South of Aberdeen, the tour cuts through a forested area to the meandering shore lines of Willapa Bay, home of the Pacific Oyster industry, a region of quiet lagoons and great oyster flats, redolent at low tide with pungent marsh grass and drying seaweed. Entering a wooded section, the highway comes out upon a long stretch of ocean beach, where a side road leads through a scattering of gay seaside resorts, and graying hamlets, remnants of Washington’s earliest pioneering. Continuing southward, the tour emerges at the mouth of the broad Columbia, where a ferry connects with Astoria, Oregon.
