Start with the exact land manager, not just the state name. California state parks have resource-protection regulations and park-specific posted orders. City beaches, county parks and federal land need separate checks. The three gold-country park orders below show why a rule for one park cannot be treated as statewide permission. State-park rules prohibit disturbing earth or sand, so ordinary buried-target recovery is prohibited even where no detector-specific order was found.

The rules, land by land
State parks
ProhibitedRecovering a buried target is prohibited by the general ban on disturbing earth or sand in California state parks; separate park orders can also restrict carrying or using detectors.
- The detector verdict follows the ban on disturbing earth or sand for target recovery (14 CCR §4307), not a statewide ban on sweeping. The rockhounding exception is not established here as authorization for detector recovery.
- set unit by unit by District Superintendent posted orders (14 CCR §4326)
- Marshall Gold Discovery SHP, Folsom Lake SRA, Auburn SRA: possessing or using a detector prohibited
- exceptions there: transport in a vehicle on a public road; permit under 43 CFR 423.50; written exception from the Gold Fields District Superintendent
What the rule says
“No person shall destroy, disturb, mutilate, or remove earth, sand, gravel, oil, minerals, rocks, paleontological features, or features of caves except rockhounding may be permitted as defined and delineated in Sections 4610 through 4610.10.”
Digging
ProhibitedDisturbing or removing earth or sand in a California state park unit is prohibited, which rules out digging to recover a target (the only exception is rockhounding under 14 CCR §§4610-4610.10).
- statewide in State Park System units
- exception only for rockhounding under 14 CCR §§4610-4610.10
What the rule says
“No person shall destroy, disturb, mutilate, or remove earth, sand, gravel, oil, minerals, rocks, paleontological features, or features of caves except rockhounding may be permitted as defined and delineated in Sections 4610 through 4610.10.”
Keeping finds
ProhibitedRemoving any object of archaeological or historical interest or value from a California state park unit is prohibited.
- objects of archaeological or historical interest or value
What the rule says
“No person shall remove, injure, disfigure, deface, or destroy any object of archaeological, or historical interest or value.”
State & public land
No verdict yetNo cited source sets a detector rule for California state land outside the State Park System; PRC §5097.5 governs excavating and removing archaeological and historical features on public land (see the dig and keep rules).
Digging
Permit requiredExcavating an archaeological, paleontological or historical site on California public land, including city and county land, needs the express permission of the agency that manages it.
- covers historic or prehistoric ruins, burial grounds, archaeological or vertebrate paleontological sites, fossilized footprints, inscriptions, rock art and any other archaeological, paleontological or historical feature on public land
- allowed only 'with the express permission of the public agency having jurisdiction over the lands' (§5097.5(a))
- 'public lands' includes land owned by or under the jurisdiction of the state or any city, county, district, authority or public corporation (§5097.5(b))
- violation is a misdemeanor: fine up to $10,000, county jail up to one year, or both (§5097.5(c))
What the rule says
“A person shall not knowingly and willfully excavate upon, or remove, destroy, injure, or deface, any historic or prehistoric ruins, burial grounds, archaeological or vertebrate paleontological site”
Keeping finds
Permit requiredRemoving archaeological, paleontological or historical features from California public land needs the express permission of the agency that manages it.
- covers historic or prehistoric ruins, burial grounds, archaeological or vertebrate paleontological sites, fossilized footprints, inscriptions, rock art and any other archaeological, paleontological or historical feature on public land
- allowed only 'with the express permission of the public agency having jurisdiction over the lands' (§5097.5(a))

What the rule says
“A person shall not knowingly and willfully excavate upon, or remove, destroy, injure, or deface, any historic or prehistoric ruins, burial grounds, archaeological or vertebrate paleontological site”
Beaches
Varies by siteState-park beaches follow the same park rules and unit posted orders, with no blanket beach exemption. City and county beaches set their own rules, which were not read here. Confirm with the manager.
City / county parks
No verdict yetNot yet confirmed: no cited source sets a detecting rule for California city or county parks; check the specific parks department.
Even where detecting is allowed, archaeological and historic sites are protected, and you must fill every hole and follow posted rules. Always confirm the current rule with the land manager.
Metal detecting in California state parks
The State Parks regulation excerpts distinguish §4307 (geological features, including earth and sand), §4308 (archaeological and historical objects), and §4326 (compliance with posted orders). Resource protections constrain recovery even where an order does not mention detectors.
There are separate orders for Marshall Gold Discovery SHP (690-039-2023), Folsom Lake SRA (690-006-2025), and Auburn SRA (690-053-2026). Each restricts possessing and using detectors. Each lists transport without use in a vehicle on a public road and the specified federal permit provision as exceptions, and provides for a written exception from the Gold Fields District Superintendent. These provisions do not grant blanket permission for ordinary recreational hunting. State-park rules prohibit disturbing earth or sand, so ordinary buried-target recovery is prohibited even where no detector-specific order was found.
Check the park’s current orders and ask its office whether your planned activity and recovery method are authorized. Obtain any required written approval before the visit. The cited orders do not establish a universal written-permission requirement for every California state park.
California’s antiquities law (Public Resources Code §5097.5)
PRC §5097.5 protects specified historical, archaeological and paleontological features on public land. Knowingly and willfully disturbing them without the responsible public agency’s express permission is a misdemeanor, with a maximum $10,000 fine, up to one year in county jail, or both. The section defines public land broadly, including state and local-agency land. It is not a general license to collect other objects: access, park rules and other protections still need checking.
Beaches in California
Beaches managed by California State Parks fall under the same Title 14 rules and superintendent orders — there is no statewide ‘beaches are open’ exemption. Municipal and county beaches set their own rules, which we haven’t surveyed. The only reliable move is to confirm who manages the specific beach and what their policy is before you dig.
City and county parks
Local parks are governed by local ordinance, and we haven’t surveyed California’s cities and counties. Check the specific city or county parks department’s rules.
Don’t forget federal land
Federal land has separate managing agencies and rules. A state or local permission does not authorize activity there. Use our national guide to identify the relevant agency, then confirm the current site-specific restrictions with that agency.

Frequently Asked Questions
- Can you metal detect in California state parks?
- Check the specific park. Statewide resource protections and local posted orders apply. Separate orders at Marshall Gold Discovery, Folsom Lake and Auburn restrict detector possession and use, with limited exceptions. They do not establish one statewide detector-permit rule. State-park rules prohibit disturbing earth or sand, so ordinary buried-target recovery is prohibited even where no detector-specific order was found.
- Is it illegal to metal detect on public land in California?
- It is illegal to excavate, remove, or deface archaeological or historic features on any California public land without the managing agency’s permission — a misdemeanor under Public Resources Code §5097.5, punishable by a fine of up to $10,000, up to a year in county jail, or both. Always get the land manager’s OK first.
- Can you metal detect on California beaches?
- It depends who manages the beach. State-park beaches follow state-park rules, with no blanket exemption; city and county beaches set their own rules. Confirm with the specific manager before detecting.
