Byway Overview

Lewis and Clark's epic 572-mile adventure through Washington and along the Columbia River was among the most vivid and compelling episodes of
their journey. In 1805, the Corps of Discovery entered present-day Washington State near Clarkston in the Hells Canyon region where the Snake, Salmon and Clearwater rivers converge. Beacon Rock is noted as the first place they detected tidal influences and realized they were nearing the Pacific.
