  Hennepin Canal Lock 21 Campground

  Nice quiet place

  Water was available on my visit 10-7 thru 10-10. The place is clean and well kept, including the pit toilets. Plenty of hiking along the canal and 10 miles away from most stores. Fee is $8 however if you’re an Illinois resident over 62 camping is free Sunday through Thursday nights.

  White Pines Forest State Park Campground

  First time at a campground in Illinois

  Nice Short walks in the woods. You can link trails together to go farther. Some signs for cross country ski trails.  Most of the sites are not flat and one in front of the other so be prepared for that. If you go after harvest be prepared to hear a grain dryer or other from the farm nearby all day and night. There’s a train you might hear a couple times in the night. Pretty quiet otherwise for other campers. Shower house had nice hot water. Restaurant was nice for dinner. The gift shop is cute. Looks like they have a dinner and show around the holidays at the restaurant. They could use extra signs to say where camping is right when you pull in otherwise you’ll end up at the restaurant or some better signs in the campground. Overall we will be back to select sites select times of year.

  Johnson Sauk Trail State Park

  Trails, Tales & a Big Round Barn at Johnson Sauk Trail State Park

  If you like your camping served with a side of quirk, Johnson Sauk Trail State Park near Kewanee, Illinois, delivers in spades. First impressions are of rolling hills, shady hardwoods, and wide-open prairie that feels like someone took a painter’s brush to the Midwest and got carried away. It’s big, it’s woodsy, and it has just enough old-fashioned charm to make you think you’ve stumbled into a summer postcard here in the heart of the Prairie State. Families and weekend wanderers flock here, but the atmosphere stays laid-back and the kind of place where you can still hear the wind in the trees over the laughter and screaming of kids chasing fireflies.

  The campground itself is no slouch, with more than 70 sites ranging from rustic tent pads (25 in total) to electric hook-up spots that keep RVs humming happily. Sites are generally roomy and shaded, each with picnic tables and fire rings that dare you to try out your best s’mores engineering skills. Bathhouses are clean and close, with flush toilets and showers that (miracle of miracles) actually have good water pressure. Roads are paved and very easy to navigate, though keep an eye on turns if you’re wrangling a bigger rig. Pets are welcome, kids have plenty of room to roam, and the general feel is safe and easygoing.

  And then there’s the Ryan Round Barn, the park’s crown jewel and conversation piece. Built in 1910 by Dr. Laurence Ryan, who was a local physician with a big brain and apparently had a thing for circles, this 180 degree structure is one of the largest round barns in the entire country. This wooden wonder stands 80 feet tall and 85 feet across, with four levels that once housed 50 dairy cows, horses, and enough hay to feed a small army. Walking through it feels like stepping back in time, and even kids who ‘don’t like history’ will be impressed once they realize it’s basically a giant barn spaceship from 100 years ago.And then there’s the Ryan Round Barn, the park’s crown jewel and conversation piece.

  Outside the campground, Johnson Lake offers paddleboat rentals, fishing piers, and calm waters for paddling, which is ideal for wearing out the kids while you pretend you’re training for a kayak marathon! Trails wind through forest and prairie with wildlife sightings being frequent enough that you’ll start feeling like you’re starring in your own nature documentary. When hunger hits, Kewanee is just down the road, with options ranging from old-school diners to pizza joints. And don’t skip The Coop, a local gem in the hamlet of Annawan with an ice cream parlor and baked goods like cinnamon rolls, iced cookies and chocolate chunk brownies so good you’ll briefly consider moving to town just to live closer.

  Insider tips? Yep, here’s a handful: (1) Book a site in the lake loop(of which there’s some 7 or slots to choose from) for quick access to Johnson Lake, where despite a short trek to the water’s edge, you’ll get fewer complaints from the kids when it’s time to haul gear to the water and you’ll also be treated to unbeatable sunset views from one of the scattered benches along the lakefront; (2) For food, check out Cerno’s Bar & Grill in Kewanee, which was established in 1898 BTW and feels like you’re stepping back in time for massive burgers and a family-friendly vibe, Good’s Furniture for surprisingly solid sit-down meals (yes, furniture and food under one roof), and The Coop for ice cream and baked goods that will tempt you back two days in a row; (3) Don’t miss touring the Ryan Round Barn with it’s four stories of history, architecture and oddball charm that kids and adults alike will find fascinating. Just remember: it’s round, so if you get lost inside, maybe camping isn’t your sport; and (4) Bring a kayak or canoe for Johnson Lake as the calm water is great for families, fishing will likely net some channel catfish, largemouth bass and white crappie and you’ll likely spot turtles, herons and maybe even a beaver supervising your paddling skills.

  Happy Camping!

  Geneseo Izaak Walton League Campground - Members Only

  Hidden Gem Along the Hennepin Canal

  This is the Geneseo Chapter of the Izaak Walton League of America, which coming across one fine Autumn day, I was completely unaware of this organization, which apparently is America’s oldest and most successful conservation organizations. This particular chapter in Geneseo was chartered back in 1952 and shortly thereafter founded Ike’s Park located right along the Hennepin Canal, which features among other things: picnic facilities, fishing, boating and kayaking, a boat ramp, handicapped accessible fishing pier as well as a community lodge that you can book in advance, in addition to a primitive style campground offering up some 20 or so sites on a first-come, first served basis.

  To put it bluntly, this place is incredibly simple and basic, which is its beauty in a nutshell. This undiscovered little gem will make you feel as though you’ve just hit the primitive camping lottery jackpot as very few folks outside of Geneseo even know of this place. So if you’re coming from slightly further afield, you’ll appreciate getting in on something special. Upon arrival from Route 82, which if you are coming from the nearest major highway of I80, you’d be heading northbound, you need to simply hang a right onto a very modest gravel road that has an immediate declining slope upon entry. Once you turn into Izaak Walton Park, you’ll feel embraced by something truly special with mature maples and oaks surrounding you before coming across a sign marking this territory as Ike’s Place with the community lodge on the right. If you continue on, just about 30 yards further you’ll come across the self-check-in kiosk where you just need to fill out the required information and drop your$10(member) or$20(non-members) in an envelope and you can set up wherever you’d like.

  As you are literally right next to the Hennepin Canal, you’ll want to set up as near the canal as you can get, although, you could sit back a bit further south if you’d like under the canopy of a mature treeline. Beyond the beautiful, scenic riverview, there’s just a couple of community shelters, basic restroom facilities with vault toilets, a fishing pier and a large area that faces a larger swath of the Hennepin Canal that for a short bit resembles a lake, although when you are on the water, you’ll learn it’s just the bend in the river. Here at Izaak Walton Park alongside the property immediately to the south, Geneseo Prairie Park, there’s lots of decent hilly hiking trails to keep you occupied. And of course, if you’re an angler, you’ll appreciate the quick and easy access to casting a line where you’ll be able to catch panfish, small- and large-mouth bass as well as catfish.

  Insider’s tips? Here’s a few:(1) While you are north of Geneseo, you shouldn’t have too much problem with cell coverage out in these parts– we got 4 bars with Verizon and 3 bars with AT&T;(2) Not all of the sites are level, so you definitely want to check out a number of the sites before deciding upon which to choose from– where you’ll also want to keep in mind that not all of the sites have electricity, so either plant yourself near an outlet or bring a long electrical cord;(3) While there is a dump station on-site, when we were there, it was locked, so while we were able to place most of our trash in the garbage receptables, be prepared to haul yours out with you before leaving; and(4) You’ll want to take note that you are sitting alongside the Hennepin Canal, which if you haven’t been to before, provides about 100 miles worth of some pretty amazing slow-moving current that is excellent for kayaks and canoes, so if you’ve got one, bring it, but if not, the good folks at Geneseo Campground just due north of this location across the river will rent you one.

  Happy Camping!

  King's Campground

  Where Fireflies & Faith Meet Fresh Air & Farmland

  As a mom camping with my husband and kids, I loved how this Christ-centered campground felt both safe and family-friendly, with roomy sites that offer shade, fire pits, picnic tables and clean bathhouses close enough for those urgent kid trips. The layout makes it easy to relax while still keeping an eye on little ones and the amenities, whether tent pads or RV hookups, make setting up simple. What really stood out was the nearby fun and educational activity for kids, like a nature trail, nearby working farm, local park or our visit to Blackhawk Statue near Lorado Taft that gave the kids both excitement and a learning moment. At the end of the day, this is the kind of place where parents can unwind by the fire while the kids fall asleep happily worn out from their adventures.

  Summit Campground - West Lake Park

  Nice Break

  We are headed to North Carolina and needed a break from the back-to-back travel days. This campground was clean and quiet while we’re were there. We did stay from Monday to Wednesday so it might be busier on the weekends.

  Sac-Fox Campground, Scott Co Park

  The Brady Bunch of Campgrounds

  SOC-Fox Campground is like the middle child in a family of seven - yes, count 'em seven - campgrounds within Scott County Park. Think Brady Bunch, but with fire pits and RV hookups instead of bell bottoms and avocado-colored kitchens. It’s not the flashiest sibling, but it’s got that reliable Midwest charm that makes you go,'Yep, it's not the most attractive, but it will get the job done.' First impression? Clean, organized and incredibly less chaotic than you’d expect from the Jan of the camping family.

  The sites here are roomy, shaded, and well-behaved, just like campers who say 'please' and 'thank you' everywhere you go, well, because you're in the Midwest. You’ve got a mix of electric and FHU options, so everyone from RV royalty to tent campers with coolers full of questionable lunch meat can settle in comfortably. Roads are wide enough that you won’t have to close one eye and pray when maneuvering your rig. Bathhouses? Shockingly nice. Like, did a spa consultant sneak in here when no one was looking?!  Nice. Fire rings and picnic tables come standard, and the pet-friendly vibe means your dog will probably make more friends than you do.  There's some shade, but most of it is on the treeline on the perimeter.

  And let’s talk about Scott County Park itself, which is like the Disney World of county parks. You want hiking? Got it. Equestrian trails? Saddle up. Disc golf? Fore! Playground for the kids? Absolutely. And then there’s the aquatic center. Not a pool. Not a splash pad. A full-on aquatic wonderland with waterslides, diving boards and enough chlorine to strip a small car of paint. Meanwhile, other campgrounds are out here bragging about their kiddie swings. Weak, right?!

  Insider Tips?  Here's a handful: (1) Shady sites near the woods are perfect for naps and hiding from the in-laws, while open sites are better if you need your daily satellite news fix; (2) Hungry? Roll into nearby Eldridge for The Rustic Ridge, where the burgers are taller than your nephew’s science project and fries are an entire food group all to itself; (3) Kayak fans can float the Wapsipinicon River where it’s calm, scenic and you’ll get to wave at locals fishing with that 'I’ve lived here since 1842' energy; and (4) Don’t skip the aquatic center as your kids will cannonball themselves into exhaustion while you finally finish that camp chair beer in peace.

  Happy Camping!

  White Pines Forest State Park Campground

  Decent getaway from the city

  Cedar Ridge campground: stayed during the week because weekends were all booked. Had the place basically to myself.

  The sites: not very private, and most are one behind the other, so you’ll be going through a campground to get to the main road if you choose one in the back. 

  Atmosphere: There are trains that pass nearby (not constantly), and I could hear some campers from the Sunny Crest campground. Neither were obnoxious, and overall, it was relatively quiet. 

  Wildlife: Turkeys wandering around, lots of different birds, I heard coyotes hooting and hollering in the distance, and an opossum wandered into my site while I was sitting by the fire. 

  Other notable items: Grab wood on the way there from a neighboring home/farmstand. There wasn't anywhere to purchase wood inside the property. 
  There are showers here. I'm not sure if they're open year-round, but the campground is. 
  The hiking trails are fun.
