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

Yes, metal detecting in Puerto Rico’s public parks is generally prohibited under local environmental and cultural preservation laws, with rare exceptions for permitted archaeological activities. The Ley de Patrimonio Arqueológico de Puerto Rico (Law 111-2004) and Reglamento sobre Antigüedades y Tesoros (2023 amendments) strictly regulate artifact removal, classifying it as a misdemeanor punishable by fines up to $5,000 or imprisonment. The Departamento de Recursos Naturales y Ambientales (DRNA) enforces these rules, aligning with the 2026 Plan de Conservación de Sitios Históricos to protect pre-Columbian and colonial-era artifacts. Violations may also trigger federal scrutiny under the Archaeological Resources Protection Act (ARPA) if federal funds are involved.

Unauthorized removal of artifacts is classified as theft under Artículo 167 del Código Penal.
  • Environmental Impact Restrictions: The DRNA prohibits activities that disturb soil or vegetation in protected areas, including parks under the Sistema de Parques Nacionales or Bosques Estatales. Violators face administrative penalties under Reglamento 6766 (2022).
