America's Scenic Byways

Mountains to Sound Greenway - I-90

100 miles - 1.5 to 2 hours to drive the byway.

Drive east from Seattle on I-90 through pastoral valleys, lush forests and a dramatic mountain landscape. Visit historic towns and scenic spots for forest walks or challenging hikes. Cross the Cascades into a drier climate where coal mining built pioneer towns on the way to the Columbia River.
