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.

Captain William Clark Park
On March 31, 1806, after learning from the native tribes that food was scarce to the east, Lewis & Clark ordered the Corps of Discovery to remain at “Provision Camp,” a location known today as Cottonwood Beach in Washougal, Washington.
The Corps stayed at Provision Camp for six days, the longest period of time the expedition spent at any location in Clark County. After procuring enough dried meat to last the trip through the Columbia River Gorge, the Corps set off once again, canoeing up the Columbia River towards Nez Perce territory on Sunday, April 6.
Presently, the Captain William Clark Park is a day-use-only park comprised of 93 acres of forested land located along the river. It’s open from 7am to dusk daily, and features fishing, accessible multiuse trails, historic interpretive exhibits, and restrooms.
