King County (http://www.metrokc.gov/) is the largest county in Washington State by population, home to roughly 30% of the state's residents. It stretches from Puget Sound to the Cascade Range, encompassing the major cities of Seattle and Bellevue and their sprawling suburbs, as well as wide stretches of rural farmland and uninhabited mountain terrain.
