Arizona is a flat no in its state parks — the agency says so on its own FAQ — and a statewide antiquities law protects archaeological sites on state land. Detectorists still have options on the right federal or private ground, but the state-park and State Trust rules are stricter than many assume. Here’s the detail.
At a glance
| State parks | Restricted Arizona State Parks & Trails prohibits metal detecting throughout the entire state park system to protect park resources. |
|---|---|
| State & public land | Restricted Arizona Antiquities Act (A.R.S. §41-841 et seq.) bars excavating or collecting archaeological or vertebrate paleontological specimens on state land without a permit. |
| Public land & lakes | Depends Landlocked; lake/river shorelines follow the managing agency. The State Trust Land recreation permit does NOT authorize prospecting or treasure hunting. |
| Local & federal | Depends Gold prospecting mostly happens on federal BLM/Forest land; city/county park rules vary. |
*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 Arizona state parks
Arizona State Parks & Trails states in its official FAQ: “No. In order to conserve and protect the resources of the parks, we do not allow metal detecting.” Its Archaeological Site Etiquette page reinforces that detecting is not permitted in Arizona state parks and cannot be used to search for relics on public lands. There is no permit exception.
Arizona’s antiquities law
The Arizona Antiquities Act (A.R.S. §41-841 et seq.), administered by the Arizona State Museum, prohibits excavating or collecting archaeological or vertebrate paleontological specimens on state-owned or state-controlled land without a permit, and requires reporting discoveries. The law focuses on items at least 100 years old (arrowheads, coins, and bottles are specifically excluded from the “archaeological specimen” definition).
Public land, State Trust land & federal
Arizona is landlocked; lake and river shorelines follow whichever agency manages the land. On Arizona State Trust Land, the standard recreation permit does not authorize prospecting, treasure hunting, or rockhounding — those need a separate lease. Recreational gold prospecting mostly happens on federal BLM and National Forest land under federal rules; national parks and monuments prohibit detecting. See our national guide for the federal picture.
