Chain O Lakes State Park is one of the most popular water-oriented recreation destinations in northeastern Illinois. Located in the heart of Illinois’ largest concentration of natural lakes, the park offers a wide range of outdoor activities, including camping, boating, kayaking, fishing, hiking, biking, horseback riding, picnicking, and winter recreation.
The park borders Grass Lake, Marie Lake, and Nippersink Lake, while the Fox River connects seven additional lakes in the Chain O’ Lakes system. Turner Lake, a separate 44-acre lake, is also located inside the park. Together, the broader water system provides nearly 6,500 acres of water and about 488 miles of shoreline.

What Makes Chain O Lakes State Park Special?
The park’s biggest attraction is its interconnected water system.
Chain O Lakes State Park borders three natural lakes:
- Grass Lake
- Marie Lake
- Nippersink Lake
The Fox River connects these lakes with seven additional lakes:
- Bluff Lake
- Fox Lake
- Pistakee Lake
- Channel Lake
- Petite Lake

Turner Lake is a separate 44-acre lake within the park.

Things to Do at Chain O Lakes State Park
There are activities available in every season, although summer is the busiest period for water recreation.
Boating
Boating is one of the primary activities at Chain O Lakes State Park.
There is no charge to launch boats at the park, but boats using the Chain O’ Lakes are subject to a user fee from the Fox Waterway Agency. All watercraft must also follow Illinois boating regulations.
Unlike Turner Lake, the main Chain O’ Lakes waterway does not have a horsepower limitation according to Illinois DNR. Turner Lake permits only electric trolling motors.
If you are bringing your own boat, check current Fox Waterway Agency and Illinois boating requirements before your trip.
Boat Launches
Boat launching is available at the park, and the Oak Point boat launch is located off Route 173 near the Fox River.
The park also has kayak launch access at Oak Point and Turner Lake. Parking for the Turner Lake kayak launch is available at the entrance to the Turner Lake South campground.
One important current update is that the Maple Grove Boat Launch is closed until major renovations are completed, according to the Illinois DNR’s current closure information.
Because launch conditions can change, check the official park closure information before traveling with a boat.
Kayaking and Canoeing
Kayaking is a good option for visitors who prefer quieter recreation on the water.
Kayak launches are available at:
- Oak Point boat launch
- Turner Lake
Turner Lake is particularly different from the main Chain because only electric trolling motors are allowed there.
Paddlers should wear appropriate personal flotation devices and check weather and water conditions before launching.
Fishing
Fishing is another major reason people visit Chain O Lakes State Park.
Common species include:
- Bluegill
- Largemouth bass
- Walleye
- Crappie
- Muskie
- Northern pike
- Bullhead
- Catfish
- Yellow bass
- White bass
The marshy shoreline means fishing from boats or designated piers can be particularly useful. Illinois DNR also identifies fishing from boats or piers as a popular approach at the park.
Before fishing, check current Illinois fishing-license requirements, seasons, size limits, and bag limits.
Hiking
Chain O Lakes State Park has several trail opportunities.
The Nature’s Way Trail begins at Oak Grove Picnic Area and covers approximately 2¼ miles. There is also a quarter-mile accessible trail at Pike Marsh North Picnic Area.
These trails offer opportunities to experience the park’s woodland, marsh, lake, and wildlife habitats without needing a boat.
Biking
The park has four surfaced bike trails totaling approximately six miles:
- Goldfinch Trail
- Badger Trail
- Sunset Trail
- Cattail Trail
The biking and hiking trail system can be accessed from picnic areas between the concession stand and park office.
Cyclists should remember that the park’s trail guidance requires bicyclists to yield to pedestrians and stay on surfaced trails.
Horseback Riding
Chain O Lakes State Park also accommodates horseback riding.
The equestrian trail system has three loops totaling approximately eight miles. Visitors may bring their own horses, and a horse-trailer parking area provides access to the trails near the park entrance.
This is an unusual feature for a lake-focused state park and makes the destination appealing to equestrian visitors as well as campers and boaters.
Picnicking
The park has seven picnic areas:
- Oak Point
- Deer Path
- Hickory Grove
- Pike Marsh
- Oak Grove
- Catfish Cove
- Maple Grove
Several picnic areas provide tables, grills, water, and restroom facilities. Oak Point and Oak Grove also have playground equipment.
Picnic shelters are available for reservation, which can be useful for family gatherings and organized groups.
Archery
Chain O Lakes State Park has an archery range for target practice located on Route 173 west of the Fox River.
Illinois DNR states that the range and associated trails are open from May 1 until the beginning of hunting season, with the closing date varying. Listed hours are 8:30 a.m. to 8 p.m.
Check current seasonal information before planning an archery visit.
Winter Activities
Chain O Lakes State Park changes considerably during winter.
When conditions are suitable, visitors can enjoy:
- Ice fishing
- Ice skating
- Snowshoeing
- Sledding
- Cross-country skiing
Ice fishing is available on both the Chain O’ Lakes and Turner Lake. A sledding hill is located near the park office. When snow is sufficient, cross-country skiers can use the horse, bike, and Nature’s Way trails.
Winter activities should only be attempted when ice and weather conditions are safe.
Chain O Lakes State Park Camping
Camping is one of the park’s biggest attractions.
The park has more than 230 campsites divided among several camping areas, including Class A-Premium and Class B-Premium sites, plus a youth group campground.
Class A-Premium Campgrounds

2026 Chain O Lakes State Park Camping Information
The 2026 camping season has some important updates.
Illinois DNR states that limited campground availability began March 1, 2026, while the full campground opened for reservations on April 1. The campground is scheduled to close for the season on October 18, 2026.
There are also electrical upgrades affecting Fox Den and Honeysuckle Hollow. The DNR currently states that Fox Den will be walk-in until the work is complete, while Honeysuckle Hollow remains available for reservations until construction begins.
Because construction schedules and campsite availability can change, campers should check the latest Illinois DNR campground information before booking.
How to Reserve a Campsite
Reservations are accepted through Illinois’ ExploreMoreIL camping reservation system or by phone.
The park currently lists:
- Campsite reservation fee: $5, nonrefundable
- Youth group reservation fee: $5, plus camping fee
- Shelter reservation: $50, nonrefundable
Reservations can be made through ExploreMoreIL or by calling 866-716-6550. Youth group sites are booked through the park office at 847-587-5512.

Chain O Lakes State Park Camping Rules
Campers should understand the park’s basic rules before arriving.
According to Illinois DNR:
- Camping requires a permit.
- The maximum campsite stay is 14 nights within a 30-day period.
- Alcohol is prohibited in the campground.
- Gathering firewood from the park is prohibited.
- A responsible adult obtaining a camping permit must have a camp shelter and set it up at registration.
- Reservations have nonrefundable fees.
Pets are permitted but must be kept on leashes, and owners are responsible for cleaning up after them.
Always check the latest regulations because individual facilities or seasonal conditions may result in temporary changes.
What Are the Campgrounds Like?
The campground map shows several distinct camping areas spread throughout the park.
Honeysuckle Hollow has electric and non-electric sites, while Fox Den is an electric campground. Turner Lake South, Mud Lake East, and Prairie View are non-electric areas. The park map also identifies shower facilities, fishing piers, boat launches, playgrounds, accessible sites, and other facilities.
If electricity is important for your trip, pay close attention to the individual campground and site information when making a reservation.
Are There Showers and Other Camping Facilities?
Yes. The official campground map identifies shower facilities in campground areas and other supporting facilities such as water hydrants, pit toilets, a sanitary station, playgrounds, fishing piers, and boat-launch access.
Available facilities can vary by campground, so check the current campsite information for the specific area you plan to use.
Chain O Lakes State Park Boat Rentals and Concessions
The park has traditionally offered a concession area with food, ice, drinks, ice cream, fishing equipment, bait, firewood, and camper supplies. Boat and canoe rental services have also been associated with the concession area.
However, the concession operation is changing in 2026.
Illinois DNR currently states that Lily Bug Acres West is expected to operate at the Chain O’ Lakes concession area in 2026. The concession page says the operator hopes to bring back watercraft rentals after completion of boat dock and concession-area upgrades, with the completion date still to be determined.
For that reason, visitors who specifically need a rental boat or canoe should confirm availability before traveling rather than assuming rentals are operating.
Chain O Lakes State Park Map
A map is especially useful when planning a trip because the park contains several campgrounds, picnic areas, boat launches, trails, fishing areas, and roads.
The official campground map identifies areas including:
- Honeysuckle Hollow
- Fox Den
- Turner Lake South
- Mud Lake East
- Prairie View
- Mud Lake West
- Oak Grove
- Deer Path
- Hickory Grove
- Pike Marsh North
- Pike Marsh South
- Catfish Cove

It also identifies boat launches, shower facilities, fishing piers, accessible sites, and other amenities.
For trip planning, use the current official Illinois DNR map because site numbers and facilities can be updated.
Turner Lake Nature Preserve
Turner Lake is more than simply another fishing and paddling location.
Approximately 80 acres within Chain O Lakes State Park have been designated as a nature preserve to protect part of the area’s bog environment and its distinctive plant communities.
This makes the Turner Lake area particularly interesting for visitors interested in plants, birds, wetlands, and natural habitats.
Wildlife and Birdwatching
The park provides habitat for a wide range of wildlife.
Illinois DNR notes that nearly 200 bird species have been identified in the park, and a bird checklist is available at the park office.
The combination of wetlands, lakes, woodland, and shoreline habitat creates opportunities for birdwatching throughout the year.
Visitors should observe wildlife from a respectful distance and avoid feeding or disturbing animals.
Hunting at Chain O Lakes State Park
Hunting is another seasonal activity at the park.
Illinois DNR’s state park information indicates that firearm hunting for deer and waterfowl is offered by lottery, while bowhunting opportunities include deer and turkey.
Because hunting can affect trail and facility access, visitors should check current seasonal closures and regulations before hiking, horseback riding, or planning other activities during hunting seasons.
Chain O Lakes State Park History
Chain O Lakes has a long human and natural history.
The area was inhabited by Central Algonquian leagues when Europeans arrived in the mid-1600s, including the Miami, Mascouten, and Potawatomi. French explorers and traders later traveled through the area, and Joliet and Marquette passed through what is now the park during their 1673 exploration along the Fox River.
The state park was established in 1945 after Illinois acquired an initial 840 acres.
A Civilian Conservation Corps camp from the 1930s later became the Chain O Lakes Conservation Area, and that land was incorporated into the state park in 1957.
The history adds another dimension to the destination beyond its recreational opportunities.

Tips for Visiting Chain O Lakes State Park
Reserve Popular Campsites Early
Chain O Lakes is a premium campground, and summer weekends can be popular. Reserving early gives you a better chance of finding your preferred campground and site.
Check Current Closures
Do not rely on an old map or older travel article. The Maple Grove Boat Launch is currently listed as closed for major renovations, and campground electrical work is affecting some 2026 sites.
Check Boat Requirements
The Chain requires a Fox Waterway Agency user fee for boats, while Turner Lake has its own electric-motor restriction.
Bring Insect Repellent
The park contains extensive wetland and shoreline habitat, so insect protection can be useful, particularly during warmer months.
Start Outdoor Activities Early
Summer weekends can be busy. An early start can make parking, trail use, fishing, and boating more comfortable.
Follow Leave-No-Trace Principles
Do not collect plants, disturb wildlife, litter, or remove natural materials. The park’s trail guidance also prohibits collecting firewood and emphasizes responsible trail use.
Nearby Places to Explore
