Port Townsend to Walla Walla: Epic WA Road Trip Guide

This 330-mile journey from Port Townsend to Walla Walla crosses Washington State from the Olympic Peninsula ferry town to the sunny wine country of the Palouse. The route primarily follows US-101 south, then I-5 east to I-90, and finally US-12 and US-395 southeast. A lesser-known fact: the stretch near Vantage crosses the Columbia River just downriver from the Wanapum Dam, where basalt cliffs reveal volcanic flows from 15 million years ago. The drive takes approximately 5.5 hours without stops, but plan for 7–8 hours to savor the diversity.
