The Stones, located between Refugio Valley Road and San Pablo Avenue, is a residential and hillside Hercules neighborhood with curving cul-de-sacs and bay-facing greenbelts. The neighborhood’s character concentrates around the Refugio Valley Road corridor by the Hercules Transit Center, where commuter buses, small service storefronts, and steady weekday motion set the tempo. Housing reads as late-20th-century California suburbia—stucco facades, attached garages, and tidy setbacks stepping up the slopes. Trails and pocket parks stitch the blocks to Refugio Valley Park’s open lawns and play areas. Waterfront air and wide skies filter in from the nearby shoreline. For a local night out, the community’s familiar pillars include The Powder Keg Pub, The Playhouse in Pinole, and the Contra Costa College Art Gallery.
