Santa Cruz to Santa Rosa: Coastal to Wine Country Drive

The 108-mile journey from Santa Cruz to Santa Rosa via CA-17 and US-101 crosses the Santa Cruz Mountains, descends into the Silicon Valley sprawl, then meanders through the Sonoma wine country. This route, a blend of winding mountain passes and straight freeway, offers a microcosm of California's diverse landscapes.

CA-17 winds through the Santa Cruz Mountains, a remnant of the Franciscan Complex. This road, infamous for tight curves and fog, was once a stagecoach route. The highway crosses the San Andreas Fault near Los Gatos.
