Havillah is a small unincorporated agricultural community located in northeastern Okanogan County, eighteen miles south of the Canadian border. Havillah hasn’t changed much since the early settlers arrived. Go back in time and enjoy Havillah’s rich history and raw beauty. Not to be missed: the restored flour mill school house. Stop for birdwatching and wildlife viewing at Curlew Lake State Park & Driscoll Island Bird Sanctuary.
