Best Campgrounds near Marengo, IL

Marengo, Illinois provides several established campgrounds within a 30-minute drive of town, with camping options ranging from basic tent sites to full-service RV parks and cabins. Thomas Woods Campground at Marengo Ridge features both tent and RV camping with electric hookups and private wooded sites. Other options include Chicago Northwest KOA in nearby Union, which offers cabin rentals and family-friendly amenities, and Lehmans Lakeside RV Resort with year-round availability. The region includes multiple conservation areas and forest preserves that accommodate various camping styles while providing access to hiking trails and outdoor recreation.

Seasonal considerations strongly influence camping in the Marengo area, with most campgrounds operating fully from May through October. Thomas Woods Campground is primarily open on weekends only, limiting mid-week access for spontaneous trips. Many sites require advance reservations, especially during summer months when local campgrounds reach capacity quickly. Most tent sites in the area feature raised platforms for flat sleeping surfaces, while RV sites typically offer 30-50 amp electrical hookups. Water access comes primarily from hand pumps at conservation district properties. "The mosquitoes are unbelievable, it made hiking in the woods impossible. We have given it 3 tries now over a few years and the mosquitoes have gotten worse every year," noted one camper about summer conditions at Thomas Woods.

Campers report high satisfaction with the privacy and natural setting at Thomas Woods Campground, particularly appreciating the secluded walk-in tent sites set back from the main road. The wooded camping areas provide shade and separation between campsites, creating a more isolated experience despite being relatively close to Chicago. Hiking trails receive positive mentions, with Marengo Ridge offering both wooded paths and prairie walks accessible directly from the campground. Several visitors mentioned appreciating the firewood delivery service at Thomas Woods, where staff will bring purchased bundles directly to campsites. Noise levels vary by location and season, with weekend camping typically being busier but still relatively quiet compared to larger campgrounds closer to Chicago. A recent review noted, "The campground is small the RV sites are shallow and close to the road but otherwise most are fairly private."

    We had such an enjoyable time at Ottawa Lake Campground.

    Escape the everyday and immerse yourself in nature at Ottawa Lake Campground. Nestled in the heart of the Kettle Moraine State Forest, this welcoming retreat offers lakeside fun, scenic hiking trails, the quiet beauty of a true Northwoods experience, all without a long drive.

    We have visited the Campground 5 times this year already, we love hiking all the trails in the Kettle Moraine Southern Unit.

    Pettits Lakeview Campground & Bar

    Family Friendly Lakeside Campground

    Pettit’s Lakeview Campground & Bar is the kind of place where family camping meets lakeside fun with a lively twist, sitting right on Lake Koshkonong with beautiful sunset views and easy boat access. My kids loved the playground while the adults enjoyed Friday fish fries, live music and the laid-back bar that doubles as a social hub, creating a strong community vibe with theme weekends and plenty of laughter. That said, it’s definitely more “festival” than “quiet forest” with sites being closing together, weekends can get noisy with karaoke and bar traffic, and shade is limited, so if you’re looking for peace and birdwatching, this isn’t it, but for families who don’t mind a little bustle, it’s a fun and memorable spot.

    Milton-Madison SE KOA

    KOA Close to Lake Koshkonong

    With 2 kids to mind, I found the Milton-Madison SE KOA to be one of the most family-friendly campgrounds we’ve visited, with something for everyone to enjoy. With over 200 sites, the campground is clearly geared toward RVs and fifth wheels, but it also offers a few cabins and tent sites, giving families different ways to stay. The kids were thrilled with the heated pool that even has a waterfall, the playgrounds, gaga ball, arcade, and weekend rides like the barrel train and hayrack.  In short, there was always something to keep them entertained while I could actually relax. I appreciated the practical touches like clean restrooms and showers, laundry facilities, a well-stocked market and a clubhouse with plenty of space to gather. My husband loved that Lake Koshkonong was right nearby for fishing and paddling, and we all enjoyed exploring Milton’s small-town restaurants with Mary’s Café for biscuits and gravy that was a huge hit and Frederick’s Supper Club, both of which made for a special night out. The Riggio family, who run the campground, were some of the kindest hosts we’ve met, which made the whole experience feel extra welcoming. While I do think the tent sites and cabins are a bit pricey for what you get, the number of activities, amenities, and nearby conveniences made it worth it for the memories we created together. For families looking for a lively, activity-packed camping trip, this KOA is a great choice.

    Lakeland Camping Resort

    Lakefront Fun

    As a mom, I found Lakeland RV Campground in Milton to be the kind of place where the whole family can truly unwind and have fun together. Set along Lake Koshkonong this place was bursting with energy and feels more like a summer resort than a traditional campground with over 270 full-hookup sites and cozy cabins for families who don’t have an RV. The kids had endless options to keep them busy from 2 swimming pools, a sandy beach, playgrounds, mini golf, sports courts, and even planned activities and themed weekends and I loved the convenience of the camp store, laundry, fitness center and clean facilities. In the evenings, we enjoyed gathering around the campfire under the stars, and during the day we ventured onto the lake for kayaking and fishing, which felt like a little adventure just steps from our site. It was also nice knowing that if we wanted a change of pace, Milton and Janesville offered small-town charm and great dining and Madison wasn’t far for a day trip. My mom tips? Book a site away from the pools if you want peace and quiet, treat yourself to dinner at Fredrick’s Supper Club, sneak out early for a serene paddle on the lake, and don’t worry if you forgot gear as nearby shops have you covered. Lakeland made it easy for me to relax while my kids had a blast, and that combination is what makes it such a special family getaway.

    Yogi Bear's Jellystone Park at Fort Atkinson

    Nostalgic Campground

    As a mom, I can honestly say that Yogi Bear’s Jellystone Park at Fort Atkinson is one of those rare campgrounds where the kids are entertained from morning till night and parents can actually relax a little too. The whole place feels designed with families in mind: colorful playgrounds, themed weekends, wagon rides, character visits from Yogi and Boo Boo, and a pool with splash zones that keep little ones happy for hours. Our campsite was clean and level, with options for full hookups or cozy cabins if you’d rather skip the RV, and the bathhouses were spotless, which is something I always look for. What I appreciated most was the balance: the kids could run from the jumping pillow to the mini golf course to the craft barn without ever getting bored, while my husband and I enjoyed sitting by the campfire or joining in on family activities like outdoor 'movies under the stars.' The campground store was well-stocked with snacks, s’mores supplies, and those 'oops, we forgot it' supplies, which saved us more than once. And while there’s plenty to do onsite, being near Lake Koshkonong and Fort Atkinson means you can easily slip away for a day of fishing, boating, or exploring. For me, the best part was watching my kids’ faces light up during the evening hayride, sticky with marshmallow, waving at Yogi like he was a celebrity that felt like the kind of wholesome, memory-making trip I hope they’ll look back on for years.

    Milton-Madison SE KOA

    Solid KOA Experience

    The Milton-Madison KOA is one of the larger campgrounds in the KOA network, offering over 200 sites with a mix of full hookups and water/electric-only hookups, along with a selection of pull-through and back-in options, gravel or concrete pads, and some upgraded patio sites. While primarily catering to RVs and fifth wheels, the campground also has about a dozen tent sites and half a dozen cabins. Amenities are extensive, ranging from an in-ground heated pool with a waterfall and two-story patio deck, hot tub, clubhouse, market store, snack shack, arcade, meeting and TV rooms, multiple restroom and shower facilities, laundromat and Wi-Fi, to a wide variety of recreation such as basketball, volleyball, shuffleboard, horseshoes, baseball, disc golf, playgrounds, gaga ball, hayrack rides, barrel rides, train rides, and nature trails. Guests will also find a Kamp K9 dog area, golf cart and bike rentals, propane refill station, firewood, and plenty of seating throughout the grounds. Just minutes away, Lake Koshkonong offers excellent kayaking, canoeing and fishing. For dining, nearby Milton serves up hearty Midwestern fare, from Mary’s Café’s biscuits and gravy to Paul Revere’s homemade pies and the upscale Frederick’s Supper Club, known for its prime rib bites and Diablo pasta. Insider tips include enjoying the warm hospitality of the Riggio family hosts, taking a short drive to Madison for big-city attractions, noting that tent sites - though equipped with water and electric - feel basic and pricey, and being aware that cabin rentals also run higher than average. Thankfully, Milton’s local shops, grocery stores, and hardware options make resupplying convenient, rounding out a destination that’s both activity-packed and well-situated for Wisconsin adventures.  Overall, my family and I really enjoyed this place and would definitely come back!

    Ottawa Lake Campground — Kettle Moraine State Forest-Southern Unit

    Close to "home" beautiful sites

    We've been full time RVers for 4 years and this is a beautiful campground close to "home". We stay here a couple of times each year for doctor and dentist appointments, visiting family and friends, and general relaxation.

    Fish Lake Beach Camping Resort

    Not communicable, fraud administration

    I reserved 5 nights, paid in full. After just one night, management cancelled my stay because my service dogs(Maltese) supposedly barked. I was fully cooperative, kept them quiet, and even documented this in emails. There was a stray cat near my RV that caused the issue, but instead of solving it, they forced me to leave. No refund for 4 nights. This is unfair, discriminatory, and against ADA law.
