When cancellations show up
Illinois State Parks (Explore More Illinois) opens its booking window on its own schedule — camp.exploremoreil.com is the source for the exact date. What's constant is what happens after: sites fill, plans change, and cancellations go back onto the calendar. PermitSnag watches campgrounds here and texts or emails you the moment one opens up.
