Illinois deer zones
Illinois does not have a deer season. It has 2 of them, and the boundaries between them were drawn by Illinois Department of Natural Resources along highways, rivers and county fragments rather than anything you can see from a stand. In several states those boundaries are not even the same from one weapon season to the next.
This page publishes the agency’s zone names and links the agency’s own zone map, which is where a hunter’s zone is determined. A wrong zone answer is a wrong season date.
