    Chicago Northwest KOA accommodates campers with pets in their tent sites, RV spaces, and cabin rentals. The campground enforces a 5 mph speed limit throughout the property and features designated pet areas, including newly added puppy sites with private gated areas for dog owners. Most sites are fairly close together, though the pull-through spaces offer slightly more room for pets to move around. The campground maintains clean facilities with regular maintenance of grass areas where pets can exercise. Several reviews note strict quiet hours enforcement which helps control nighttime barking from visiting dogs.

    Thomas Woods Campground provides pets-allowed camping within the McHenry County Conservation District, with electric hookups and drinking water available for both tent and RV campers. The conservation area offers natural surroundings with hiking trails accessible directly from the campground where leashed pets can explore. The roads and paths throughout the area are well-maintained, though some reviewers note the campground host patrols frequently on a utility vehicle. Lehmans Lakeside RV Resort and Rock Cut State Park also welcome pets, with Lehmans featuring a secure, fenced dog run area and walking paths around their lake. Most campgrounds in the area require pets to be on-leash at all times and owners to clean up after their animals, with waste stations provided at designated areas.

      Hononegah Forest Preserve

      All sites are separated not on top of each other. We’ve been here quite a few times during cooler months and have been very happy with our experience.

      Prairie View Campground - Rock Cut State Park

      Nice Shaded Camping Alcove With Plenty of P&Q

      Prairie View CG is the very first camping oasis you will come across after entering Rock Cut SP from its northernmost entrance, with Highway 173 to the west and Harlem Road to the east. Once you enter the park, you will follow the long winding nicely paved two-lane circuit until you begin seeing the signs highlighting where to go for the various campgrounds. Once you access this road, you’ll come across a small building with a ranger where you will check in, after which, you will pass by a designated dump station before coming around a small bend where you will take your first left.

      The sites begin with #500 and as you circumnavigate the simple circular loop, you will pass by about 2 dozen or so slots that are nice flat paved slots perfect sized for just about any RV or 5th Wheel. There is a single his / her restroom along with trash area at the beginning of the loop just past sites #503 and #504. To access the shower, you will need to go back to the main road and hike it down the road with your towel and toiletries, which I have to admit, is the biggest bummer about this particular campground. If having close access to shower facilities is important to you, then you may want to contemplate staying at other campgrounds here at Rock Cut SP like Staghorn and White Oak, which offer closer proximity.

      One of the greatest assets here at Rock Cut SP is the very massive Pierce Lake, which is great for fishing, boating, kayaking and swimming. To launch your watercraft, you’ll head south to Hickory Hills campground where on the eastern side of this area you’ll be able to find the boat launch. In the Prairie View campground, in addition to restroom and waste disposal, you’ll also have access to running water spigots at each site along with running electric. The small community amphitheather is located centrally just past the campstore and before reaching the Hickory Hills campground. There is an excellent camp store in the middle of Rock Cut SP that offers up ice, firewood, ice cream, snacks, games, limited groceries and a number of other sundries you might need while camping. Additionally, there are 5 shelters that have electricity, with water and restrooms nearby and each shelter available through a reservation system. Two of the shelters (Red Oak and Puri Crest) also have children’s playgrounds nearby.

      Insider’s tips? Here’s a few: (1) IMHO the best sites here at Prairie View CG are those that are located furthest from the main road, for attaining the maximum camping bliss trifecta of less traffic, little noise and more privacy. As such, look at sites #512, #514, #516 and #518, which are all located on the exterior of the circle, thus providing the greatest amount of intimate nature experience; (2) Once you grow weary of trying to conjure up that next meal from the depths of your cooler, fret not, and just head out of the park where you will find a handful of dining options: Tom& Jerry’s, Fresh Start Café, Waffle Shop, Golden Chopsticks Buffet, Sunrise Family Restaurant, Beef-A-Roo (in fact, there’s like 4 of these that the park is surrounded by), but one of my absolute favorites is Green Fire, which is a really nice farm-to-table joint; (3) Got bird watching on your mind? Well, you’re in luck, because here at Rock Cut SP you can spot an amazing array of winged adventurers including bald eagles, American robins, northern cardinals, barn owls, mourning doves, indigo buntings, eastern bluebirds, Canadian geese, red-bellied woodpeckers, brown thrashers and many others; (4) Tired of nature and just want to get some really cool culture in you? Then head just due south of Rock Cut SP to explore Frank Lloyd Wright’s Laurent House, which is simply amazing; and (5) If you come bearing watercraft like canoe or kayak, while Lake Pierce is wonderful and great for fishing, if you want something a bit more challenging, then head due west to the Rock River, where you can drop in from a number of launch sites, however I strongly recommend Atwood Homestead Forest Preserve.

      Happy Camping!

      Hansen's Hideaway Ranch and Family Campground

      Rustic Ranch Retreat Beneath Big Prairie Skies

      Set deep in the farmland west of Oregon, Hansen’s Hideaway blends working-ranch authenticity with simple, countryside camping across more than 100 acres of pasture, red barns and wide-open Midwestern sky. Founded in 1962 and reached by a winding bend off S Harmony Road, this quiet hideout welcomes guests beneath an old-fashion tall wooden ranch gate right out of the Wild West and into a spread of RV loops, tent spaces and shade-scattered meadows where horses graze freely. Sites range from the busier cluster near the main office, which is also where you'll be to the swimming pond, game room, arcade, pavilions and clean restrooms to two quieter, more spread-out loops farther in the property that offers privacy and stillness for those seeking a true escape. Amenities include water and electric hookups, fire rings, picnic tables, a dump station, playground and a small market inside the office. While remote, the campground offers easy access to great hiking at George B. Fell Nature Preserve and Lowden-Miller Forest with excellent kayaking on the Rock River at nearby Castle Rock State Park. Expect big skies, big peace and that unmistakable 'far from everything' feeling.

      UPSIDES: (1) Authentic working ranch setting with roaming horses and wide prairie views; (2) Exceptional peace & quiet thanks to the secluded location; (3) Shaded and spacious RV sites plus open tenting areas; (4) Fun family amenities including a swimming pond, arcade, game room and playground; (5) Clean, well-maintained restrooms and showers; (6) Friendly, welcoming staff; (7) Close to great hiking and kayaking destinations; and (8) If you'd like to get the scoop on what's happening at this CG, swing by the main office for a cup of joe and hang out around the wood-burning stove to chat it up with the owners, fellow campers and working ranchhands.

      DOWNSIDES: (1) Very remote with no nearby services, so campers should arrive fully stocked as it's a decent haul back to civilization; (2) No sewer hookups and limited on-site provisions; (3) The RV area near the office can feel crowded during peak weekends;(4) Amenities show their age in places; and (5) Cell signal varies significantly by carrier.

      Blackwell Family Campground

      Great Stay

      Blackwell has clean bathrooms, offers hiking trails, boating (kayak rentals) or bring your own, fishing, archery, cycling. The gate locks at 7pm but you just call the night guard and he will let you in. They’re only open on Friday, Saturday and holidays. Would definitely stay again. Be aware Winfield Road has a lot of traffic so sites further away from that road are best. Heard coyotes about 3 am both mornings. Rangers were exceptional.

      Castle Rock State Park Campground

      Primitive Perfection @ This Paddle-In Paradise

      For those willing to trade the hum of RV generators for the splash of paddles against the Rock River, Castle Rock State Park offers one of the most unique and rewarding camping experiences in northern Illinois. Located just a few miles south of Oregon - which if you aren't familiar with, is ABSOLUTELY worth exploring, particular in and around Lorado Taft - along scenic Route 2, this park is a natural mosaic of limestone bluffs, sandstone formations, and dense Midwestern forest punctuated by open prairie. Access to the campground, however, comes only by water ... oh yes, this is a TRUE paddle-in site. You’ll need a canoe or kayak to reach the nine primitive campsites that line this quiet stretch of river, each one tucked beneath a canopy of trees that have seen centuries of change and history.

      HIGHLIGHTS: (1) Absolute serenity - the only sounds you’ll hear are the river, the birds, and your own campfire; (2) The boat-in exclusivity means far fewer visitors, granting this spot an unmatched sense of privacy; (3) Rich Native American history surrounds you as this was Sauk and Fox territory, and nearby you can visit the 48-foot Lorado Taft statue honoring Chief Black Hawk (which the adjoining property is actually another SP here in IL that is also very worthy of your camping pleasure); (4) The South Trails(Pond, Oak Ridge, and Fox) offer easy-to-moderate hikes once you paddle ashore and cross Route 2, while the North Trails provide tougher climbs, but the payoff is worth it with breathtaking overlooks; (5) For anglers, the Rock River teems with bass, walleye, sauger and northern pike; and (6) The view from the Castle Rock Scenic Overlook, just upriver from the launch, is one of the most picturesque in all of Illinois.

      LOWLIGHTS: (1) Access is strictly by water - here there's absolutely no vehicles, no hiking path or basically ANY amenity - so plan for wet feet and muddy landings accordingly; (2) Facilities are minimal with just one basic bathroom with a fairly nasty vault toilet (glorified hole in the ground) and no showers; (3) Seasonal flooding can temporarily submerge lower sites near the waterline, so plot out planting your tent carefully; (4) Expect a workout carrying gear up from your kayak or canoe; and (5) Dock availability is inconsistent, particularly in spring and fall shoulder seasons, when the temporary dock may altogether not be present.

      Rolling Oaks Campground

      Old-School Camping with a Whole Lot of Personality

      Rolling Oaks is one of those wonderfully old-school Midwestern campgrounds that feels less like an RV resort and more like a little summer community that has been evolving for generations out here in the rich corn patches of central IL. Family-run since 1969, the sprawling, shady property sits along the Fox River with its very own lake and a decidedly RV-centric personality, where curb appeal is just as important (if not more) than the actual mobile confines people are living in. A substantial portion of the campground is occupied by long-term and seasonal residents, complete with patios, sheds and occasionally elaborate outdoor entertaining spaces, which gives Rolling Oaks an unusual neighborhood feel rather than the transient atmosphere of most CGs. 

      While my earlier review goes into considerably more detail, I thought I’d revisit this campground with a quick topline of HIGHS and LOWS along with a fresh batch of photos.

      HIGHLIGHTS: (1) Water is the star here, with a swimming lake, pool and direct access to the Fox River making this particularly appealing if you bring kayaks, canoes or tubes; (2) Plenty of shade and a mixture of full-hookup, partial-hookup and pull-through RV sites plus tent camping accommodate just about every style of camper; (3) Playgrounds, volleyball, horseshoes and a game room give kids plenty to do without leaving the property; (4) Summer weekends have an almost throwback campground-community atmosphere with dancing, cart rides, farmers’ markets, spaghetti dinners, corn boils and pig roasts; and (5) Being only a few miles from the village of Sandwich makes supplies easy while putting you in prime position for the enormously popular Sandwich Fair (if you manage to time your stay here to coincide with this annual attraction). 

      LOWLIGHTS: (1) The large population of seasonal and long-term campers means portions of Rolling Oaks can feel more like a permanent RV neighborhood than a campground; (2) All that community activity means summer weekends aren't exactly designed for campers seeking solitude and P&Q; and (3) The CGs sprawling layout means the experience can vary considerably depending upon where you land with front sections feel busier and more transient, while areas farther back become increasingly more residential. 

      Insider’s Tip: For the best balance of scenery, shade and quiet, head toward the far side of the lake, away from the busiest weekend activity. And if you're thinking of bringing a kayak or canoe, definitely bring it as direct Fox River access is one of Rolling Oaks' biggest advantages. 

      Happy Camping!

      Pearl Lake

      Late night party central

      The park is beautiful. The water is beautiful. They say it's a gated community, but it's open to the public 9 to 5 daily. At twenty five dollars per person. And then on friday and saturday night, the locals that park here for the summer start their party central including karaoke at the camper next door, and several others. I've never had a camcround with that loud of parties. And it's a weekend event. I like hearing and seeing people having fun but when the manager extends the curfew for the parties she's at (they kind of party hop), it starts to affect the enjoyment of the park. If we had to stay, we'd stay in the S## sites in the back, where you don't hear so much of the partying. And then during the day, the rules began. Kind of like the soup nazi.

    Guide to Union

    Campgrounds near Union, Illinois sit in the rolling prairie landscape of McHenry County, with elevations averaging 900 feet above sea level. The region features a mix of hardwood forests, restored prairies, and small river systems including the Kishwaukee River watershed. Most campgrounds remain open from April through October, with closures during the winter months due to the harsh Midwestern freeze-thaw cycles.

    What to do

    Fishing opportunities: Thomas Woods Campground provides access to fishing ponds within the Marengo Ridge Conservation Area. As one visitor noted, "Great hiking trails, a pond for fishing, private camp sites" with trails directly accessible from the camping area.

    Hiking trails: Rock Cut State Park offers extensive hiking options within its 3,000-acre property. A camper explains, "There is boating and fishing as well as swimming in the lake. The campground staff is very helpful and do a good job at keeping it clean and well maintained even with the large number of visitors."

    Swimming: Sycamore RV Resort provides lake swimming in a maintained beach area. According to a reviewer, "Nice lake for fishing and a beach area for the kids to go swimming... Bathrooms are immaculate and are locked with electronic key cards. Close to DeKalb."

    Wildlife viewing: Woodland and prairie animals are common throughout the area. A visitor at Thomas Woods mentioned, "My 'leashed' dog loves this place, as do I" while exploring the "Beautiful IL woods and prairie" with opportunities to spot local birds and deer.

    What campers like

    Private campsites: Thomas Woods Campground receives praise for its secluded sites. A camper shared, "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, which was nice."

    Clean facilities: Chicago Northwest KOA maintains well-kept grounds. A visitor mentioned, "This campground has really grown on me a lot. My family and i have seen the newer owners clean it up, remodel sites, add new equipment for children and added more activities too! It's really a fun time here OH and the bathrooms are really clean!"

    Convenient location: Multiple campgrounds offer proximity to Chicago while still providing natural surroundings. One camper at Chicago Northwest KOA said, "Far enough from the city lights, close enough to civilization. Cozy, small park with friendly staff and plenty of amenities."

    Lake activities: Multiple properties feature fishing ponds or lake access. A visitor to Sycamore RV Resort noted, "Great fishing and nice beach for swimming. Very nice shower/laundry house."

    What you should know

    Limited showers: Some campgrounds lack shower facilities. At Paul Wolff Campground, a camper reported, "The vault toilets are clean but smell like vault toilets at 95 degrees. There is one very clean flush toilet building but no showers."

    Campsite spacing: Site proximity varies widely between campgrounds. A reviewer at Chicago Northwest KOA observed, "Very nice campground. 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."

    Seasonal restrictions: Most campgrounds operate within limited timeframes. Thomas Woods Campground only offers "Limited to weekend camping, but spread out private-like tent sites."

    Staff presence: Campground monitoring varies between properties. At Thomas Woods, one camper noted, "The campground host needs to lighten up and shes out on the gator every 30 minutes, that gets annoying."

    Tips for camping with families

    Kid-friendly activities: Chicago Northwest KOA offers structured programming for children. A visitor shared, "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."

    Playground options: Lehmans Lakeside RV Resort provides play areas for children. The resort features "a secure, fenced dog run area and walking paths around their lake," making it one of the most dog friendly campgrounds near Union.

    Noise considerations: Some campgrounds enforce quiet hours strictly. A KOA camper mentioned, "There are a lot of activity 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."

    Site selection for families: At Thomas Woods, "We did our first (family of 5) camping trip at Thomas Woods. We were 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."

    Tips from RVers

    Setup assistance: Staff helpfulness varies between dog friendly campgrounds near Union. At Sycamore RV Resort, "When we arrive, the host will bring you to your site and just listen to his directions and he will get you into your site perfectly. I asked if I could bring him on my future trips. I've never parked so easily."

    Site types: Northwoods RV Resort provides full-service sites. A reviewer mentioned, "The sites are pretty big. The campground is not congested at all. The people are very nice. Everyone waves to everyone."

    Utility reliability: Check about electrical service before booking. At Rock Cut State Park, one camper reported issues: "We have a 30 amp trailer. When we got there, the electricity wasn't working. It was 93° on a Saturday."

    Pet accommodations: For those with dogs, Lehmans Lakeside features dedicated pet areas. A visitor mentioned, "Lots of dogs so be prepared for early morning barking," reflecting the pet-friendly nature of many campgrounds in the area.
