Warwick: Carnelian Rockhounding in Kent County, Rhode Island

Updated July 2026

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.
