Warwick's Narragansett Bay beaches, including the public shore around Conimicut Point and City Park, are a long-known source of water-worn carnelian and agate pebbles. The many miles of low-energy cobble beach along Warwick's indented coastline give collectors more shoreline to work than almost anywhere else in Kent County. Surface picking through the pebble lines is the standard method. Reported finds include carnelian. Below: coordinates, access notes, nearby spots, and trip-planning links.

Land & collecting status

Generally open to casual rockhounding

Most public-tagged spots sit on BLM, U.S. Forest Service, or other federal land where reasonable hand collecting of common rocks and minerals is allowed. Confirm posted rules and active mining claims before you dig.

Access note: Public town beaches and shoreline. Conimicut Point Park and Warwick City Park offer parking and walk-in shore access. Collect loose surface pebbles only under Rhode Island shoreline access law, and avoid private beach associations and posted waterfront.

Public-land rules vary by agency, season, and field office. The RockHoundR app pulls live BLM, USFS, NPS, and tribal overlays so you can see exactly which agency manages the ground at this spot.
