Tice Valley, located between Rossmoor and Walnut Creek, is a semi-rural and residential Castle Hill neighborhood with rolling hills and equestrian pockets. The neighborhood’s character concentrates along Tice Valley Boulevard near the I-680 overpass, where trailheads, ranch-style driveways, and a low-key roadside rhythm set the tone. Ranch homes and mid-century properties sit behind oaks, with open-space views shaping daily routines. The Iron Horse Regional Trail and nearby Las Trampas ridgelines frame a walk-and-ride lifestyle. Community touchstones include Heather Farm Park, the Lesher Center for the Arts, and the Ruth Bancroft Garden & Nursery. Shopping and dining cluster in Walnut Creek’s downtown grid, while the valley itself stays quiet and green.
