California State Route 35 (Skyline Boulevard) is a north–south highway that follows the ridge of the Santa Cruz Mountains on the San Francisco Peninsula. The route links U.S. Route 101 near Los Gatos with State Route 92 near Half Moon Bay, traversing ridgelines, watersheds, and parklands. Renowned for scenic vistas, the road connects to regional parks, state parks, and preserves serving commuters, recreational users, and tourism related to the San Francisco Bay Area.
Route description
Skyline Boulevard begins at an interchange with U.S. Route 101 just south of Los Gatos and trends northwest along the crest of the Santa Cruz Mountains. Southbound, the highway overlooks Santa Clara Valley and provides access to Castle Rock State Park, Big Basin Redwoods State Park, and trailheads that lead to connections with Pacific Coast Trail alignments and the Bay Area Ridge Trail. As the route proceeds north, it intersects with county roads that lead to Saratoga, Monte Sereno, Boulder Creek, and Ben Lomond.
Further north, Skyline Boulevard passes near Sierra Azul Open Space Preserve and provides overlooks toward Mount Umunhum, Loma Prieta, and Monterey Bay. The road crosses multiple creeks in the Pescadero Creek watershed and intersects with State Route 84 at the La Honda area, offering routes toward Menlo Park and Palo Alto. Continuing into San Mateo County, the highway skirts Windy Hill Open Space Preserve and Purisima Creek Redwoods Open Space Preserve before terminating at State Route 92 near Half Moon Bay and Pillar Point Harbor.
The corridor is maintained by Caltrans and is part of regional scenic byway networks used by local media, regional planners such as the Association of Bay Area Governments and transportation agencies including the Metropolitan Transportation Commission.
History
The ridgetop corridor predates the numbered highway system, with early use by Ohlone people and later by Spanish colonial trails linked to Mission Santa Clara de Asís and Rancho San Antonio (Mesa del Corte Madera del Presidio). In the 19th century, logging and ranching by settlers from Yerba Buena and San Jose opened proto-roads across the crest to access redwood groves exploited by companies like L. T. and Company and later operations associated with the California Gold Rush logistics.
The modern designation as State Route 35 was assigned during mid-20th century state highway renumbering overseen by the California State Legislature and implemented by CSAA era maps and Caltrans planning. Road improvements reflected postwar automobile growth, with projects funded through state bond measures and federal programs such as those administered by the Federal Highway Administration. Periodic closures and realignments followed seismic events like the 1989 Loma Prieta earthquake and storm-related washouts, prompting emergency responses coordinated by California Governor offices and county public works departments.
Conservation advocacy by organizations including Save the Redwoods League, The Nature Conservancy, Sierra Club, and local groups influenced land-use decisions that preserved corridor segments as parkland and limited large-scale development in adjacent watersheds. Recent upgrades have emphasized safety, erosion control, and habitat connectivity in cooperation with agencies such as the California Coastal Conservancy and U.S. Fish and Wildlife Service.
