Napa to Prescott: Epic Road Trip Through California and Arizona

This 12-hour drive along I-5, CA-58, I-15, and AZ-89 crosses three distinct ecoregions: the foggy wine valleys of Napa, the arid Mojave Desert, and the high pine forests of central Arizona. A little-known fact: the route passes within 10 miles of the historical site of the 1871 Camp Grant Massacre, a pivotal event in Apache-American relations.

With careful planning, you can experience everything from the world-class culinary scene of Napa Valley to the red-rock canyons of Sedona. The drive covers approximately 750 miles, best done over 3 days, but many stretch it to 5 to savor the stops.
