Central, located between Lake Chabot Regional Park and the Castro Valley BART station, is a residential and commercial Castro Valley neighborhood with a walkable downtown strip and hillside views. The neighborhood’s energy concentrates around Castro Valley Boulevard at Redwood Road, where sidewalk cafes, independent eateries, and small storefronts set a steady, day-to-night rhythm. Community pillars include the Castro Valley Marketplace food hall, the Chabot Cinema, and the Castro Valley Arts Foundation gallery and studios. Mid-century ranch homes and compact apartment buildings mix with newer infill near the boulevard. Green space and trailheads shape daily routines, with Lake Chabot’s shoreline paths close by. Transit and I-580 frame commutes while keeping the street life focused on the boulevard.
