In Texas the headline rule is simple: you can’t use a metal detector in a state park without a permit. Off the state-park system, cities set their own rules, and the Antiquities Code makes archeological sites on public land, and treasure buried in state land and tidelands, state property. Here’s the detail, with sources.

The rules, land by land
State parks
Permit requiredUsing a metal detector in a Texas state park is an offense unless a permit authorizes it, so ask the park before you bring one.
- only as authorized by permit
- disturbing rock, earth or soil also needs a permit from the director
- prehistoric or historic resources, including artifacts, may not be taken or disturbed without the director's written order
What the rule says
“It is an offense for any person to operate or use a metal detector, except as authorized by permit.”
Digging
Permit requiredDigging or otherwise disturbing rock, earth or soil in a Texas state park needs a permit from the director, and historic or prehistoric artifacts need the director's written order.
- permit issued by the director for any disturbance of rock, earth, soil, minerals or fossils
- artifacts and other prehistoric or historic resources: written order of the director only
What the rule says
“It is an offense for any person to take, remove, destroy, deface, tamper with, or disturb any rock, earth, soil, gem, mineral, fossil, or other geological deposit except by permit issued by the director.”
State & public land
No verdict yetThe Antiquities Code of Texas (Natural Resources Code ch. 191), administered by the Texas Historical Commission, protects archaeological and historic resources on non-federal public land.
Digging
Research permits onlyDigging into or recovering from an archeological site, or treasure imbedded in state land, tidelands or submerged land, needs a Texas Historical Commission permit or contract, and archeology permits go only to professional archeologists.
- landmarks include every archeological site on land of the state or a county, city or other political subdivision (§191.092)
- and all treasure imbedded in the earth on state land, tidelands, submerged land and river beds (§191.091)
- salvage or recovery operations need a contract (§191.131(a))
- THC archeology permits go only to professional archeologists who qualify as principal investigators
- misdemeanor: $50 to $1,000 fine, up to 30 days in jail, or both; each day a separate offense (§191.171)
What the rule says
“No person, firm, or corporation may conduct an operation on any landmark without first obtaining a permit and having the permit in his or its possession at the site of the operation, or conduct the operation in violation of the provisions of the permit.”
Keeping finds
ProhibitedArtifacts and archeological sites on land owned by Texas or a county, city or other political subdivision, and treasure imbedded in state land, tidelands or submerged land, are state property and may not be removed without a Texas Historical Commission permit.
- items of historical, archeological, scientific or educational interest on state or local public land (§191.092)
- pre-twentieth-century wrecks and all treasure imbedded in the earth on state land, tidelands, submerged land and river beds (§191.091)
- THC archeology permits go only to professional archeologists
- misdemeanor: $50 to $1,000 fine, up to 30 days in jail, or both; each day a separate offense (§191.171)
What the rule says
“Landmarks under Section 191.091 or 191.092 of this code are the sole property of the State of Texas and may not be removed, altered, damaged, destroyed, salvaged, or excavated without a contract with or permit from the committee.”
Beaches
Varies by siteTexas beaches have different managers. Beaches inside a state park need the park permit; no source here covers open Gulf beaches or city beaches, and the Antiquities Code makes treasure imbedded in state tidelands and submerged land a state archeological landmark.
- state-park beaches: permit under 31 TAC §59.134(i)
- open Gulf beaches and city beaches: no rule read; ask the beach manager
- treasure imbedded in the earth on state land, tidelands and submerged land is a state archeological landmark (Nat. Res. Code §191.091)
City / county parks
Varies by siteEach Texas city sets its own park rules: Austin permits detecting only to search for a specific lost item, while San Antonio issues six-month permits for developed parks.
- check the city or county parks department before you go
- Austin: permit only to search for a specific item lost during a park visit or event; general or hobby searches are refused; finds go to the city within 2 days
- San Antonio: permit from the Parks and Recreation Director's Office, up to 6 months and 20 listed parks, developed parks only, no digging tools
What the rule says
“Metal detecting permits are only approved for searches for specific items lost during a park visit or event, where reasonable searches have exhausted all other reasonable means of locating the lost item.”
Private land
Digging
Permit requiredOn someone else's enclosed land, digging into or removing any historic artifact, burial or archeological site without the owner's consent is a misdemeanor under the Antiquities Code.
- consent of the owner, proprietor, lessee or person in charge
- covers historical structures, monuments, markers, artifacts, burials and archeological sites on enclosed private land
- misdemeanor: $50 to $1,000 fine, up to 30 days in jail, or both (§191.171)
What the rule says
“No person who is not the owner, and does not have the consent of the owner, proprietor, lessee, or person in charge, may enter or attempt to enter on the enclosed land of another and intentionally ... dig into, or destroy any historical structure, monument, marker, medallion, or artifact, or any prehistoric or historic archeological site”
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 Texas state parks
The governing rule is 31 Texas Administrative Code §59.134 (‘Rules of Conduct in Parks’). Subsection (i) is explicit: ‘It is an offense for any person to operate or use a metal detector, except as authorized by permit.’ A related subsection protects park resources — you can’t take or deface rock, soil, minerals, fossils, or any prehistoric or historic resource without a permit or the director’s written order.
The rule names no issuing office, so ask the park itself about a permit. Either way, the rule is clear: no permit, no detecting in a Texas state park.
The Antiquities Code of Texas
Texas protects cultural resources on non-federal public land through the Antiquities Code of Texas (Natural Resources Code, Title 9, Chapter 191), administered by the Texas Historical Commission (THC). Every archeological site on land of the state or a county, city or other political subdivision is a State Archeological Landmark, and so is treasure imbedded in the earth on state land, tidelands and submerged land (§§191.091–.092). Landmarks are state property and may not be removed or excavated without a THC permit or contract (§191.093), and archeology permits go only to professional archeologists who qualify as principal investigators.
Beaches in Texas
Texas beaches are a mixed picture. Inside a state park, the §59.134 permit rule applies to the beach too. We haven’t found a source on detecting open Gulf beaches or city beaches outside parks, and the Antiquities Code makes treasure imbedded in state tidelands and submerged land a state landmark. Confirm the specific beach’s manager and rules before you go.
City and county parks
Texas cities set their own park rules. Austin’s permit form approves metal detecting only to search for a specific item lost during a park visit or event, so hobby hunting is refused; San Antonio issues permits for listed developed parks. Check the parks department for the city or county you plan to hunt.
Don’t forget federal land
Federally managed land has its own agency rules; do not transfer a state or local permission across its boundary. National Park Service land prohibits recreational metal detecting under 36 CFR 2.1(a)(7), subject to its possession and authorized-use exceptions. See our national guide for national forests and BLM land.

Frequently Asked Questions
- Can you metal detect in Texas state parks?
- Not without a permit. Under 31 TAC §59.134(i) it is an offense to use a metal detector in a Texas state park except as authorized by permit. The rule doesn’t say who issues permits, so ask the park.
- Do you need a permit to metal detect in Texas?
- In Texas state parks, yes. Outside the state-park system the state-park rule doesn’t automatically apply, but cities set their own rules (Austin, for example, approves only lost-item searches), and the Antiquities Code of Texas protects archaeological sites on public land statewide. Always check the specific land manager.
- Can you metal detect on Texas beaches?
- Inside a state park you need the park permit. We haven’t found a source on open Gulf beaches or city beaches, so ask the beach manager.
