The Mountains to Sound Greenway is home to a world-class regional trail system. A key Greenway goal is to fill in the few missing links between these major trails so that a hiker or biker may travel, safely off-road, from the shores of Puget Sound in Seattle, head east across the Cascade Mountains and all the way across Washington State.
