Cannon Beach, OR to St. Helena, CA: Ultimate Road Trip Guide

Stretching 650 miles along the Pacific Coast, the drive from Cannon Beach, Oregon to St. Helena, California follows a route that has been traversed for millennia.

This route also passes through the historic town of Leggett, home to the Chandelier Drive-Thru Tree, a giant redwood with a tunnel carved through its base in the 1930s.
