Morro Bay to Dunsmuir: Ultimate Road Trip Guide

The drive from Morro Bay to Dunsmuir covers roughly 380 miles along a route that transitions from the rugged Pacific coast to the volcanic terrains of the Cascade Range. This journey takes you through the heart of California's breadbasket and into the forests of the far north.

A notable quirk: just north of Redding, you'll cross the Pit River Bridge, one of the highest double-deck bridges in the United States, soaring 500 feet above the Pit River arm of Shasta Lake. This fact sets the stage for a trip filled with dramatic elevation changes and scenic viewpoints.
