The portion of this tour crossing the Cascade Mountains follows the Chinook Pass Scenic Byway. Dominated by majestic Mt. Rainier at every turn, this All-American Road traces the historic Naches Trail trading route between Enumclaw and Naches. At 5,430 feet, Chinook Pass marks a dramatic change in the landscape, separating the dense cedar and fir forests on the westside of the Cascade Mountains from the massive basalt cliffs of the Columbia Plateau on the eastside.
As both ends of the tour near their destinations, they pass through dense agricultural areas, river bottoms, and tribal lands. The portion running between Tacoma and Olympia for this tour follows Interstate 5 to provide the most expedient connection. Refer to the Seattle to Olympia leg of the Canadian Border to Vancouver tour for an alternate connection between Tacoma and Olympia.
