Metal Detecting in State Parks: Rules by State
There's no national rule for state parks. Each state sets its own, from designated beach areas to permits to outright bans, and state antiquities laws protect historic finds either way.
11 places in 6 states: 7 allowed, 3 permit required, 1 prohibited. Rules checked between and .
Every state writes its own park rules, so the same detector is welcome in one state's parks and banned in the next. In the parks we've checked:
- Florida state parks allow recreational detecting only on beach areas the park manager designates, between the toe of the dune and the high-water line. Florida Statutes Chapter 267 gives the state title to historic artifacts on state land.
- Michigan: at Warren Dunes only the unvegetated Lake Michigan shoreline is open; DNR Land Use Order 5.26 closes the rest of the park unless the manager authorizes it in writing. The DNR lists which parks are open and which have designated areas.
- New Jersey requires a written permit from the park superintendent (N.J.A.C. 7:2-2.16).
- New York's Long Island parks require a paid annual permit (9 NYCRR 372.7).
- Pennsylvania requires checking in with the park manager and getting approval before you start.
- Texas prohibits it at TPWD state parks without written authorization (31 TAC 59.134).
A detecting permit or open beach doesn't cover keeping historic or archaeological finds: state antiquities laws apply separately. See Florida's Chapter 267 and the Texas Antiquities Code.

The laws behind these verdicts
- Florida's Antiquities Law (Chapter 267) Explained for Metal DetectoristsFlorida Statutes Chapter 267 gives the state title to historic artifacts abandoned on state-owned land and sovereignty submerged land, and makes removing them without a permit a crime. Here's where that line falls on a beach, where the "50-year rule" actually comes from, and what to do if you find something old.
- The Texas Antiquities Code: What Metal Detectorists and Fossil Hunters Need to KnowTexas Natural Resources Code ch. 191 makes pre-1900 shipwrecks, "treasure imbedded in the earth" and archeological sites on state, county and city land the property of the State of Texas. Here is what it covers, what it doesn't (modern losses, fossils, private land), and what to do if you dig something old.
