Morro Bay to Hatch: Epic Desert Road Trip Guide

This 600-mile route connects the foggy Pacific coast at Morro Castle to the red-rock heart of Utah, crossing the Mojave Desert via CA-58, I-15, and UT-20.

You'll drive through the Carrizo Plain, one of California's last remaining native grasslands, and skirt the edge of Death Valley National Park.
