Status: metal detecting is subject to state park restrictions on use, digging and keeping finds.
Colorado Parks and Wildlife regulation (2 CCR 405-1, Chapter P-1, Reg #100.b.2) does not prohibit metal detecting itself, but it is unlawful to remove, destroy or deface 'any object of archaeological, geological, historical, zoological or natural/environmental value' from park land - so you can swing a detector, but in practice you can't legally keep most coins, relics or artifacts you find. Individual park managers may impose additional site-specific restrictions (none of the 18 parks with special rules currently name metal detecting specifically), so it's wise to call ahead.

Check the specific property before detecting
A federal land overlay is a starting point, not permission. Check the managing office for the specific parcel, closures, detecting rules and restrictions on digging or removing objects. Never detect on archaeological sites or remove protected artifacts. ARPA protects archaeological resources over 100 years old on federal and Indian lands; other protections may apply to newer objects. National Park restrictions and state and local rules also apply. See our legal guidance.
Getting permission on private land
Use the county parcel office to identify the owner, ask before entering, and agree on where you may search and how finds will be handled. In the map, tap a location, check land information and save the spot. Use Asks to record permission requests and the letter tool to prepare an owner request. A saved spot or generated letter does not grant permission.
Using the map for research
- Open the state map and use Layers to show settlement records or beaches. Zoom in to explore individual markers.
- Compare historical maps with the current landscape. A GNIS historical designation does not establish that a location is abandoned or accessible.
- Check ownership and current rules before visiting. Named beaches are database records, not a verified list of public swimming or detecting areas.

No. Settlement and beach records are research leads, not public-access or detecting permission. Check the property manager, current restrictions and ownership before visiting. An empty federal-land result does not establish private ownership.
Colorado has 1,906 old and unincorporated settlement locations in federal records, including 105 marked historical in GNIS, plus 1 named public-record beaches. Old settlement sites, early schools and churches, old fairgrounds, and storm-scoured beaches are classic productive ground - with permission.
