Sisters is a city in Deschutes County, Oregon, United States. It is part of the Bend, Oregon Metropolitan Statistical Area. The population was 959 at the 2000 census, but more than doubled to 2,038 as of the 2010 census. Fun stays here year-round, with camping and fishing nearby at Suttle Lake and 800 acres of family-friendly ski terrain at Hoodoo Ski Area. In the summer, it’s all about the annual Sisters Rodeo. But you don’t need a season to taste all of the restaurants’ savory flavors — or soak in America’s first beer spa here.
