About Trinity County
Trinity County is a county located in the northwestern portion of the U.S. state of California. Trinity County is rugged, mountainous, heavily forested, and lies along the Trinity River (for which it is named) within the Salmon, Klamath Mountains, as well as a portion of the Scott, Trinity, and North Yolla Bolly Mountains. It is also one of three counties in California with no incorporated cities (the other two counties in California with that distinction are Alpine and Mariposa counties).
