California doesn’t give a simple yes-or-no on metal detecting. The rules come from a mix of statewide park regulations (California Code of Regulations, Title 14), park-by-park superintendent orders, and a strong statewide antiquities law — and several of the state’s most detector-tempting historic and gold-country parks ban detectors outright. Here’s what the law actually says, and how to stay on the right side of it.
At a glance
| State parks | Depends No blanket ‘yes.’ Governed by CCR Title 14 plus each park’s superintendent orders; several gold-country units ban detectors outright. Where allowed at all, you need written permission from the District Superintendent. |
|---|---|
| State & public land | Restricted Public Resources Code §5097.5 makes it a misdemeanor (up to $10,000 and/or a year in jail) to excavate, remove, or deface archaeological or historic features on any public land without the managing agency’s permission. |
| Beaches | Depends State-park beaches follow the same park rules — no blanket exemption. City and county beaches set their own rules and are sometimes more permissive. Confirm with the manager. |
| City / county parks | Depends Governed by local ordinance — check the specific parks department. |
*Even where detecting is allowed, archaeological/historic sites are protected and you must fill holes and follow posted rules. Always confirm the current rule with the specific land manager.
Metal detecting in California state parks
California State Parks doesn’t publish a single ‘metal detecting is allowed/banned’ rule. Instead, detecting is constrained by the resource-protection regulations in the California Code of Regulations, Title 14 — including §4307 (no disturbing geological features) and §4326 (no disturbing or removing archaeological or historic features) — layered with orders issued by each park’s district superintendent.
Some units ban detectors flat-out. Under a Gold Fields District superintendent order, Marshall Gold Discovery State Historic Park, Folsom Lake State Recreation Area, and Auburn State Recreation Area prohibit even possessing a metal detector within the park, let alone using one — exceptions only by written approval of the District Superintendent. Given how many detectorists are drawn to gold country, that’s an important one to know.
The safe way to read California: assume you need written permission from the park’s District Superintendent before detecting in any state park unit, and treat the historic gold-country parks as hard no’s.
California’s antiquities law (Public Resources Code §5097.5)
Beyond park rules, California Public Resources Code §5097.5 makes it a misdemeanor to knowingly excavate, remove, destroy, injure, or deface any archaeological or historic site or feature on public land without the express permission of the agency that has jurisdiction — punishable by a fine up to $10,000 and/or up to a year in county jail. ‘Public land’ here is broad: state, city, county, district, and other public-agency land. Additional protections for Native American cultural sites appear at §5097.9 and following.
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. Many municipal and county beaches set their own, sometimes more permissive, rules. 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, which varies from city to city. Some California municipalities allow detecting, some require a permit, and some prohibit it. Check the specific city or county parks department’s rules.
Don’t forget federal land
California has a lot of federal land, and it plays by federal rules. National parks, monuments, and seashores (Point Reyes, for example) prohibit metal detecting under 36 CFR 2.1. National forests and BLM land are more permissive but still protect archaeological sites — see our national guide to where you can metal detect.

Frequently Asked Questions
- Can you metal detect in California state parks?
- Generally not without written permission. California state parks are governed by CCR Title 14 resource rules and per-park superintendent orders, and several gold-country units — Marshall Gold Discovery State Historic Park, Folsom Lake State Recreation Area, and Auburn State Recreation Area — ban detectors outright. Where detecting is allowed at all, you need written permission from the park’s District Superintendent.
- 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 up to a $10,000 fine and/or a year in jail. 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 and are sometimes more permissive. Confirm with the specific manager before detecting.
