How Illinois State Park Permits Work for Metal Detecting Near O’Fallon
If you want to metal detect at an Illinois state park near O’Fallon, you’ll need to obtain a permit directly from the park office, where staff will issue one valid for either six months or one year.
Once permitted, you’re restricted to hand-carried devices and small tools like knives, ice-picks, or screwdrivers — shovels, picks, and entrenching tools are strictly prohibited.
You must also restore any disturbed ground to its original condition and stay within the areas your site superintendent has designated.
Obtaining Your State Permit
Securing a state permit is your first step before metal detecting in any Illinois state park near O’Fallon.
Visit the park office directly to complete your permit application — no online option exists.
