Bristol: Jasper Rockhounding in Bristol County, Rhode Island

Updated July 2026

The Bristol shoreline, including the public waterfront at Colt State Park and the town beaches, yields red and brown jasper pebbles along with occasional agate and quartz from the Narragansett Basin conglomerates. Bristol sits on the western arm of Mt. Hope Bay, so the same chalcedony-bearing gravels wrap the whole peninsula. It is an easy, family-friendly stretch of public bay shore for pebble picking. Reported finds include jasper. Below: coordinates, access notes, nearby spots, and trip-planning links.
