Can you go metal detecting on San Diego beaches?

3 min read Checked October 6, 2026

On City of San Diego beaches, generally yes: the city's beach rules don't ban detectors. State beaches set rules park by park, so call first, and Cabrillo National Monument bans even carrying one. Fill your holes.

The short version

  • Who owns the sand decides the rules: the City of San Diego, California State Parks or the federal government.
  • We found no metal-detector ban in the City of San Diego's park and beach regulations, so city beaches like Mission Beach, Pacific Beach and Ocean Beach are generally open to detecting.
  • State beaches (Torrey Pines, Silver Strand, Carlsbad, Cardiff) follow orders set by each park's superintendent; state rules ban disturbing sand, rocks or minerals without permission.
  • Federal rules ban possessing or using a metal detector in national park areas, which includes Cabrillo National Monument.
  • Filling your holes is etiquette, not a specific city law, but it's what keeps detecting tolerated.

San Diego's coastline is a patchwork of owners, and the patchwork matters more than the sand. Torrey Pines City Beach and Torrey Pines State Beach sit side by side under different agencies with different rules. Here's how to tell where a detector is welcome.

Who owns the beach, and what it means for detecting

California State ParksTorrey Pines State Beach, Silver Strand, Carlsbad, CardiffSet unit by unit by the superintendent; call the San Diego Coast District first

Other citiesCoronado, Oceanside, EncinitasNo published ban found; check with the city before you go

Why state beaches are different

California State Parks rules make it illegal to disturb or remove earth, sand, rocks or minerals in a park, and each park's superintendent can issue orders allowing or banning metal detectors. There's no single statewide answer, so the only reliable move is to ask the district before you dig.

  • Fill every hole. Open holes trip people and anger lifeguards.
  • Work the low tide. The wet sand near the waterline is where dropped rings and coins settle after a busy day.
  • Return what's identifiable. A ring with an engraving deserves a lost-and-found post or a call to lifeguards.
