Trap Shooters Association "Grand" Event.  During that event the first couple weeks in August the campground is full.  We were here last weekend in August. Only one other camper within sight of our spot Friday night and they were gone Saturday morning.  There is a shower house I believe but could not access a couple of the doors I tried.  I imagine they had some unlocked but I didn't try all the doors when I was there.

      Great experience

      This is a great campground and the owners are awesome! My husband and I are riding our bicycles cross country. The day we checked into the campground,he had a Crohn's flare/bowel block and went to the hospital for 4 days. The owners stored our bikes, watched our tent, and even picked us up from the hospital! Such nice people! The campground is clean, has a great showerhouse, lots of trees, and even has recliners in the laundry room. I highly recommend staying here!


    Guide to Trenton

    Camping spots near Trenton, Illinois center around Carlyle Lake, where average water levels vary by 5-10 feet seasonally due to flood control management. The recreation areas surrounding the lake feature extensive trail systems connecting multiple campgrounds, with most trails paved for multi-use activities. Most campgrounds maintain operating seasons from April through October, with some areas prone to closure during high water periods.

    What to Do

    Biking on paved trails: Boulder Recreation Area connects to an extensive trail system along Carlyle Lake. "Only stayed here once. Nothing bad but like others nearby even better," shares one visitor who appreciated the well-maintained paths around the Boulder Rec. Area.

    Wildlife viewing: Early morning and evening hours provide prime opportunities for spotting deer and waterfowl. "Oh and lots of deer bed down in the grassy areas at night, which was a fun thing to see!" notes a camper at Eldon Hazlet State Recreation Area.

    Fishing from shore: The spillway area offers accessible fishing spots without needing a boat. "Pretty nice area, there were alot of people when we were there. But alot of good trails and fishing at the spillway," mentions a visitor to Dam West Spillway.

    Swimming at dedicated beaches: Several campgrounds offer beach access within walking distance. "Had a lake front site with beachfront access. It was flat ground, everyone was so nice and it was so clean and the area was lovely," reports a Dam West camper.

    What Campers Like

    Spacious campsites: Many campers appreciate the generous site sizing throughout the area. "Campsites are large with plenty of room for camper and vehicles," notes a visitor to Boulder Recreation Area.

    Clean facilities: The shower houses and restrooms receive consistent praise for cleanliness. "The bathrooms and shower facilities are FABULOUS, and super clean. They smell like the laundry facilities as well, so great all around there," writes a Dam West Spillway visitor.

    Water views: Lakefront sites are highly sought after but available with advance planning. "Our site was on the shore and had good spacing from others. The bathrooms, showers, and laundry all close by. Good hot water in the showers," reports a Boulder Recreation Area camper.

    Affordable pricing: Corps of Engineers campgrounds offer discounts for federal pass holders. "Only negatives is that this campground is not open year-round," notes a visitor to Dam West Campground, where prices remain reasonable compared to private alternatives.

    What You Should Know

    Seasonal flooding affects access: Some campgrounds close temporarily during high water periods. "This park offers playground areas and more. Cabins, campsites with power or no power the choice is yours. However there are times this park cannot be accessed because of flooding," explains a camper at Eldon Hazlet State Recreation Area.

    Reservations essential for weekends: Popular sites book up quickly, especially during summer. "We arrived at this campground at 11am on a Friday only to find that that the first-come, first-serve sites were already full," reports a Dam West visitor.

    Water quality concerns: Some visitors report issues with water supplies early in the season. "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," shares an Eldon Hazlet camper.

    Varying bathroom standards: Facilities range from modern air-conditioned buildings to basic pit toilets. "The pit toilets that were spread across the campground were in horrendous condition and had wasps, spiders, and other critters hanging out," warns a visitor to Coles Creek Recreation Area.

    Tips for Camping with Families

    Playground options: Multiple recreation areas feature playground equipment for different age groups. "There are three playground areas, a basketball court, sand volleyball and a pool during summer months. Lots of families with kids, bike rides and plenty of other lake and outdoor activities in the area," notes a visitor to Eldon Hazlet State Park.

    Halloween events: Eldon Hazlet hosts special seasonal activities with advance planning required. "They have a huge Halloween event every year where people decorate their sites (pretty extensively) and there's a haunted house, then kids trick or treat from site to site. The campground also provides pumpkin painting contests and other fun activities," explains a camper.

    Proximity to supplies: Most campgrounds maintain a 10-20 minute drive to retail options. "Walmart is just 5-10min away if needed as well as restaurants, gas station, and other amenities in Carlyle nearby," shares an Illini Campground visitor.

    Varying beach conditions: Swimming areas may have limited facilities. "We were within a few minutes drive of the main lake beach and facilities that include a restaraunt and visitors center. A 7 minute drive gets you into the town of Carlyle which has all the necessities- food, gas and Walmart," explains an Eldon Hazlet camper.

    Tips from RVers

    Full hookup availability: Several campgrounds offer limited full-hookup sites. "If you are needing a full hookup site, make sure you book early!" advises a visitor to Coles Creek Recreation Area.

    Level site considerations: Many concrete pads require minimal leveling. "We stayed in site #7 for one night in the spring. Some sites are spacious, others are pretty cramped," notes an Eldon Hazlet camper, highlighting the variability between sites.

    Shower facility locations: Planning for bathroom access can improve the camping experience. "Unless you have a restroom in your rig, be prepared to walk up to the showerhouse," advises a visitor to Eldon Hazlet State Park.

    Winter camping options: Limited camping spots remain open during off-season months. "I started in the East Spillway Loop as that's all that's open in the winter. Easy bike ride into the town of Carlyle," shares a camper at COE Lake Carlyle McNair Campground.
