Is Metal Detecting Legal in California?

California has no single statewide state-park rule. Each park unit decides for itself, and many historic units ban detectors outright. Most legal detecting in California happens on public beaches that allow it, on BLM desert land, and on private property with permission.

California state parks: Under 14 CCR § 4326, each California State Parks unit posts its own order allowing or banning metal detectors. Historic units such as Marshall Gold Discovery State Historic Park, along with Lake Oroville and Auburn State Recreation Areas, have posted orders banning detectors to protect cultural resources. Even where detecting is allowed, digging into archaeological features is prohibited. Check the specific unit's page or call the park before you go.

Other state land in California: State-owned lands outside the park system are managed by different agencies with different rules. Treat any state land as closed to digging unless the managing agency confirms otherwise in writing.

California's artifact law: California Public Resources Code § 5097.5 makes it a misdemeanor to knowingly dig up, remove, or damage any archaeological or historic feature on public land without permission from the agency that manages it.

Where you can legally metal detect in California: BLM manages about 15 million acres in California, much of it Mojave and Colorado Desert land where casual recreational detecting is generally allowed outside archaeological sites and wilderness restrictions. Many city and county beaches allow detecting in the sand. Private land works with written permission. Gold-country detecting is common in the Sierra foothills, but much of that ground is claimed or private.

California-specific traps to avoid: Death Valley, Joshua Tree, and Yosemite National Parks, along with Mojave National Preserve, are National Park Service units, where possessing a detector in the backcountry is prohibited. Old hydraulic mining areas in the Sierra foothills can contain mercury. Native American burial sites are protected by Health and Safety Code § 7050.5 and by federal law, and disturbing remains is a serious crime.

For archaeologists and researchers in California: California has no single statewide archaeology permit. Work on state land needs authorization from the agency that manages it, for example California State Parks for park units. Work on BLM or national forest land requires a federal ARPA permit. Recorded site data is held by the California Historical Resources Information System (CHRIS), through regional Information Centers, with access limited to qualified researchers. The Office of Historic Preservation is the State Historic Preservation Office.

Is metal detecting allowed in California State Parks? It depends on the park. Each unit posts its own order under 14 CCR § 4326. Many historic parks ban detectors, so check the specific park before going.

Can I metal detect in the California desert? Often yes, on BLM land, as long as you stay off archaeological sites, out of national parks and the Mojave National Preserve, and off active mining claims.

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.
