Metal Detecting Laws in Maryland
Maryland Park Service generally prohibits relic hunting, artifact removal and metal-detector use without an archaeology permit. The hobby exception is searching for modern coins and jewelry on designated swimming beaches, excluding Point Lookout and Calvert Cliffs, after obtaining permission from the park manager and following seasonal hours.

Local complication
Assateague State Park allows detectors only from the day after Labor Day through May 30 and only ocean-side of the primary dune. Sandy Point publishes separate seasonal hours. Gunpowder Falls identifies the sandy Hammerman swimming beach as its limited area.
Private property
Obtain written owner permission covering the exact boundary, tools, restoration and division of valuable finds. The owner cannot waive laws protecting burials, human remains, archaeological resources, utilities or environmental features.
Federal and tribal land
National parks, forests, refuges, Corps projects, BLM parcels, military installations and tribal lands use separate authorities. Identify the parcel before interpreting a state rule.
Do not confuse access with detecting permission
| Location | Required check | Common mistake |
|---|---|---|
| Maryland state park or managed site | Read the current rule and obtain any site permit or manager approval. | Assuming an entrance pass authorizes detecting and digging. |
| Beach or reservoir | Confirm the sand zone, season, hours, water boundary and recovery tools. | Extending a narrow beach exception into dunes, uplands or adjacent federal land. |
| Wildlife or conservation land | Use that division’s rules rather than the state-park rule. | Assuming all state-owned land follows one policy. |
| Federal land | Identify NPS, USFS, BLM, refuge or Corps jurisdiction and local orders. | Treating public access as permission to remove objects. |
| Private land | Get written owner consent and a finds agreement. | Ignoring protected burials, archaeology or utility hazards. |
Four checks before you unpack the detector
1. Confirm the parcel
Save the agency map or parcel record. Shorelines and reservoirs often contain several managers within walking distance.
2. Separate four permissions
Ask separately about possessing the detector, operating it, excavating or scooping, and keeping the object.
3. Record the conditions
Keep the permit, email or name of the official, together with dates, hours, boundary, depth and tool restrictions.
4. Stop at protected context
Do not disturb burials, artifact clusters, foundations, battlefields, shipwreck material, ordnance or culturally sensitive features.

Leave the site better than you found it
Where detecting is authorized, use only the approved recovery tool and the smallest practical opening. Replace plugs, remove sharp trash, stay out of planted and restored areas, and do not interfere with visitors or facility operations. A signal is not proof that an object may be kept.
If the target may be human remains, ordnance, a burial object, an archaeological deposit or a component of a historic structure, stop. Do not clean or reposition it. Back away, record the location safely and notify the manager or law enforcement as appropriate.
Metal Detecting Laws in Maryland FAQ
Where may hobbyists detect in Maryland state parks?
On designated swimming beaches for modern losses, with park-manager permission and subject to the policy’s exceptions and hours.
Which parks are excluded from the beach exception?
Point Lookout and Calvert Cliffs are expressly excluded by the statewide policy.
When may I detect at Assateague State Park?
From the day after Labor Day through May 30, ocean-side of the primary dune.
What are Sandy Point summer hours?
Its beach page says 7 a.m. to 9 a.m. from the Saturday before Memorial Day through Labor Day.
Can I hunt for relics under the beach exception?
No. The exception is for modern coins, jewelry and similar recent losses.
Can I detect in Maryland wildlife management areas?
Not without the required Office of Archaeology permit; WMA pages prohibit unauthorized use.
Does manager permission replace the archaeology permit?
Only for the narrow modern-loss swimming-beach exception. Relic research follows the archaeology permit process.
Can I search adjacent water?
Check the specific park policy and controlled-water boundary; do not assume beach permission extends offshore.
Compare a permission-ready detecting kit
After the manager confirms the location and recovery method, compare current detectors, pinpointers and low-impact tools.
