Chelsea by the Bay, located between Refugio Valley and San Pablo Bay, is a waterfront and residential Hercules neighborhood with bayfront trails and hillside views. Townhome-lined streets and newer single-family builds give it a clean, planned architectural feel. The neighborhood’s character concentrates around the Bayfront Boulevard and John Muir Parkway corridor, where landscaped medians, trailheads, and marina-bound traffic set a coastal, on-the-move rhythm. Nearby anchors such as the Hercules Bayfront (Refugio Landing), the Hercules Library, and the Hercules Swim Center function as local gathering points. Shoreline paths and pocket parks shape daily routines, while I-80 edges the inland side for regional connections.
