Darrington is a town in Snohomish County, Washington, United States. The population was 1,347 at the 2010 census. The upper Stillaguamish valley where Darrington is located was once settled by the local Sauk-Suiattle Tribes in the drainage of the Sauk, Suiattle and Whitechuck rivers abundant in salmon and other fish. In 1870 a group of surveyors working for the Northern Pacific railroad came to the area to chart a pass over the Cascade Mountains to the Wenatchee Valley. Although a suitable route was found, the railroad chose a route further south. Gold was discovered at Monte Cristo in the summer of 1889 and prospectors began to flood into the Cascade Mountains. A road was punched in to Monte Cristo from Sauk City on the Skagit River. The location of where Darrington is now became a half-way point on the road, then a boomtown called "Starve Out".
