Walla Walla to Tillamook: Wine Country to Coast Road Trip Guide

The route from Walla Walla, WA to Tillamook, OR covers roughly 350 miles, crossing the Columbia River, the Cascade Range, and the Coast Range. The drive is a study in contrasts: you begin in the wheatfields and vineyards of the Palouse and end in the misty rainforests of the Oregon Coast. Historically, this path follows the Oregon Trail corridor, though modern highways have shifted east and west.

One defining fact: the descent from the Cascade summit at Santiam Pass (elevation 4,817 feet) drops over 4,000 feet in 60 miles as you approach the coast. This dramatic elevation change influences everything from fuel economy to weather.
