Central San Bernardino Valley

The urban core of San Bernardino County, centered on the city of San Bernardino -- the county seat and a historic railroad hub undergoing revitalization. Fontana, one of the IE's largest cities, anchors the western edge with its industrial-residential mix along I-10. Rialto, Colton, and Grand Terrace fill the valley floor, while Highland stretches toward the San Bernardino Mountains. The Arrow commuter rail line (opened 2022) connects downtown San Bernardino to Redlands, and Metrolink provides service to LA. This region offers some of the most affordable housing in the metro with direct freeway access.
