Illinois welcomes detectorists to many state parks — but with a permit, hand tools only, and a Superintendent-designated area. It also has strict archaeology laws and a Chicago-area jurisdiction maze worth understanding. Here’s the detail.

Metal detecting in Illinois state parks
The Illinois Department of Natural Resources (IDNR) requires a Metal Detecting Permit for detecting on IDNR-owned, -managed, or -leased sites, and about 34 state parks offer it. The permit rules limit you to hand-carried devices plus small pen knives, ice picks, or screwdrivers — no shovels or picks — require you to return the area to its original state, and confine detecting to a Superintendent-designated area. On designated beaches, detecting is allowed sunrise to 10 a.m. only. No detecting is allowed on any State Historical, Archaeological, or Nature Preserve site, and items of antiquity must be turned in.
Illinois’s antiquities law
The Archaeological and Paleontological Resources Protection Act (20 ILCS 3435) reserves to the state the exclusive right to excavate archaeological and paleontological resources on public land; disturbing or collecting them without an IDNR permit is a Class A misdemeanor for a first offense, escalating to a Class 4 felony. The Human Remains Protection Act (20 ILCS 3440) protects unregistered graves, mounds, and markers over 100 years old.
Beaches, local rules & jurisdiction
IDNR designated beaches allow detecting sunrise to 10 a.m. in the Superintendent-designated area. In the Chicago area, jurisdiction matters enormously: Cook County Forest Preserves prohibit detecting district-wide, while Chicago Park District (city) beaches have no confirmed published rule — contact the Chicago Park District directly. Some local conservation districts (e.g., Boone County) issue their own permits. See our national guide.
