Is Metal Detecting Legal in Pennsylvania?

Pennsylvania is one of the most detector-friendly states for state parks. Many state parks allow metal detecting from sunrise to sunset with no fee and no permit, with limits on digging tools and on swim beaches during summer.

Pennsylvania state parks: Pennsylvania DCNR allows metal detecting in many state parks from sunrise to sunset at no charge. Swimming beaches are open to detectors only in the off-season, from the Tuesday after Labor Day to the Saturday before Memorial Day. Shovels and trowels are not allowed in turf; only narrow probes may be used. Historic and archaeological areas are closed, so check the individual park's rules before you go.

Other state land in Pennsylvania: State forest and state game land rules are set separately from state parks. Pennsylvania Game Commission land in particular has its own restrictions. Confirm with the managing agency before detecting outside a state park.

Pennsylvania's artifact law: The Pennsylvania History Code (Title 37, Pennsylvania Consolidated Statutes) protects archaeological sites on land owned by the Commonwealth. Excavating them requires authorization from the Pennsylvania Historical and Museum Commission.

Where you can legally metal detect in Pennsylvania: State parks that allow detecting are the standout option. Private farmland with written permission is also common and productive in the colonial and Civil War regions. Municipal parks vary, so ask the borough or township.

Pennsylvania-specific traps to avoid: Gettysburg National Military Park and Valley Forge National Historical Park are NPS units where detectors are banned. Detecting on these sites is prosecuted. The Dent's Run Confederate-gold legend in Elk County centers on state forest land where the FBI excavated in 2018. Digging there is not open to the public.

For archaeologists and researchers in Pennsylvania: Archaeological work on Commonwealth-owned land must be authorized by the Pennsylvania Historical and Museum Commission, which also serves as the State Historic Preservation Office. Recorded sites and surveys are held in PA-SHARE, the state's online historic resources system, where professional access is available on request.

Can I metal detect in Pennsylvania state parks? Yes, in many of them, sunrise to sunset with no fee. Swim beaches are open only in the off-season, and only narrow probes may be used in turf.

Can I metal detect at Gettysburg? No. Gettysburg National Military Park is a National Park Service unit where metal detectors are prohibited.

Federal land in every state: National Park Service units ban metal detectors (36 C.F.R. § 2.1), and the Archaeological Resources Protection Act protects archaeological resources 100 years or older on federal and tribal land. Professional excavation or removal on federal land requires an ARPA permit from the managing agency (43 C.F.R. Part 7). See our national overview for details.
