Camping areas near Lake Forest sit within the northeastern Illinois prairie system, where glacial moraines create subtle elevation changes amid wetland ecosystems. Most campgrounds operate from April through October, with summer temperatures averaging 75-85°F and high humidity. Weekend sites throughout the region typically fill 2-3 weeks in advance during peak summer months.
What to do
Kayaking through connected waterways: At Chain O' Lakes State Park, visitors access seven interconnected lakes via tributaries. "We chose Chain O Lakes because we enjoy kayaking and with 7 lakes connected by small tributaries this fit the bill," shares Aida K., who adds that "Rangers were helpful and delivered firewood to our site daily."
Horseback riding: The trail systems offer equestrian options for riders of all experience levels. "There is horse riding here as well. The views are breathtaking," notes Christian V. from Mud Lake East camping area. Rentals are available seasonally, and some campers bring their own horses to designated equestrian-friendly areas.
Biking on varied terrain: Multiple campgrounds feature paved and unpaved cycling routes. Dakota from Prairie View camping area explains their experience: "We did a 5 mile hike through the park. It was absolutely beautiful. Lots of hills, forested areas, open prairies, and multiple water locations including next to the Fox River."
What campers like
Clean facilities despite heavy use: Camp Reinberg maintains particularly high standards. "The shower facilities were clean and the staff very friendly," writes Laura Z., while another camper notes it has "seriously the cleanest [restrooms] I've ever seen, even the ceilings were cleaned!"
Wildlife viewing opportunities: The wetland ecosystem supports diverse animal populations. At Fox Den Campground, Art S. reports: "We did not pass anyone when we went hiking on it. We did have to work our way through a few downed trees. The trail looks like it would be pretty muddy if it rains so choose your timing."
Convenience to Chicago: Fish Lake Beach Camping Resort offers an accessible getaway. "We stayed for 4 nights in June in a pull thru FHU. The mosquitos were pretty vicious... a couple of the regulars said it was the worst they'd been in years. We biked around the campground during the days and took advantage of the adult only hot tub hours at night. It was a nice getaway from Chicago," shares Jenifer K.
What you should know
Alcohol restrictions: Most state parks enforce strict alcohol policies. Kelly G. warns about Mud Lake East: "No alcohol, they will issue a ticket." Private campgrounds typically allow alcohol, but state facilities have consistent enforcement.
Insect preparation is essential: Ticks and mosquitoes pose significant challenges, particularly in summer months. Meg from Turner Lake South cautions: "SO many ticks. With a baby crawling that needed to be set free, we were constantly doing checks... they literally fall out of the trees into people!"
Early gate closures: Many facilities lock entrance gates at night. Grace H. notes: "The park gates close early as well - we returned one evening at 10:30pm and couldn't get back in with a vehicle. Had to go back in on foot. Good to plan ahead!"
Tips for camping with families
Reserve lakefront sites early: The most desirable water-adjacent spots book quickly. Chloe N. recommends certain areas at Fish Lake Beach: "I recommend the lakefront tent sites, they are spacious and you can fish right from your site! The lake is beautiful and surprisingly picturesque as it is all nature preserve on the opposite side."
Wildlife management strategies: Honeysuckle Hollow Camping Area requires special precautions. "The raccoons at night here are no joke. The second it's dusky, they come scavenging for absolutely anything food has touched. So basically, eat dinner and do s'mores early, then everything must be packed into cars for the night," advises Meg.
Playground proximity: Sites near recreational facilities benefit families with young children. Meg also recommended: "We chose the loop 11 was on because it was close to the path to the playgrounds and lakes plus bathrooms… avoid the first 2 sites from either end as the ones closest to the main loop aren't very deep."
Tips from RVers
Limited hookup access: Water connections aren't always available at RV sites. The School for Y. noted at Camp Reinberg: "There are no water spigots at the RV sites. The staff has to hook up a very very long hose and will bring it to your site. You can get water, it's just an inconvenience for you and them."
Specific site recommendations: Paul Wolff Campground offers varied experiences. Marisa A. advises: "The most shaded sites are p1,3,5,7 and 9. Many of the sites in the middle are wide open with little shade but nice summer breezes."
Dump station congestion: Plan for potential wait times when entering or leaving. Tina from Honeysuckle Hollow shares: "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."
