Is Metal Detecting in Public Parks Legal in Maine After the 2026 Regulatory Updates?

No. Metal detecting in Maine’s public parks is prohibited unless explicitly permitted by local ordinances or the Maine Department of Agriculture, Conservation and Forestry’s Bureau of Parks and Lands. State law (38 M.R.S. § 447) vests park management authority in local governments, which may impose additional restrictions or outright bans. Violations may result in fines up to $500 under 12 M.R.S. § 1805-A.

  • State Park Restrictions: The Bureau of Parks and Lands (BPL) prohibits metal detecting in all state parks (e.g., Acadia, Baxter) without prior written authorization, citing preservation of archaeological resources under 17 M.R.S. § 285.
