Is Metal Detecting Legal in Arizona?

Metal detecting is legal on much of Arizona's federal land, but not in Arizona State Parks and not on Arizona State Trust land, even if you hold a State Land recreational permit. Most legal detecting in Arizona happens on Bureau of Land Management and national forest land, away from archaeological sites and active mining claims.

Arizona state parks: Arizona State Parks & Trails does not allow metal detecting. Its current visitor FAQ says detecting is not permitted in order to protect park resources, and there is no permit route for hobby use. An older rule that allowed shallow detecting on some beach areas has been replaced.

Other state land in Arizona: State Trust land is not public land. It covers about 9.2 million acres and requires a permit from the Arizona State Land Department for almost any use. The recreational permit ($15 individual, $20 family, per year) covers camping, hiking, and similar activities, but the permit terms specifically exclude metal detecting and removing rocks or other natural materials. Prospecting on Trust land requires a separate mineral exploration permit, not the recreational one.

Arizona's artifact law: The Arizona Antiquities Act (A.R.S. § 41-841 and following) protects archaeological and paleontological sites on state and other public land. Excavating or collecting from those sites without a permit issued through the Arizona State Museum is illegal.

Where you can legally metal detect in Arizona: BLM land, which covers about 12 million acres of Arizona, is the most common place for legal recreational detecting and gold prospecting. Coconino, Kaibab, Prescott, Tonto, and other national forests generally allow casual recreational detecting outside archaeological and historic sites. Private land works with the owner's written permission. City and county parks each set their own rules, so check with the parks department first.

Arizona-specific traps to avoid: Arizona's gold country (Wickenburg, Quartzsite, the Bradshaw Mountains) is heavily covered by active mining claims. Detecting for gold on someone else's claim is taking their minerals, even on BLM land, so check claim status first in the BLM's MLRS database. Grand Canyon, Petrified Forest, Saguaro, and every other National Park Service unit ban detectors outright. Tribal land covers more than a quarter of the state and requires permission from that nation.

For archaeologists and researchers in Arizona: Archaeological work on Arizona state land, including State Trust land, requires an Arizona Antiquities Act permit issued by the Arizona State Museum, which sets qualification standards for principal investigators. Work on BLM or national forest land requires a federal ARPA permit from that agency. Recorded site information is held by AZSITE, Arizona's cultural resource database, with access limited to qualified users. Consultation and compliance questions go to the State Historic Preservation Office, which is part of Arizona State Parks & Trails.

Can I metal detect on Arizona State Trust land with a recreation permit? No. The State Land Department recreational permit covers activities like camping and hiking, and its terms exclude metal detecting. Detecting on Trust land without separate authorization is a violation of the permit.

Is metal detecting allowed in Arizona State Parks? No. Arizona State Parks & Trails does not allow metal detecting in its parks.

Where can I legally metal detect for gold in Arizona? Mostly on BLM land and national forest land that is not under an active mining claim and is not an archaeological site. Check claim status in the BLM MLRS database before you go.

Federal land in every state: National Park Service units ban metal detectors (36 C.F.R. § 2.1), and the Archaeological Resources Protection Act protects archaeological resources 100 years or older on federal and tribal land. Professional excavation or removal on federal land requires an ARPA permit from the managing agency (43 C.F.R. Part 7). See our national overview for details.
