Idaho lets you detect in a state park only if the manager authorizes it in advance — and even then, you can’t remove anything historic, cultural, or natural. With so much federal land, checking ownership first is essential. Here’s the detail.
At a glance
| State parks | Depends Metal detecting is a “non-traditional recreational activity” that may be authorized in advance by the park or program manager; digging up or removing historical, cultural, or natural resources is prohibited. |
|---|---|
| State & public land | Restricted Idaho Code Title 67, Ch. 41 requires a State Historical Society permit to excavate a prehistoric site and bars removing relics/artifacts from public land without the board’s consent (misdemeanor + forfeiture). |
| Public land & lakes | Depends Landlocked; lake, reservoir, and river shores within parks fall under the same park rules; federal reservoir/river land under ARPA. |
| Local & federal | Depends Cities vary (Boise requires a paid permit); much of Idaho is federal BLM/USFS/USBR under ARPA. |
*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 Idaho state parks
Idaho state parks are governed by IDAPA 26.01.20 (Department of Parks and Recreation), Section 175 (“Public Behavior”). Subsection 11 lists metal detecting among “non-traditional recreational activities” that “may be authorized by the park or program manager if such activities do not interfere with traditional uses of the park and are consistent with preservation of park resources.” Subsection 09 separately prohibits “the digging, destruction or removal of historical, cultural or natural resources.” So you need the manager’s OK to detect at all, and you may not remove historic or cultural finds.
Idaho’s antiquities law
Idaho Code Title 67, Chapter 41 protects antiquities: §67-4120 requires a permit from the State Historical Society board before excavating a prehistoric site, §67-4121 bars removing relics, artifacts, petroglyphs, or specimens from any public land without the board’s consent, and §67-4122 makes a violation a misdemeanor plus forfeiture of all items acquired.
Public land, lakes & federal
Idaho is landlocked; lake, reservoir, and river shorelines within state parks fall under the same IDAPA park rules, and federal reservoir and river land (BLM, USBR, USFS, Corps) is separately governed by ARPA. Cities vary — Boise, for example, requires a paid Parks & Recreation metal-detecting permit and bars cemeteries and golf courses. Much of Idaho is federal land where ARPA prohibits disturbing artifacts over 100 years old, so check ownership before detecting. See our national guide.

Frequently Asked Questions
- Can you metal detect in an Idaho state park?
- Only if the individual park or program manager authorizes it in advance — metal detecting is treated as a “non-traditional recreational activity” under IDAPA 26.01.20.175(11), permitted only when it doesn’t interfere with traditional park uses or harm park resources. There is no blanket statewide right.
- Can you keep what you find in an Idaho state park?
- Generally no for anything of historical, cultural, or natural value — IDAPA 26.01.20.175(09) prohibits digging up or removing those resources, and Idaho Code §67-4121 requires the State Historical Society board’s consent to remove relics or artifacts from public land.
- What happens if you dig up an artifact without a permit in Idaho?
- Under Idaho Code §67-4122 it is a misdemeanor, and you forfeit to the state all items you acquired from the archaeological site. Section 67-4120 requires an excavation permit from the Idaho State Historical Society board first.
