    Sycamore RV Resort

    Peaceful Lakeside Pause in the Heart of Corn Country

    There’s something so comforting about pulling into Sycamore RV Resort and seeing the sunlight dance across those two spring-fed lakes, giving you that immediate exhale that only a calm Midwestern campground can bring. The property is medium-sized, incredibly tidy and thoughtfully laid out, with full-hookup RV sites circling the water, a small sandy beach for summer splashing, clean restrooms and showers, simple playgrounds and EZ walking loops that make it feel both manageable and welcoming for families. The boys were in heaven the next morning when we drove over to Elleson’s Bakery for fresh homemade donuts still warm from the oven. Later we wandered through historic downtown Sycamore during Pumpkinfest, taking in the decorated storefronts and carved pumpkins lined up like a little parade. Back at the RV Resort, from what we saw, the best campsites are any of the lakeside slots on the western shore because they offer the prettiest sunrise views and the quietest pockets of the resort. Overall, I’d absolutely recommend this campground for families thanks to its peaceful lakeside setting, its clean and convenient amenities and its proximity to a charming small provincial Midwestern town that makes even a simple weekend feel memorable.

    Holiday Acres Camping Resort

    Country Calm with a Dash of Classic Campground Fun

    The moment we pulled into Holiday Acres, that cozy ‘old-school campground’ feeling washed over us, with tall trees, winding lanes and a big, friendly welcome from the office that instantly made the boys sit up and take notice. The campground is beautifully laid out with roomy sites, full hookups, a well-kept swimming pond, mini golf, a little camp store and restrooms that were impressively clean for a busy family spot. After a long drive, the boys made a beeline for the playground and the pedal carts, and later that night we all sat under the string lights eating ice cream sandwiches from the camp store while fireflies blinked and buzzed through the trees. If you’re a family looking for somewhere safe, shaded and EZ-going with just enough activities to keep the kids happily worn out, this place absolutely fits the bill. Highly recommended for its friendly atmosphere, great kid-focused amenities and peaceful, wooded setting.

    Camp Reinberg

    A Forest Preserve Escape for the Whole Family

    From the moment we pulled into Camp Reinberg, our entire family felt something was unique and different about the peacefulness that you immediately encounter when arriving here to Camp Reinberg – it was the kind of quiet that settles over you long before the bags are unpacked, which felt remarkable considering how close this little retreat sits to suburban Palatine. This Forest Preserve of Cook County campground is modest in size with a mix of tent pads, a very small circuit of RV-friendly sites and several modern cabins that give it the feeling of a thoughtfully managed woodland outpost rather than a crowded complex. Amenities are simple but well-cared-for, including clean restrooms, hot showers, shaded picnic areas, a proper indoor camping kitchen and dining hall as well as a large open field for play complete with an enormous bonfire pit and BBQ grill area with direct access to the miles of hiking paths that wind through Deer Grove Forest Preserve. Our favorite moment came just before sunset when the boys darted between the oaks spotting chipmunks while we lingered at the picnic table with a thermos of hot cocoa, savoring the calm and popping in extra marshmallows for full effect. For families, this campground is genuinely recommended thanks to its safety, gentle trails and close-to-town convenience with the best site choice being either one of the tent pads along the wooded northeastern edge (sites#6-10) or the northernmost corner of the RV loop if you’re looking for a spot for your rig (#2-4), where the privacy and tree cover make the stay feel much more like a deep-forest escape.

    Love this quaint smaller campground, close to home although you feel like you're way up north! Clean restrooms showers! Walking trails with preservation.

    Paul Wolff Campground

    Good place for a night or 2

    First, you have to make reservations in advance online. The website says otherwise. They are spacious sites and well maintained the water. Spicket are a significant distance from each campsite so come prepared for that.

    Rolling Oaks Campground

    Always amazing

    This was my family's campground before my grandmother passed when I was 7. From then till a few years ago I hadn't been back. The first time getting back was definitely a trip down memory lane. Now I try to get a campsite at least once a year. It's always quiet and peaceful & the staff is always willing to help make sure that you have the best experience possible.

    Lehmans Lakeside RV Resort

    Location is ok but staff are not

    The worst thing about this campground is that the well water contains rust that affects your entire trailers water system. Staff did not tell you beforehand that your trailer will be destroyed. I’ve stayed here seven months and have had my water repeatedly cut off without notice.

    Plum Grove at Rock Cut State Park

    Tired old park

    Not a level site in sight. Holes and washout channels throughout the campground. The pit toilets available offseason are run down and shabby at best. At least there’s TP. I’ve been coming here for 50 years and while some improvements have been made, and the concession area is nice, the campground makes me sad.


Guide to Union

Camping options near Union, Illinois include seasonal and year-round facilities within a 30-minute radius. The region's landscape features a mix of forest preserves and prairie terrain at approximately 900 feet elevation, creating diverse habitats for wildlife. Summer temperatures typically range from 65-85°F, while spring and fall camping offer more moderate conditions with occasional rainfall that can affect site conditions.

What to do

Fishing opportunities: Chicago Northwest KOA offers family-friendly fishing, while nearby campgrounds provide access to stocked ponds. "We stayed at site 37 and enjoyed our stay. There are vault toilets but the large number of big RVs meant they were not used often leaving them almost like our private restrooms," notes one camper at Paul Wolff Campground.

Hiking trails: Multiple hiking trails at varying difficulty levels run through the region's preserves. "There are miles of trails. On one hike we were on paved, sifted gravel, grass and single trek trails. There are a lot of loops giving you options. When we left we still hadn't hiked all of them," reports an Art S. at Paul Wolff Campground.

Swimming access: Some facilities maintain dedicated swimming areas or beaches for hot summer days. "The pool area was nice, but tons of kids. CG was very kid friendly, with tons for them to do," observes a reviewer about Chicago Northwest KOA.

What campers like

Privacy between sites: Site layout varies significantly by location. At Thomas Woods Campground, "Most of the tent spots are spaced out enough to provide privacy and quiet. Firewood is cheap on-site and delivered to your site on demand," explains Matt K. Another reviewer notes, "I stayed in one of the tent camping sites with a little walk up (parking for a car available about 50 feet away). Nobody else was camping within sight of me."

Clean facilities: Many campers highlight maintenance standards. "The campground is beautiful wish it was open more than the weekend's," states one visitor to Thomas Woods. Another reports, "Bathrooms are immaculate and are locked with electronic key cards" at Sycamore RV Resort.

Wildlife viewing: The natural settings attract diverse wildlife. "We hiked the trail and saw a mother deer feeding her 2 babies. Hard to belive that there is hiking trails like those in such a densely populated area just outside elgin, il," reports a camper at Paul Wolff Campground.

What you should know

Reservation requirements: Most campgrounds in the area fill quickly during summer months. "Stayed here for a week, nice clean campground, quiet and beautiful lake for fishing, close to town, but yet just far enough out," notes a reviewer at Sycamore RV Resort.

Seasonal operations: Check operating dates before planning trips. "I've been here two other weekends. Generally quiet and many of the tent spots are spaced out enough to provide privacy and quiet," reports a Thomas Woods camper.

Shower availability: Facilities vary widely between campgrounds. At Rock Cut State Park, "Shower buildings were clean enough, but very old with bad shower heads." Another camper mentions, "We stayed in the White Oak area and used our tent. This location was close to the shower house."

Ambient noise: Some campgrounds experience noise from nearby roads or railways. "You can hear the highway at night which kinda takes away from the nature vibes but overall I was very happy with our one night stay," reports a visitor to Rock Cut State Park.

Tips for camping with families

Playground access: Several campgrounds feature play areas for children. A visitor to Chicago Northwest KOA observed, "Did a quick stay with the kids for a Friday and Saturday night. Plenty for the little kids to do, and the text message communication was great with regards to weather updates or any goings on around the campground."

Family-oriented activities: Scheduled events often target younger campers. "Lots of activities for kids on the weekends. People are nice to you. Plus they have a quiet time at night. So people and kids can go to bed without a bunch of noise," shares a reviewer about Chicago Northwest KOA.

Child-friendly water features: Several facilities maintain swimming options. At Northwoods RV Resort, "The pool is very clean and the staff helped us pick a better site upon arrival. They also have a very pretty river to fish."

Tips from RVers

Site access considerations: RV site configurations vary across facilities. At Chicago Northwest KOA, "It's on the smaller side and the RV sites are a little close together but they have it set up where your RVs doors open on opposite sides so it gives a little privacy."

Electric reliability: Power capabilities differ between campgrounds. A reviewer at Rock Cut State Park shares, "We stayed at site 4 which is electric hookup and it was a huge area! The kids had so much space to run around and explore. They loved the well pump."

Seasonal hookups: Water access changes seasonally at some locations. "We live less than five minutes from Rock Cut and wanted to test out our pop up camper. It's off season so the showers were not open yet but there were open toilets," notes a camper.
