Trail Rules & Etiquette
- Useofficial, marked trails. Bicycle and horse riders are prohibited from riding off-trail or on unofficial trails. Off-trail and unofficial trail use—even by walkers and runners—damages plant and wildlife habitats.
- Stay to the right. Ride or walk on the right side of the trail and stay single file whenever possible.
- Pass safely. Give an audible warning (examples: ring a bike bell or say “on your left”) and slow down before passing others. Pass in single file only. Ask permission to pass equestrians.
- Yield to other trail users. Bicycle riders must yield to other types of trail users. Walkers and runners must yield to equestrians.
- Keep your dog on-leash. Most trails allow dogs, but they must be on a leash, controlled by their owner and on the right side of the trail.
- Make sure your ride is allowed. Check our web map to see where you can ride a horse or bike (including class 1 and 2 e-bikes). Not allowed anywhere: Class 3 e-bikes; electrically powered scooters, unicycles and hoverboards; and gas-powered vehicles such as ATVs or motorcycles. People with mobility limitations are allowed to use personal mobility devices.
- Travel at a safe speed. Bicycle and e-bike riders must travel at speeds under 15 miles per hour—or slower in busy areas or where a speed limit is posted.
- Pay attention to trail signs. Signs tell you which trail users are allowed and alert you to hazards or busy areas ahead.
- Keep the trail clear. Do not block trails—move to the side of the trail before stopping.
- Stay out of the mud. Avoid using wet trails—if you are leaving prints, you are damaging the trail.

What are your hours?
Forest preserves are open every day from sunrise to sunset. Check with nature centers, campgrounds and other facilities for specific hours. Check for closures before you go.
Do you have bathrooms?
Bathroom availability and type varies by location. Indoor facilities like nature Centers and campgrounds have year-round, accessible indoor bathrooms. Some forest preserves have comfort stations (indoor bathrooms open April through October). Others have portable bathrooms that may be open year-round or seasonally. Some forest preserves do not have bathrooms at all.
Check the specific location you wish to visit for information about bathrooms (including accessibility information).
Why isn’t the gate open at this location?
Forest preserves are open every day from sunrise to sunset and our policy is to open every gate, every day of the year. However, each gate must be opened manually by a Forest Preserves employee every morning—over 300 gates a day. On some days, gates may not be opened by sunrise because of traffic or other issues beyond our control.
Some locations may close temporarily because of weather conditions (snow, ice, flooding), land management (research, restoration, prescribed burns), construction projects or temporary public safety issues.
During winter, parking lots are closed more often because of snow and ice. Parking lots are plowed (with priority given to nature centers, campgrounds and locations with winter activities) and gates are opened as soon as it is safe to allow vehicle access.
Current Closures
Current closures for individual locations are listed on individual location pages and trail pages on this website and on our web map. For a full list of closures, visit our closures page.
How much does it cost to visit?
There is no fee to enter forest preserves or nature centers. Most of our events and programs are free, or charge a small fee.
Other facilities charge fees for usage, including: Aquatic centers campgrounds, golf courses and picnic groves. For a full list of activities that require a fee or permit, visit our Permits Page.
Can I forage for mushrooms, wildflowers or edible plants?
No. The collection of mushrooms, plants, animals or any natural or cultural item is prohibited. With over 5 million residents in Cook County and an estimated 62 million visits to the Forest Preserves each year, allowing foraging or collecting—even through a permitting system—would not be ecologically or financially feasible. Please help us preserve these natural areas for the plants and animals that depend on them, and for future generations to enjoy.
Anyone caught foraging or collecting in the Forest Preserves is subject to a fine of $75 to $500 per offense.
If you see someone foraging in the Forest Preserves, please call our police department at 708-771-1000.
I found a sick, injured or abandoned animal, what should I do?
It depends, but most often the best answer is: Nothing. Learn more about your options on our Wildlife in Distress page.
How can I help the turtle I found?
Turtles are especially visible in spring. Males are more active, seeking mates and moving between ponds. Females are looking for nesting sites to lay eggs. This means you may encounter turtles along roadsides, in yards or crossing paths and streets.
As with all wildlife the best thing to do is to leave them alone—they may appear lost, but they usually know exactly what they are doing. Turtles have an uncanny sense of direction. If moved, they will try and try again to return to their original course. Turtles moved off a pathway will turn around and cross it again if put on the wrong side.
At times, turtles lay eggs in unusual locations like wood chip piles, in a freshly tilled garden bed, or even in a lawn. Even though it is tempting to help out and move them to a new location, those eggs rarely survive. It is best to leave them in place whenever possible. In a worst case scenario, those eggs can become needed food for other animals in the area.
As a rule, the Forest Preserves does not take in injured turtles or eggs and does not deploy staff to relocate turtles or nests. If you believe you have found an injured turtle, learn more about your options on our Wildlife in Distress page.
Can I release my pet or a nuisance animal in the Forest Preserves? Will a nature center take my pet?
Both state and county law prohibit residents from abandoning pets or releasing nuisance animals outside.
The Forest Preserves does not accept pets or wildlife at any of our locations. Learn more about the problems abandoned pets can cause in the Forest Preserves.
If you encounter challenges with your pet and are uncertain about the best course of action, contact a local shelter for valuable resources, guidance on responsible pet ownership and alternative solutions for situations requiring shelter assistance. For a comprehensive list of animal shelters in your region, visit the Animal Shelters Page on the Illinois Comptroller’s Office website or the Lost and Found Pets Page on the Cook County website.
To learn more about preventing problems with wildlife or removing a nuisance animal, visit the Wildlife Illinois website.
Why are trees being cut down?
Trees may be cut down for a variety of reasons:
- Ecological restoration – The Forest Preserves, contractors or partners may remove trees as part of an ecological restoration project. Additionally, volunteers may remove trees at Ecological Stewardship Sites. Most often these are invasive trees, or native trees that have reached unnatural densities due to years of fire suppression. Learn more about restoration and view a list of current restoration projects.
- Utility & highway department tree trimming and removal – Utilities and highway departments regularly monitor and trim or remove trees along roadsides or utility lines for safety reasons.
- Dead tree removal – Dead trees are essential to the health of our local ecosystems. But there are some dead trees that need to be removed because they may create an unsafe situation. Our Resource Management staff regularly removes dead trees from near buildings, roads, parking lots and trails. They have been especially active removing trees affected by the emerald ash borer. If you see a dead tree that you think poses a safety risk, please fill out our contact form (and select “Issues with Trees or Vegetation”) to let us know where to find it.
I have a question about coyotes.
And we have an answer! The Forest Preserves is part of the Urban Coyote Research Project—a partnership between the Forest Preserves, Cook County Animal & Rabies Control, Max McGraw Wildlife Foundation and The Ohio State University started in 2000.
Why don’t you clean up the dead trees in the forest?
While dead trees may not be the most attractive part of a forest, they are essential to its health. Learn more about the important role dead trees play in the Forest Preserves.

Can I collect firewood?
No. The collection of firewood, or any natural or cultural item, is prohibited. Dead trees and resulting fallen wood provide habitat for many plants and animals that call the Forest Preserves home.
Anyone caught collecting in the Forest Preserves is subject to a fine of $75 to $500 per offense.
Can I feed deer, ducks or other wildlife?
No. It’s important to know that feeding wildlife causes more harm than good—learn why feeding wildlife is harmful.
Anyone caught feeding wildlife in the Forest Preserves is subject to a fine of $75 per offense.
If you see someone feeding wildlife in the Forest Preserves, please call our police department at 708-771-1000.
Should I be concerned about ticks and mosquitoes?
Ticks and mosquitoes are a natural part of the Forest Preserves and taking basic precautions can help minimize any potential harm they may cause. Learn how to protect yourself on these pages:
- Ticks & Disease
- Mosquitoes & West Nile Virus
Can I ride an electric bike, scooter or hoverboard?
Class 1 and class 2 e-bikes, operated at speeds under 15 miles per hour, are allowed on all trails where bicycles are allowed, except single track mountain biking trails. Please use only official, marked trails. All bicycle riders are prohibited from riding off-trail or on unofficial trails.
All other motorized vehicles are not allowed on trails, mowed areas and natural areas. Prohibited vehicles include, but are not limited, to: Class 3 e-bikes; electrically powered scooters, unicycles and hoverboards; and gas-powered vehicles such as ATVs or motorcycles. People with mobility limitations are allowed to use personal mobility devices.
Can I use a metal detector?
No. Metal detecting is prohibited. Even practiced responsibly, metal detecting disrupts soils and negatively impacts plants and animals.
Anyone caught metal detecting in the Forest Preserves is subject to a fine of $75 to $500 per offense.
If you see someone using a metal detector or digging in the Forest Preserves, please call our police department at 708-771-1000.
Can I practice archery?
No. Launching any projectile in the Forest Preserves is prohibited. This includes model rockets and all firearms—even Airsoft guns, BB guns or pellet guns.
The Forest Preserves hosts archery events throughout the year. There are currently no plans to construct a permanent archery range on Forest Preserves’ property.
Can I fly my drone?
Yes, but only at the approved locations listed on the Model Airplanes & Drones Page.
Can I swim in lakes and ponds?
No. Because of public health and safety concerns, entering or swimming in any waterbody in the Forest Preserves is prohibited. You are welcome to explore designated waterbodies in an approved boat.
Anyone caught entering or swimming in a waterbody in the Forest Preserves is subject to a fine of $75 to $500 per offense.
Can I use a stand up paddle board (SUP)?
No. Stand up paddle boards (SUP) are prohibited due to public health and safety concerns. The Forest Preserves conducted an SUP feasibility study and the results indicated that the water quality in Forest Preserves waterbodies—which are all human-made—was not high enough for activities that involve a high likelihood of entering the water.
Anyone caught entering or swimming in a waterbody in the Forest Preserves is subject to a fine of $75 to $500 per offense.
Do you plow and salt trails in the winter?
No, we leave our trails in natural winter conditions for cross-country skiing, snowshoeing, winter hiking and other seasonal activities.
Plowing and salting can introduce saltwater runoff into our natural areas and hurt native plants and animals. Additionally, plowing equipment and salt damage trail surfaces, leading to costly and disruptive repairs in the spring and summer seasons.
With these negative impacts and the resources that would be needed to attempt to clear over 350 miles of trails across 70,000 acres, we do not believe plowing and salting trails is compatible with our mission.
All trail use involves risk. Please review our Trail Risk Statement.
What if I find an artifact in the Forest Preserves?
Artifacts are the things that past peoples made, changed, and left behind in places where they lived and worked. Commonly found artifacts include arrowheads, ceramics and historic bottles. Artifacts are not souvenirs and taking them from public lands is illegal. Learn more about what to do on our What If I Find an Artifact in the Forest Preserves? Page.
How do I pay for a ticket?
Tickets issued by Forest Preserves Police Officers in Cook County are to be settled via the Department of Administrative Hearings.
How do I submit a claim?
The Legal Department works to investigate and resolve claims filed by citizens who allege they have been harmed by some act or omission by the Forest Preserves. Visit our Legal page for guidance on filing claims against the Forest Preserves.
