Mesquite to Yountville: Ultimate Road Trip Guide via I-15 & CA-99

Driving from Mesquite, NV to Yountville, CA covers 650 miles of striking desert, mountain passes, and Central Valley farmland. The route follows I-15 south to the Cajon Pass, then cuts across on CA-58 and CA-99 before reaching the Napa Valley.
