Santa Cruz to Yountville: Coastal to Wine Country Drive Guide

The 120-mile route from Santa Cruz to Yountville traces the historic El Camino Real, passing through the Santa Cruz Mountains and the fertile Santa Clara Valley before ascending into the Napa Valley. In 1769, Spanish explorer Gaspar de Portolà led the first European land expedition through this corridor, and today, Highway 17 and Interstate 880 carry travelers over the same terrain. The drive takes roughly 2.5 hours without traffic, but the journey warrants a full day to explore its diverse landscapes.

Leaving Santa Cruz, the redwood forests of Henry Cowell Redwoods State Park flank the highway. The 1906 earthquake shifted the San Andreas Fault through this area, creating the Ben Lomond Mountain ridge. As you descend into the Silicon Valley, orchards give way to tech campuses. The best stops Santa Cruz, CA to Yountville, CA include the Gilroy Garlic Fields—spring blooms of purple garlic flowers—and the rolling hills of Livermore Valley wine country.

In Yountville, the original Beringer Vineyards (founded 1876) offers cave tours. Downtown, the Napa Valley Wine Train departs from a restored 1915 depot. For a taste of local commerce, visit the Napa Farmers Market (Saturdays) or the Oxbow Public Market.

Electric vehicle charging stations are available at the Gilroy Premium Outlets and in downtown Napa.
