Westside, located between Interstate 680 and the Las Trampas Regional Wilderness, is a residential and hillside San Ramon neighborhood with curving cul-de-sacs and trail-lined open space. The neighborhood’s character concentrates around the Bollinger Canyon Rd and San Ramon Valley Blvd corridor, where coffee counters, local eateries, and everyday errands cluster in a steady daytime hum. Architectural lines lean toward late-20th-century California ranch and two-story tract homes, often set against oak-dotted slopes. Weekends tend to orbit around nearby trailheads and the greenbelt feel of the valley floor. Community pillars include the Forest Home Farms Historic Park, the San Ramon Valley Historical Society, and the San Ramon Valley Community Center.
