Metal-detecting answer
Metal detecting is limited to the red-shaded areas on DNR’s currently linked Algonac map. Only registered campers may metal detect in campground areas. All other areas are closed unless the unit supervisor or manager gives written authorization.
Where you can detect
All recovered items must be checked by a unit employee. Artifacts must be left in their original position; relics, aboriginal antiquities, and abandoned property of historical or recreational value are retained by the state. Recorded lost property may be returned to its owner by park staff.
Before you go
Use the current DNR-linked map, detect in campground areas only if you are a registered camper, and contact Algonac State Park at 810-765-5605 if a boundary or authorization question is unclear.
Check posted signs before you go. Rules, closures, maps, and permit procedures can change.
