Do you need a Metal Detecting Permit in New Hampshire?

The state of New Hampshire does not require a permit to metal detect, but permitting is required on certain properties. When you’ve selected your location check the park or city rules for specific guidelines. 

These can occasionally be found on their websites under recreation regulations. Most of the time you will have to reach out to a park supervisor or park staff for specific metal detecting permit requirements and procedures.

Can you metal detect in New Hampshire State Parks and forests?

You are allowed to metal detect in state parks and forests on beaches and within 25 feet of picnic tables and park pavilions. As stated above, if there is a historic site, cemetery, or native American site, you are not allowed to metal detect. 

By all accounts, reaching out to park management to directly ask about metal detecting permission is highly recommended. There are several parks in the state known to be friendly to metal detector use as long as permission is requested ahead of time and holes are properly maintained.

Each park can issue individual rules on Metal Detecting. It’s important to review the park’s website and guidelines for any updates and changes. For specific details on each park check out the official website to get updated contact information.

New Hampshire City Guidelines for metal detecting

Below are the rules and guidelines provided by some of the major cities in New Hampshire. Any direct references to local regulations will be accompanied by a direct link.

Other information without links has been verified through direct outreach to city parks and recreation departments. I’ve personally reached out via email and phone to each municipal parks and recreation team and every person I spoke with was happy to help me get the correct information I needed.

While I hope to provide valuable insights into rules throughout these communities, these rules can change especially if people damage the parks through bad digging practices. It’s always a good idea to reach out to the local parks and recreation department or law enforcement for clarification before detecting on public property.

After direct outreach to the City of Manchester Parks and Recreation Department, they confirmed Metal Detecting is not allowed in city parks and other city properties.

Keene, New Hampshire

Metal detecting is not allowed near city water resources

There are currently no formal regulations for metal detecting on dry city parks in Keene. After speaking with Keene’s Parks and recreation team, they are ok with detectorists using the parks but ask for everyone to reduce soil disturbance and follow leave no trace principles.\

You can find updated contact information for the City of Keene Parks and Recreation department on their city website or by calling 603-357-9829

Portsmouth, New Hampshire

There are no available resources outlining metal detecting rules on the city’s website. All accounts online point to no metal detecting being allowed on Portsmouth-owned property and city parks. This is the only city mentioned in state regulations and without direct permission and coordination with local authorities, you cannot metal detect here.

To contact the City of Portsmouth Parks Department you can find their contact information on their website “Linked Here”

Laconia, New Hampshire

A permit is required to metal detect in Laconia city parks and on city property. Source >

Contact information for the parks and recreation department to inquire about a permit can be found here: Laconia Park and Recreation Directory

Lebanon, New Hampshire

There’s a bit of a catch-22 in Lebanon. While the use of a metal detector is technically allowed in city parks, digging is prohibited. For that reason, you can more or less consider metal detecting banned on city-owned properties and parks in Lebanon.

On Lebanon conservation lands, you are able to use a metal detector and dig as long as there is no historic site present in the area. It’s also requested that use follow strict leave no trace best practices while digging on these properties to prevent firm regulations prohibiting digging on these lands as well.

If you have any questions about metal detecting in Lebanon or if you would like to confirm these rules you can contact Paul Coates at or by calling 603-448-5121.

Best Public Places to metal detect in New Hampshire

Overall, New Hampshire is a fairly restrictive state when it comes to metal detecting. Most cities disallow or discourage the use of metal detectors and so does the state outside of the clearly defined locations outlined above.

When searching for locations you’re limited to one national forest and state lands with beaches or picnic/pavilion areas. Keep in mind most beaches are not owned by the state so cross-reference your locations with the state’s provided map.

White Mountain National Forest

The largest area to metal detect in the state, White Mountain National Forest is a prime area to explore with a detector. Outside of public beaches, this location has the lowest barrier to entry to get started.

While you’re allowed to go metal detecting in national forests, it’s a good habit to still reach out for clarification and written permission. You can contact the forest team through this form. It does clearly state that the inbox isn’t monitored daily so plan ahead if you just want to operate through email. Otherwise, a phone number is also provided for a quick contact option.

While in a national forest you’ll need to follow ARPA rules, here’s a link to review those regulations.

Hampton Beach

Located on the central New Hampshire coast, Hampton Beach is a popular summer destination for locals and tourists alike. The beach stretches for more than three miles and offers a wide variety of activities, including swimming, sunbathing, fishing, and boating.

Visitors can also enjoy the many shops and restaurants that line the Boardwalk, or take a short drive to the nearby Seabrook Nuclear Power Plant. With its beautiful sandy beaches and abundant amenities, Hampton Beach is the perfect place to relax and enjoy the summer sun.

This high foot traffic creates an abundance of lost items. A well-timed trip after a long weekend would help cut down on the crowd while increasing your chances of finding that lost ring.

North Beach

North Beach is a beautiful sandy beach directly adjacent to Hampton Beach. North Beach is open to the public from Memorial Day weekend through Labor Day weekend. During these months, the beach is lifeguarded and there are restrooms and showers available for use. Outside of these months, the beach is still open to the public but there are no lifeguards on duty and the restrooms and showers are closed.

Ellacoya State Park

A beach, picnic tables, and pavilions all provide a good amount of ground that can be covered in the park. The local popularity of the park makes it a good location to visit after holidays and busy weekends.

Pawtuckaway state park

There is a beach and pavilions that fall within the state guidelines for metal detecting on state-owned land. To inquire about metal detecting in other parts of the park reach out to the park’s office for more details and to request written permission.

The website for the Pawtuckaway mentions the beach reaching max capacity early in the morning during popular weekends and holidays. If you’re hoping to hit the beach, I suggest going during a non-holiday weekend or during a weekday to avoid the crowds.
