Forest Preserve District: NOTE CHANGES

How about a cold-weather walk to start off to start off your New Year's resolutions?

It's a great time to take a walk--if you practice social distancing.

Now that the city parks and lakefront are closed, people are turning to the forest preserve sites more than ever. While many of the forest preserves remain open, these, too, will close unless everyone practices social distancing. 

If you witness people congregating or not observing social distancing guidelines, please call the forest preserve non-emergency number: 708-771-1000. 

At nature centers, however, the buildings, grounds, trails, and bathrooms will be closed through May 11. All campgrounds, the Swallow Cliff Stairs, permit offices, bathrooms, and other structures are also closed until that date. All public and permitted events have been cancelled through May 11.

Stay at home if you are sick or experiencing symptoms.
