Mtns to Sound Greenway

It's a route that may have travelers starting with a cup of coffee in the shadow of the Space Needle and ending in the spray of a 27-story waterfall. The Mountains to Sound Greenway combines the best of city life with remarkably accessible marvels of nature.

Stretching along Interstate-90 from Seattle and the Puget Sound to the high desert of central Washington is one of the most spectacular journeys in the Pacific Northwest. The Greenway is one of 3 nationally designated scenic byways in Washington, and is the only interstate highway in the country to have designation as a National Scenic Byway.
