Chain O' Lakes State Park offers multiple pet-friendly campgrounds near Wonder Lake, Illinois, with sites spread across 6,500 acres in northeastern Illinois. Located at elevations between 735-790 feet, the park experiences warm summers and cold winters, with campgrounds closing seasonally from late October through early April. The park connects to the Fox River and 15 lakes, with 44 miles of shoreline accessible from various camping areas.
What to do
Kayaking the waterways: Turner Lake South Campground provides access to multiple lakes connected by channels. "I love to kayak through here because I don't need to paddle through the river unless I'm feeling competitive. I enjoy this route for the wildlife and nature scenery. I've seen beavers, minks, ferrets, and sand cranes on my two trips so far," notes camper Cora M.
Horseback riding excursions: Prairie View Camping Area offers access to designated horse trails and rentals for visitors without their own horses. "There are horse rentals and a trail designated as horse friendly," reports Art S. Another camper mentions, "There is horse riding here as well. The views are breathtaking."
Fishing multiple lakes: Fish from shore or rent small fishing boats at several locations throughout the park. "The lake was very nice. We were able to kayak but be careful getting the kayaks in. Stairs down to the pier and the bottom of the lake is very mushy. The water was very clear and you could see the fish swim by," shares Julia B. from Turner Lake South.
What campers like
Private, wooded sites: Fox Den Campground offers more secluded camping options with natural separation between sites. "Fox Den is superior to Honeysuckle Hollows because each site has an individual electric post. Sites in Honeysuckle have electric posts too far from parking pad. Fox Den also has more space between sites, more level pads and each site is tucked away with trees," explains Debra M.
Clean, accessible facilities: Most campgrounds feature well-maintained bathrooms and shower facilities. "The bath house was clean. The sites were large and the fire pit and table were in good condition," shares Michelle M. about Fox Den. Another camper notes, "Facilities are clean and well lit. Fire pits are slightly raised steel troughs with a heavy adjustable grill."
Winter camping options: While most Illinois state parks close completely in winter, Illinois Beach State Park remains open year-round for hardy campers. "We love camping here. It truly feels rural. Small shower house but water pressure is amazing. It's always quiet and the view is beautiful," reports Kaitlin M., though she warns, "Bugs were awful this stay."
What you should know
Gate closure timing: The main entrance gates lock at 10:00 PM sharp with tire shredders that prevent late entry. "The gates close at 10:PM and there are tire shredders, you can leave but you can't get back in… unless you want to walk 2+ miles in the dark," warns Brian O. from Turner Lake South.
Campsite reservation system: Mud Lake East Campground sites fill quickly during summer weekends. "While these sites are usually slated for walk-ups on the weekends, it seems like a lot of people go early on Thursday or even Wednesday to secure their sites for the weekends," advises Marisa A.
Alcohol restrictions: Unlike private campgrounds, all Illinois State Parks enforce no-alcohol policies. "The only big minus is the full hook ups fill up fast no spur of the moment camping unless it is early or late in the season. The other thing is ALL Illinois State Parks are now enforcing a no alcohol policy even if you are on your own site," explains Jeanne M. from Fox Den Campground.
Tips for camping with families
Beginner-friendly options: Thomas Woods Campground offers smaller, more manageable camping for families new to outdoor activities. "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," shares Emily L.
Wildlife viewing opportunities: Schedule morning walks when animals are most active. "The extensive trail system offers multiple options with wide, crushed gravel pathways and paved sections suitable for families. Several trails connect throughout the park, providing access to wildlife viewing areas where campers can spot beavers, minks, and sand cranes," says a visitor to Turner Lake South.
Tick prevention essential: Pack proper clothing and tick removal tools, especially with small children. "SO many ticks. With a baby crawling that needed to be set free, we were constantly doing checks. Luckily our screen house pop up on a tarp that was sprayed ahead for tick repellent plus a blanket on top of that did the trick, but they literally fall out of the trees into people!" warns Meg from Honeysuckle Hollow.
Tips for RVers
Electric hookup considerations: Honeysuckle Hollow Campground requires careful site selection due to electric hookup placement. "These sites share an electric box. Some spaces the box is further than 30 feet from the pad. A lot of the spaces are also crowded together. Recommend sites 23 to 46 for spacing and electric distance," advises Debra M.
Site leveling challenges: Bring extra leveling blocks as many sites have slight grades. "We originally booked 96 but could not extend our slide because of large trees on either side of the pad and then the electric was about 50 feet away. Moved to 50 one of the nicest spots," reports an RV camper at Honeysuckle Hollow.
Dump station timing: Plan dump station use strategically to avoid wait times during busy checkout periods. "The dump station was near the entrance to the camping loop and had potable water. It was also very busy and we had to wait when filling up and again when dumping," notes Tina from Honeysuckle Hollow Campground.
