Michigan takes a curated approach: metal detecting in state parks is allowed without a permit where the DNR’s official park maps show an area as open, and five parks are fully open. Anywhere else in a state park or recreation area, you need written authorization from the unit supervisor or manager. Here’s how the tiers work and what the rules require.

The rules, land by land
State parks
Designated areasDetecting is allowed without a permit in the areas shown as open on each park's DNR access map: 5 parks are fully open and 52 have mapped areas. Anywhere else in a state park or recreation area needs written authorization from the unit supervisor or manager.
- fully open: Brimley, Grand Haven, Lakeport, Mears and Traverse City state parks
- designated areas per the park's access map (52 parks and recreation areas listed); maps are published by April 15 each year
- Flint State Park: by permit only, through Genesee County Parks
- elsewhere in any state park or recreation area: written authorization of the unit supervisor or manager
- never at designated historic and archaeological sites
- all recovered items must be checked by a unit employee; leave artifacts in place
- probes or small hand trowels only; replace disturbed material
What the rule says
“A person shall not do any of the following in any state park (SP) or recreation area (RA): (1) Use a metal detector outside of a designated area illustrated as open on the access map as published on the department website by April 15th of each calendar year, without written authorization of the unit supervisor or manager.”
Keeping finds
ProhibitedIn Michigan state parks, relics, aboriginal antiquities and abandoned property of historical or recreational value are kept by the state, and staff must check everything you recover.
- all recovered items must be checked by a unit employee
- artifacts must be left in their original position
- items recorded as lost are returned to the owner by park staff when ownership can be established
- the source does not say what happens to modern items that are not historic and not recorded lost
What the rule says
“Any artifacts found shall be left in their original position. Relic or aboriginal antiquities and abandoned property of historical or recreational value will be retained by the state.”
State & public land
No verdict yetNo cited source sets a detector rule for Michigan state land outside state parks and recreation areas, such as state forests and game areas. Part 761 reserves exploring and excavating antiquities to the state (see the dig and keep rules).
Digging
Research permits onlyExploring, surveying and excavating aboriginal records, antiquities and historic abandoned property on Michigan state land is reserved to the state and its authorized officers and agents.
- covers mounds, earthworks, forts, burial and village sites, mines, other relics, and abandoned property of historical or recreational value
- on land owned by or under the control of the state
- in state parks, large-scale digging only as part of a DNR-authorized and permitted archaeological project
What the rule says
“The state reserves to itself the exclusive right and privilege, except as provided in this part, of exploring, surveying, excavating, and regulating through its authorized officers, agents, and employees, all aboriginal records and other antiquities”
Lakes & rivers
Keeping finds
ProhibitedAbandoned property of historical or recreational value found on the state-owned Great Lakes bottomlands belongs to the state; the state's title beats the finder's. Inland lakes and rivers are not covered by this rule.
- state-owned (unpatented) bottomlands of lakes Erie, Huron, Michigan, St. Clair and Superior
- abandoned property includes wrecked aircraft and watercraft, their gear and cargo, and materials from historic and prehistoric Native American activity
What the rule says
“The state reserves to itself a possessory right or title superior to that of a finder to abandoned property of historical or recreational value found on the state owned bottomlands of the Great Lakes.”
Great Lakes beaches
Varies by siteGreat Lakes beaches inside listed state parks are open where the park is fully open or its access map shows the area as open, with no permit. Other beaches are not covered by any fetched source.
- fully open parks include Grand Haven and Mears
- Holland, Muskegon, Warren Dunes, Silver Lake, Tawas Point, Hoffmaster, Saugatuck Dunes and others: mapped areas only
- elsewhere in a state park: written authorization of the unit supervisor or manager
- beaches outside state parks and recreation areas: no cited source
What the rule says
“A person shall not do any of the following in any state park (SP) or recreation area (RA): (1) Use a metal detector outside of a designated area illustrated as open on the access map as published on the department website by April 15th of each calendar year, without written authorization of the unit supervisor or manager.”
Other public land
Varies by siteRegional, county and city park systems set their own detecting rules; the Huron-Clinton Metroparks, for example, allow it in many areas with a free permit from the park office.
- Huron-Clinton Metroparks: free permit from the park office; many, not all, areas; ask each park where detecting is barred
- Flint State Park is run with Genesee County Parks and is open by permit only
- elsewhere: ask the county or city parks department
What the rule says
“Metal detecting is permitted in many, but not all, areas of the Metroparks. A permit is required (no cost) which can be picked up at the park office.”
Even where detecting is allowed, archaeological and historic sites are protected, and you must fill every hole and follow posted rules. Always confirm the current rule with the land manager.
Metal detecting in Michigan state parks
The Michigan Department of Natural Resources (DNR) lists the parks and mapped areas open to detecting under the ‘Land Use Order of the Director Amendment No. 6 of 2023,’ put in place to safeguard archaeological and historical resources. The DNR’s own words: ‘While metal detecting is not allowed at designated historic and archaeological sites, it’s allowed in areas specifically designated as open to metal detecting. Any items found must be reviewed by park staff and may be retained for further investigation.’
The list has three tiers: fully open parks (Brimley, Grand Haven, Lakeport, Mears, and Traverse City state parks); by-permit parks (Flint State Park — contact Genesee County Parks); and a long list of parks with designated areas open per the official park map (Holland, Muskegon, Ludington, Warren Dunes, Silver Lake, Tawas Point, Hoffmaster, Saugatuck Dunes, Porcupine Mountains, Wilderness State Park, and many more). Outside those areas, Order 5.26(1) bars detector use without written authorization of the unit supervisor or manager.
Operational rules apply everywhere it’s allowed: all recovered items must be checked by a park employee; any artifacts must be left in their original position; relics, aboriginal antiquities, and abandoned property of historical value are retained by the state; and you may use only probes or small hand trowels — no large-scale digging — replacing any disturbed material.
Great Lakes beaches and bottomlands
Great Lakes beaches inside listed state parks are open to detecting where the park appears on the DNR list and the map allows it — Grand Haven and Mears are fully open, and popular shoreline parks like Holland, Muskegon, Warren Dunes, Silver Lake, Tawas Point, Hoffmaster, and Saugatuck Dunes have designated areas. Follow each park’s map.
Note that the Great Lakes bottomlands owned by the state are covered by Part 761: the state’s title to abandoned property of historical or recreational value found there beats the finder’s (MCL 324.76102(2)). Don’t detect or dig below the water line without confirming it’s allowed.
Michigan’s antiquities law
The Aboriginal Records and Antiquities Act — Part 761 of Michigan’s Natural Resources and Environmental Protection Act (Act 451 of 1994) — reserves to the state aboriginal antiquities such as mounds, earthworks, forts, burial and village sites, and relics on state land.
Other public land in Michigan
The DNR list and Order 5.26 govern state parks. Municipal and county beaches and parks in Michigan set their own rules, which vary. Check the specific local parks department before detecting.
Don’t forget federal land
Sleeping Bear Dunes National Lakeshore, Isle Royale National Park, and other National Park Service land in Michigan prohibit metal detecting under 36 CFR 2.1. See our national guide for the federal picture.

Frequently Asked Questions
- Can you metal detect in Michigan state parks?
- Yes, where the DNR allows it: five parks (Brimley, Grand Haven, Lakeport, Mears and Traverse City) are fully open, Flint State Park is by permit through Genesee County Parks, and many others have designated areas shown on the park map. Anywhere else in a state park or recreation area needs written authorization from the unit supervisor or manager. Any items you recover must be checked by park staff, and artifacts are retained by the state.
- Can you metal detect on Michigan’s Great Lakes beaches?
- Yes, on Great Lakes beaches inside state parks that are on the DNR’s list and where the park map designates it — Grand Haven and Mears are fully open, for example. Use only hand probes or small trowels and replace any disturbed material. Abandoned property of historical value on the state-owned Great Lakes bottomlands belongs to the state.
- What tools can you use metal detecting in Michigan state parks?
- Only probes or small hand trowels, and only if the land isn’t unduly disturbed — you must replace any disturbed material. Large-scale digging isn’t allowed unless it’s part of a DNR-authorized and permitted archaeological project.
