Granite Falls is a city in Snohomish County, Washington, United States. The population was 3,364 at the 2010 census.
Before the arrival of European settlers, the area that is now Granite Falls was used by Natives to portage their canoes between fishing grounds.
The first permanent European settler was Joseph Sous Enas, who staked a homestead claim on land south of the present city. It then became a railroad station on the route between Monte Cristo (now a ghost town) and Everett. The city was officially incorporated on December 21, 1903.In the 21st Century, Granite Falls is focused on attracting more visitors to the stupendous beauty and recreational opportunities along the Mt. Loop Highway. Expanded housing development has brought an increased population of families who commute to Everett, Seattle, and the Eastside to work.
