Metal detecting laws in New Hampshire are spelled out in detail under New Hampshire Administrative Rules Res 7301.19.
The rule is specific and reasonably permissive: metal detectors are allowed along the shoreline of state park beaches, at athletic fields, playgrounds, and within 25 feet of picnic tables and pavilions, unless otherwise posted.
State historic sites, including Odiorne Point State Park, are off-limits. Digging on sand beaches is allowed to a maximum depth of 12 inches with all holes completely filled.
This is one of the clearest state park detecting rules in New England. Unlike Massachusetts (supervisor-by-supervisor permission) or Maine (written permit from park office), New Hampshire has a straightforward regulation that tells you exactly where you can and cannot detect.

Metal Detecting Laws and Regulations in New Hampshire
Metal detecting laws in New Hampshire are codified in NH Administrative Rules Res 7301.19. Here is the breakdown.
State Parks (Res 7301.19)
The regulation is specific: metal detectors shall be permitted along the shoreline of state park beaches and at athletic fields, playgrounds, and within 25 feet of picnic tables and pavilions, unless otherwise posted. No person shall use metal detectors at state historic sites, including Odiorne Point State Park.
Money or items found whose value is in excess of $5.00 shall be reported to the park manager or regional supervisor.
Digging Rules (Res 7301.20)
Digging is permitted on sand beaches with all resulting holes completely filled in. Digging to a depth greater than 12 inches is not permitted. Digging and other ground disturbances are not permitted at state parks and historic sites except as permitted by the DRED director with concurrence of the Department of Cultural Resources, Division of Historical Resources.
This means you can dig on sand beaches (up to 12 inches, fill all holes) but cannot dig in non-beach areas (athletic fields, playgrounds, near picnic tables) without special approval. In those non-beach permitted areas, you can scan and recover surface items but should not dig into the turf.
State Historic Sites (Prohibited)
All state historic sites are off-limits. This includes Odiorne Point State Park (specifically named in the rule), Fort Stark, Fort Constitution, and all other DRED-owned historic properties listed on the state’s property inventory. Cemeteries and Native American burial grounds are also off-limits.
White Mountain National Forest
The White Mountain National Forest covers over 750,000 acres in New Hampshire (and a small portion in Maine). It is the largest area of public land in New Hampshire. General Forest Service policy allows recreational detecting in developed areas (campgrounds, recreation sites). ARPA artifact restrictions apply. Contact the Forest Supervisor for current policy.
City and Town Parks
No New Hampshire cities or counties are currently listed as requiring metal detecting permits or prohibiting the activity. However, individual towns may have rules. Lebanon prohibits detecting in city parks but allows it on conservation lands with leave-no-trace practices. Hampton Beach (a state beach managed by DRED) allows detecting under the state park rule. Most towns have no specific regulation.
Contact the specific town before detecting if you are unsure.
Private Land
Private land with written landowner permission is excellent for relic hunting. ARPA does not apply. New Hampshire’s colonial history dates to 1623 (Portsmouth and Dover), and old homesteads, tavern sites, and colonial settlements on private land produce outstanding finds.
Rules Summary
| Land Type | Detecting Allowed? | Digging Allowed? | Found Items |
|---|---|---|---|
| State Park Beaches | Yes (shoreline) | Sand only; max 12″; fill all holes | $5+ reported to park manager |
| State Park Fields/Playgrounds/Picnic Areas | Yes (within designated zones) | No (surface recovery only) | $5+ reported |
| State Historic Sites | No (including Odiorne Point) | No | N/A |
| White Mountain National Forest | Developed areas | Hand tools; casual use | ARPA restrictions |
| Town Parks | Generally yes (check locally) | Varies | Varies |

Best Metal Detecting Locations in New Hampshire
New Hampshire’s coastline, state parks, and colonial history offer diverse options.
- Hampton Beach State Park (Rockingham County) – New Hampshire’s most popular beach. Heavy tourist traffic produces excellent modern finds. Detecting allowed on the shoreline under Res 7301.19. Dig up to 12 inches in sand. Summer weekends are most productive for lost jewelry.
- Wallis Sands State Beach (Rockingham County) – A state beach in Rye. Detecting allowed on the shoreline. Smaller and less crowded than Hampton, but still productive.
- White Mountain National Forest (various counties) – Over 750,000 acres with developed campgrounds and recreation areas. With Forest Supervisor permission, these areas may allow detecting. The forest area has logging-era, resort-era, and frontier history.
- Lake Winnipesaukee area parks (Belknap, Carroll Counties) – New Hampshire’s largest lake with resort history dating to the 1800s. State park beaches on the lake allow detecting. Weirs Beach and other popular swimming areas produce modern finds from decades of tourism.
- Seacoast area private land (Rockingham County) – Portsmouth (1623), Dover (1623), and Exeter (1638) are among the oldest English settlements in America. Private land near these colonial communities produces some of the earliest colonial artifacts in the country.
- Connecticut River Valley private land (various western counties) – The Connecticut River towns have deep colonial history. Private farmland near old settlements, tavern sites, and stage stops produces coins and artifacts from the 1700s onward.
- State park athletic fields and playgrounds (various parks) – Under Res 7301.19, these areas are open for detecting. Older state parks established decades ago accumulate coins and jewelry from visitor use. Surface recovery in these non-beach areas.
- Old mill town sites (various counties) – New Hampshire’s mill towns (Manchester, Nashua, Dover) have industrial history from the early 1800s. Private land near old mill worker neighborhoods produces industrial-era coins and personal items.

New Hampshire’s History and What You Might Find
New Hampshire was among the first areas of English settlement in America. Portsmouth and Dover were both established in 1623, making them contemporaries of Plymouth Colony. The state played a role in the Revolutionary War (the first overt act of war is sometimes attributed to the raid on Fort William and Mary in New Castle in December 1774, months before Lexington and Concord).
The state’s economy evolved through fishing, shipbuilding, farming, and then the industrial revolution. Manchester became a major textile mill center. The White Mountains attracted resort tourism from the mid-1800s onward, with grand hotels serving wealthy visitors.
Common detecting finds include colonial-era coins (King George coppers), early American coins, Revolutionary War-era buttons and buckles, maritime items along the coast, mill-era coins and personal items, and modern jewelry at beaches and tourist areas. The seacoast area has the deepest history. The White Mountain resort era left coins and personal items at old hotel and campground sites.
New Hampshire has minor gold occurrences in the western mountains but is not a significant gold prospecting state.
Tips for Metal Detecting in New Hampshire
- Know Res 7301.19 exactly. The rule specifies beaches, athletic fields, playgrounds, and 25 feet from picnic tables/pavilions. Stay within these zones in state parks. Non-beach areas are surface-recovery only (no digging).
- Fill all beach holes completely. The 12-inch depth limit and hole-filling requirement are explicit. Compliance protects the rule for all detectorists.
- Report items over $5. The reporting threshold is low ($5). Jewelry, silver coins, and other valuable items found in state parks must be reported to the park manager. Compliance is both legally required and good practice.
- Avoid all historic sites. Odiorne Point State Park is specifically named as off-limits. All other state historic sites, cemeteries, and Native American sites are prohibited. Know the list before detecting.
- Explore the White Mountain National Forest. The 750,000-acre forest is the largest public land detecting opportunity in the state. Old logging camps, resort sites, and CCC-era campgrounds in the forest have detecting potential.
- Target seacoast private land for colonial finds. Portsmouth, Dover, and Exeter have 400 years of English colonial history. Private land with owner permission near these communities produces the oldest and most valuable finds in the state.
- Detect beaches after nor’easters. New Hampshire’s short coastline takes powerful storm hits. Post-storm beach detecting can expose items buried deep in the sand.
- Join a local club. New Hampshire has an active detecting community. Club members share knowledge about productive locations, town rules, and historical research resources.

Conclusion
Metal detecting laws in New Hampshire are among the clearest in New England. Res 7301.19 tells you exactly where you can detect in state parks (beaches, fields, playgrounds, near picnic areas) and where you cannot (historic sites). The 12-inch digging limit on sand beaches and $5 reporting threshold are straightforward rules that protect the hobby’s access.
New Hampshire’s 18-mile coastline is short but productive, and the state’s colonial history (1623) makes private land detecting exceptional. The White Mountain National Forest adds a large block of federal land with casual detecting potential. Follow the rules, explore the beaches and forests, and build landowner relationships for the best colonial-era finds.
