About Sun

Valley

Sun Valley, located between Terra Linda and downtown San Rafael, is a residential and hillside San Rafael neighborhood with winding canyon roads and oak-studded open space. The neighborhood’s character concentrates around the Sun Valley School campus and the nearby bend of San Anselmo Avenue, where morning drop-offs and dog-walk loops set the daily rhythm. Mid-century ranch homes and tucked-away cottages follow the contours of the valley, with trailheads threading into the surrounding ridgelines. The Marinwood Community Center and Pool reads as a local gathering point for laps, classes, and weekend events. Marinwood Market anchors the practical errands, while China Camp State Park frames the outdoor backdrop with bayfront trails and history.
