Best Campgrounds near Trenton, IL

Campgrounds in the Trenton, Illinois area primarily cluster around Carlyle Lake, the largest lake in Illinois, with a mix of developed facilities and natural settings. Eldon Hazlet State Recreation Area provides cabins and both powered and non-powered campsites through its Illini Campground, while several Army Corps of Engineers campgrounds like Dam West, Dam East, and Coles Creek Recreation Area offer additional camping opportunities around the lake. Most campgrounds accommodate tents, RVs, and some feature cabin rentals, with accessibility options ranging from boat-in sites to drive-up convenience for larger vehicles.

Seasonal considerations affect camping experiences throughout the region, with most campgrounds operating from spring through fall, typically April through October. Dam West Campground maintains a season from March 30 to October 30, while Boulder Recreation Area runs from April 13 to October 12. Flooding can occasionally restrict access to certain areas, particularly during spring months. The campgrounds typically feature electric hookups, with many offering water access directly at sites or nearby. Several developed campgrounds provide shower facilities, though availability varies by location. One visitor noted, "This is our favorite campground with full hookups, reservable sites, walk up sites, and all sites are large! Full hookup sites are booked solid so make sure you go online 6 months out or you are out of luck."

Lakeside camping receives consistently high ratings from visitors, with many mixed-use campgrounds providing direct access to Carlyle Lake's shoreline. Concrete pads at many sites accommodate larger RVs, while shade trees provide relief during summer months. The Dam West area includes amenities like playgrounds and amphitheaters, with biking and walking paths connecting various recreation areas. Campers frequently mention the wildlife viewing opportunities throughout the region. As described in feedback on The Dyrt, "This campground is perfect for taking long walks and bike riding. There are two swimming pools close by but none in the campground."

    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!

    Dam East - Mcnair Campground

    Peaceful and quiet

    Another really nice COE campground. With our pass for seniors, we only paid $10 for electric. The sites were a little closer together than normal COE’s but still plenty of room. Water spicket’s were placed throughout the park but not at each site. There was a lake with a swim beach and two playgrounds. Sites were very level. Nice and shady. Close to town. Well maintained showers.

    Great place to stay overnight

    The owner, Barb, was very friendly and helpful. We had a pull through just for overnight, and it was perfect.
    The park appeared well taken care of, and the pool looked clean.

    Love's RV Hookup-Hamel IL 578

    Good for a truck stop, busy and loud

    Easy reservation system online. $60 is a bit pricey for one night. Electricity and water at each spot which are concrete slabs. Typical super busy truck stop with bright lights and lots of action but safe and convenient.

    Boulder Rec. Area - COE Campground

    Spacious and clean

    Campground was well maintained with spacious campsites. I tried to get a spot on the water but they were all reserved, they looked really nice so I would try to get it in the future. Showers were nice with air conditioning. I would say this is more of a campsite for RVs but it worked fine with our tent. Host was nice and helpful.

    Ok for a one night stay

    The owners are friendly. The pool is well-maintained and pleasant. The campsite is an old KOA frozen in time. It's clean but dated. Water and electricity are available on site with an old picnic table. Only one bathhouse (toilet, shower) is a bit far from our site.

    Cahokia RV Parque

    Excellent urban RV Park

    Just minutes across the river from St. Louis. They have a shuttle to the various tourist attractions, just ask the staff at the office for details. The staff are friendly, the facility is clean and professional. Will stay again since I am in St. Louis every month.

    Price is comparable. Yes, it is an urban campground in a sort of run down area. It is what it is. But it was safe, clean and professionally ran.
