Maine allows metal detecting in its state parks — but only with a written permit obtained at that specific park, and never at historic sites. The permit is issued park by park. Here’s exactly how it works.

The rules, land by land
State parks
Permit requiredMetal detectors are allowed in state parks only by written permit obtained at the individual park, and are prohibited entirely at historic sites.
- written permit obtained at the park
- prohibited at historic sites
What the rule says
“Use of metal detectors at historic sites is prohibited. Metal detectors are allowed in other areas only by written permit obtained at the park.”
State & public land
No verdict yetNo source read sets a detector rule for Maine state land outside parks; Maine's archaeology law requires a permit to excavate posted protected sites on state-controlled land (see digging).
Digging
Research permits onlyExcavating a protected archaeological site on state-controlled land needs a permit applied for with a research proposal and cosigned by the state's preservation, museum and land-agency directors.
- any person, agency or institution must apply in writing to excavate a protected site (§374(2)(A))
- For state-controlled land, §373-A(7-A)(A) covers posted sites listed in the National Register or judged eligible by MHPC; an eligible-site designation also needs the land manager or local governing body’s approval. Section 378 emergency-designated protected sites are also covered.
- permit cosigned by the MHPC and State Museum directors and the land agency director (§374(2)(C))
- principal investigator normally holds a graduate degree in anthropology, archaeology or a related field (§374(3)(D))
What the rule says
“Application for a permit must be in the form of a letter and research proposal directed to the Director of the Maine Historic Preservation Commission”
Keeping finds
ProhibitedArchaeological objects found on, in or beneath state-controlled land belong to the State, held by the State Museum.
- archaeological objects, materials and specimens
- state-controlled land includes state parks, recreation areas, public lots and land under great ponds; excludes Baxter State Park (§373-A(10))
What the rule says
“The State designates the State Museum to hold title, as trustee for the State, to all archaeological objects, materials and specimens found on, in or beneath state-controlled lands.”
Beaches
Varies by siteState-park beaches (e.g., Popham Beach State Park) need the same written park permit; town and private beaches follow local rules or need landowner permission, and no source for them was read.
- state-park beaches: written permit obtained at the park
- historic sites prohibited
- town, municipal and private beaches: no cited source
What the rule says
“Use of metal detectors at historic sites is prohibited. Metal detectors are allowed in other areas only by written permit obtained at the park.”
City / county parks
No verdict yetNo detecting rule was confirmed for city or county parks in Maine; ask the park manager.
National Park Service land
ProhibitedPossessing or using a metal detector is prohibited in National Park Service areas.
- Exceptions include a device broken down and packed to prevent use, navigation and safety equipment, and equipment used for authorized scientific, mining or administrative activities.
What the rule says
“Possessing or using a mineral or metal detector, magnetometer, side scan sonar, other metal detecting device, or subbottom profiler.”
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 Maine state parks
The Maine Bureau of Parks and Lands (Department of Agriculture, Conservation & Forestry) park rules state, verbatim: “Use of metal detectors at historic sites is prohibited. Metal detectors are allowed in other areas only by written permit obtained at the park.” The permit comes from the specific park office, and where within the park you may detect is at park management’s discretion.
Maine’s antiquities law
Maine Revised Statutes Title 27, Chapter 13 (Archaeology) puts title to archaeological objects found on state-controlled land in the State Museum (§372(2)). Excavating a protected site requires a permit under §374(2). Protected sites include posted state-controlled sites that are National Register listed or judged eligible by MHPC (with land-manager or local-body approval for eligible-site designation); posted, National Register-listed sites under preservation agreements; and sites emergency-designated under §378. The permit is cosigned by the Directors of the Maine Historic Preservation Commission and the State Museum, plus the managing agency on state land.
Beaches, local rules & federal land
State-park beaches such as Popham Beach State Park fall under the same Bureau of Parks and Lands rule — a written permit obtained at the park is required, and any historic-site portions are off-limits. Beaches outside the state-park system (town, municipal, or private) follow local ordinance or require landowner permission. On federal land, Acadia National Park (NPS) prohibits detecting entirely under federal rules. See our national guide.

Frequently Asked Questions
- Can you metal detect in a Maine state park?
- Yes, but only with a written permit obtained at that specific park, and never at historic sites. Whether and where detecting is permitted within the park is at the discretion of park management.
- Do you need a permit to detect on a Maine state-park beach like Popham?
- Yes. State-park beaches are covered by the same Bureau of Parks and Lands rule requiring a written permit obtained at the park, and historic areas remain off-limits. Beaches that are not part of the state-park system follow local town rules or require landowner permission.
- What law protects historical artifacts in Maine?
- Maine Revised Statutes Title 27, Chapter 13 (Archaeology). The Act vests archaeological objects found on state-controlled land in the State Museum. Excavating a protected site normally requires a permit cosigned by the MHPC and State Museum directors and, on state land, the managing agency director. Section 375(1) excepts a demonstrable emergency threatening the site’s survival if a permit is immediately applied for under §374. Protected sites include posted state-controlled sites that are National Register listed or judged eligible by MHPC (with land-manager or local-body approval for eligible-site designation); posted, National Register-listed sites under preservation agreements; and sites emergency-designated under §378. At NPS units, recreational detecting is prohibited, with the possession and authorized-use exceptions in 36 CFR 2.1(a)(7).
