Moraine Hills State Park Kettle Loop
CCC roads through glacial kettle moraine terrain.
The Kettle Loop at Moraine Hills follows old CCC roads built in the 1930s through some of Illinois’s most dramatic glacial terrain, where retreating ice sheets left behind a landscape of kettle lakes, rolling hills, and oak savannas. The route connects Lake Defiance, Tomahawk Lake, and several smaller kettles via maintenance roads originally constructed to access fire towers and work camps. The most challenging section crosses a seasonal wetland between Tomahawk Lake and the northern prairie restoration area, requiring careful navigation during spring snowmelt.
Moderate difficulty due to seasonal flooding and soft prairie soils that can bog down lighter vehicles. High-clearance 4WD recommended, especially April through June when snowmelt and spring rains turn the prairie sections into mud bogs. Fall colors are spectacular, and winter access is possible when frozen. No overnight camping within the park, but nearby Chain O’Lakes State Park offers developed sites. This route showcases Illinois’s glacial heritage better than most, with interpretive stops explaining the area’s 12,000-year history.

Frequently asked questions
Can a stock Jeep Wrangler or 4Runner handle this trail without modifications?
A stock high-clearance 4WD is the minimum and will get through, but the kettle terrain throws off-camber situations and soft dirt that will push a bone-stock rig. Lockers or at least good all-terrain tires make a real difference here.
What months is the Kettle Loop actually accessible and rideable?
Best window is July through November. Spring thaw turns the glacial soil into a muddy mess and the park service will close trails to prevent damage — check Illinois DNR conditions before you go.
Do I need a permit or is there a fee to run this trail?
Illinois State Park vehicle sticker is required — $30 for Illinois residents, $40 for out-of-state. No additional trail permit needed, but confirm current fee info at illinois.gov/dnr before your trip.
What's the hardest section and what should I actually expect?
The tightest challenge comes from the combination of steep kettle bowl descents and the water crossings on the CCC road segments — nothing technical enough to require a winch, but slick dirt on the moraine slopes will bite you if you're moving too fast or on street tires.
Are there places to camp inside or near the trail, and how far is the nearest gas?
Moraine Hills has designated campgrounds in the state park — reserve through the Illinois DNR reservation system ahead of time, especially on summer weekends. McHenry is your fuel stop, roughly 5 miles from the trailhead, so top off before you head in.
