For Colorado, separate three questions: may you use a detector at this site, may you disturb the ground, and may you remove the object you locate? The state-park resource rule and archaeological ownership law do not answer every modern lost-property or local-park question. Start with the park or land manager before planning recovery.

The rules, land by land
State parks
Varies by siteColorado's state-park rules have no metal-detector provision, so detecting is set park by park through posted closures; ask the park, and do not remove protected objects (#100.C.2).
- no statewide detector rule in CPW Chapter P-1 (#100.C general rules or #100.D park-specific restrictions)
- parks may post areas against any entry or use (#100.C.1)
- removing objects of archaeological, geological, historical or natural value is prohibited (#100.C.2)
What the rule says
“To enter, use or occupy Parks and Outdoor Recreation Lands when same are posted against such entry, use or occupancy.”
Keeping finds
ProhibitedRemoving any object of archaeological, geological, historical or natural value from Colorado state park and outdoor recreation lands is prohibited.
- applies on all CPW parks and outdoor recreation lands
- exception: recreational gold mining in Arkansas Headwaters Recreation Area unless posted
What the rule says
“To remove, destroy, mutilate, modify or deface any structure, water control device, poster, notice, sign or marker, tree, shrub or other plant or vegetation, including dead timber and forest litter, or any object of archaeological, geological, historical, zoological or natural/environmental value or interest on Parks and Outdoor Recreation Lands.”
State & public land
No verdict yetNo cited source sets a detector rule for Colorado state land outside state parks; C.R.S. §24-80-401 et seq. governs ownership and excavation of archaeological resources (see the dig and keep rules), and CPW's wildlife-property rules (W-9) are silent on detectors.
Keeping finds
ProhibitedHistorical, prehistorical and archaeological resources on Colorado state land and waters belong to the state.
- includes rivers, lakes and reservoirs owned by the state
- resources include deposits, structures, objects, fossils and other remains (§24-80-401(1))
- on State Wildlife Areas, CPW Chapter W-9 #900.C.8 also bars removing any object of archaeological, geological or historical value or interest
What the rule says
“The state of Colorado reserves to itself title to all historical, prehistorical, and archaeological resources in all lands, rivers, lakes, reservoirs, and other areas owned by the state or any county, city and county, city, town, district, or other political subdivision of the state.”
Digging
Research permits onlyExcavating historical or archaeological resources on Colorado public land needs a state permit, issued only for museum, university or other scientific work.
- applies to historical, prehistorical and archaeological resources
- permit from the state historical society (§24-80-406(1))
- without a permit: class 2 misdemeanor, finds forfeited (§24-80-409(1))
What the rule says
“The investigations, excavations, gatherings, and removals shall be undertaken only for the benefit of reputable museums, universities, colleges, or other recognized scientific or educational institutions”
Lake shores
Varies by siteA shoreline inside a state park is still subject to park rules (no P-1 detector rule; posted closures apply). Shores run by cities, water districts or federal agencies were not read: identify the manager and check the search area and recovery conditions.
City / county parks
No verdict yetNo detecting rule was confirmed for city or county parks in Colorado; ask the park manager.
Keeping finds
ProhibitedHistorical, prehistorical and archaeological resources on county, city and town land in Colorado belong to the state.
- counties, cities, towns, districts and other political subdivisions
- excavating them without a permit is a class 2 misdemeanor (§24-80-409(1))
What the rule says
“The state of Colorado reserves to itself title to all historical, prehistorical, and archaeological resources in all lands, rivers, lakes, reservoirs, and other areas owned by the state or any county, city and county, city, town, district, or other political subdivision of the state.”
Federal land
No verdict yetA general federal-land detector rule was not confirmed in this review; ask the specific land manager.
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 Colorado state parks
The current CPW Chapter P-1, headed 09/02/2026, prohibits removal or damage to vegetation and objects of the protected kinds listed in #100.C.2. It also contains a limited recreational-gold-mining exception for Arkansas Headwaters Recreation Area, subject to posted restrictions. That exception should not be treated as detector access to every park or a right to remove historic objects.
Ask the specific park whether a detector is allowed, which areas and recovery tools are authorized, and how found property must be handled. The resource-protection clause is not a universal detector permit and should not be paraphrased as ownership of every object someone might lose. Do not disturb protected resources while investigating a signal.
Colorado’s antiquities law
In the 2026 Colorado Revised Statutes, Title 24, §24-80-401 reserves state ownership of historical, prehistorical and archaeological resources on state and local-government land, including the specified waters. Section 24-80-405 assigns the state archaeologist the role of issuing archaeological-study permits to qualified applicants. These provisions protect those resources; they do not justify treating all modern lost coins and jewelry as archaeological property. The land manager’s rules and found-property requirements still matter.
Public land, lakes & local rules
Identify who manages the reservoir shore, park or parcel. This review does not establish access for every Colorado municipality or federal unit. Obtain that manager’s current detecting and recovery rules rather than assuming federal land is uniformly more or less restrictive. Our land-manager guide explains the different agencies to check.

Frequently Asked Questions
- Is metal detecting legal in Colorado state parks?
- Check the individual park’s detecting and recovery policy. CPW Regulation #100.C.2 protects vegetation and specified resources; it is not a blanket authorization to detect or dig. Ask about the area, tools and treatment of finds before your visit.
- Can you keep what you find in a Colorado state park?
- Do not assume so. Protected resources are covered by CPW rules and archaeological ownership law. For modern lost property, ask the park about recovery and reporting requirements; a detector signal does not establish a right to keep an object.
- What about national forest or BLM land in Colorado?
- Federal land has separate agency and site rules. This state-law review does not establish access to a national forest or BLM parcel. Check with the responsible office for your intended search area, activity and recovery method.
